65be80c3ed build: Rework path construction to reliably add prefix
There were a couple of custom paths which could end up being relative,
rather than absolute, due to not properly prefixing them with
`get_option('prefix')`.

The use of `join_paths()` here correctly drops all path components
before the final absolute path in the list of arguments. So if someone
configures GLib with an absolute path for `gio_module_dir`, that will be
used unprefixed; but if someone configures with a relative path, it will
be prefixed by `get_option('prefix)`.

8aeca4fa64 GThreadPool - Don't inherit thread priorities when creating new threads
By default (on POSIX) we would be inheriting thread priorities from the
thread that pushed a new task on non-exclusive thread pools and causes a
new thread to be created. This can cause any non-exclusive thread pool
to accidentally contain threads of different priorities, or e.g. threads
with real-time priority.

To prevent this, custom handling for setting the scheduler settings for
Linux and Windows is added and as a fallback for other platforms a new
thread is added that is responsible for spawning threads for
non-exclusive thread pools.

505c954424 build: Check size_t compatibility with various other types
When choosing the type to base `size_t` on, check the compatibility of
passing pointers, as well as the width of the type, to avoid compiler
warnings in future.

For now, the code to do the checks is fairly ugly due to limitations in
Meson. In particular, the new checks are limited to gcc and clang (other
compilers will behave as before), and they are all duplicated. See the
comments in the code for links to Meson improvement requests.

While I'm changing the build-tests condition anyway, deduplicate it.

00d7568e4f build: Remove unsupported install directives
We're using the `install` argument for configure_file() all over the
place.

The support for an `install` argument for configure_file() was added in
Meson 0.50, but we haven't bumped the minimum version of Meson we
require, yet; which means we're getting compatibility warnings when
using recent versions of Meson, and undefined behaviour when using older
versions.

The configure_file() object defaults to `install: false`, unless an
install directory is used. This means that all instances of an `install`
argument with an explicit `true` or `false` value can be removed,
whereas all instances of `install` with a value determined from a
configuration option must be turned into an explicit conditional.

e8d471f3e1 meson: Mostly assume clang-cl is MSVC
We need to enable building the dirent and gnulib sources for clang-cl,
as we are still using the Microsoft-style headers and lib's and CRT.
We need to also do this for the following, for similar reasoning:

-Symbol export (via __declspec(dllexport))
-Dependency discovery without pkg-config files
-long long and ssize_t detection

We do, however, enable the autoptr tests for clang-cl builds.  Note that
at this point real MSVC builds are still better supported than clang-cl
builds, and it will likely remain so for at least the near future,
alhtough real MSVC builds of the GTK stack are consumable and are usable
by clang-cl.

0030408299 gunicollate/cygwin: Don't use __STDC_ISO_10646__ for wchar_t related checks
The code in gunicollate uses __STDC_ISO_10646__ to check that wchar.h is avilable,
that it includes the wide character related functions and that sizeof(wchar_t) == 4.

cygwin defines __STDC_ISO_10646__ and has sizeof(wchar_t) == 2 and the C standard text isn't
that clear on whether wchar_t should always be 4 bytes in this case, so we better not use if for
assuming the size here.

Instead of relying on __STDC_ISO_10646__ add HAVE_WCHAR_H and SIZEOF_WCHAR_T macros.
With HAVE_WCHAR_H defined we assume wchar_t exists and wchar.h exists. With SIZEOF_WCHAR_T we
guard the parts where the size of wchar_t is assumed to be 4 (currently all of them).

Note that this doesn't make the collate tests pass under cygwin, they fail before and after this patch for me.

See !755 for related discussions.

93d8482384 build: Fix a typo in the test whether _NL_ABALTMON_n is supported
The correct spelling is "_NL_ABALTMON_n" rather than "_NL_ALTMON_n".
The typo made Meson build think that _NL_ABALTMON_n constants are
not supported which was totally wrong. This made g_date_time_format()
output incorrect abbreviated month names in some languages.
The old configure.ac script was correct here.

Bug introduced in commit be4f96b650.

Currently, there is no way to prevent tests from building using meson.
When cross-compiling, building the tests isn't necessary.

Instead, only build the tests on the following conditions:
1) If not cross-compiling.
2) If cross-compiling, and there is an exe wrapper.

4c038a27ff Check for /proc/self/cmdline
Instead of hardcoding /proc/self/cmdline use for __linux__ only,
do a configure-time test for it.

Specifically, this enables /proc/self/cmdline use on Cygwin.

The configure-time test is very primitive (just tests that the
file exists and that it's possible to read more than one byte from it),
relying on the testsuite for more extensive checks.

The test in the testsuite is modified to always run, even on platforms
where it isn't supposed to pass. If it fails there, the testing framework
skips it. If the test unexpectedly passes, that is reported too.

installed tests: Allow tests to set environment variables
It's necessary sometimes for installed tests to be able to run with a
custom environment. For example, the gsocketclient-slow test requires an
LD_PRELOADed library to provide a slow connect() (this is to be added in
a followup commit).

Introduce a variable `@env@` into the installed test template, which we
can override as necessary when generating `.test` files, to run tests
prefixed with `/usr/bin/env <LIST OF VARIABLES>`.

As the only test that requires this currently lives in `gio/tests/`, we
are only hooking this up for that directory right now. If other tests in
future require this treatment, then the support can be extended at that
point.

4e058a698a meson: Define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 on GNU/Linux if needed
armv5 Linux systems implement __sync_bool_compare_and_swap() and
friends by calling a function provided by the kernel. This is not
technically an atomic intrinsic, so gcc doesn't define
__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 in this case, but it's good
enough for us. Extend the current Android special case to cover
GNU/Linux too.

The possibilities are:

* __sync_foo detected and __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 predefined:
  calls to __atomic_foo or __sync_foo primitives are inlined into user
  code by gatomic.h

* __sync_foo detected but __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 not
  predefined: user code has an extern reference to g_atomic_foo(),
  which calls __atomic_foo or __sync_foo because we defined
  __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 when compiling GLib itself

* Windows: user code has an extern reference to g_atomic_foo(),
  which calls InterlockedFoo()

* !defined(G_ATOMIC_LOCK_FREE): user code has an extern reference to
  g_atomic_foo(), which emulates atomic operations with a mutex

295964a380 gutils: Check whether getauxval function exists
FreeBSD 12 adds a new header, sys/auxv.h, to declare a function, elf_aux_info,
for public use, which was considered an internal function in previous releases.
This new function provides similar functionality with glibc getauxval, which is
also declared in the same header, but their interfaces are not compatible. Since
the only usage of sys/auxv.h is in g_check_setuid and FreeBSD already has
issetugid to provide the required functionality, we fixes the compilation error
by adding a check for getauxval function to prevent g_check_setuid from calling
getauxval when sys/auxv.h is found but getauxval is not available.

64f789c6e2 meson: Always set G_MODULE_SUFFIX to so on macOS
This is what Autotools does, and it's what all consumers of the
GModule API expect. Without this change, people on macOS upgrading to
a GLib built with Meson will find that their plugins no longer load.

Projects that use Meson and the `g_module_build_path()` API such as
glib-networking should pass `name_suffix:` to `shared_module()` to
ensure that plugins continue to be called libfoo.so on macOS.

New GModule API will eventually be added to address this.

With autotools AC_FUNC_ALLOCA was used which defines HAVE_ALLOCA_H, HAVE_ALLOCA,
C_ALLOCA. meson tried to replicate that with has_function() but alloca can be a macro
and and is named _alloca under Windows. Since we require a working alloca anyway
and only need to know if the header exists replace AC_FUNC_ALLOCA with a simple
AC_CHECK_HEADERS.

There is still one user of HAVE_ALLOCA in the embedded gnulib, but since alloca is
always provided through galloca.h just force define HAVE_ALLOCA there and add a comment.

The docs were mentioning alloca as an example for cross compiling. Since that variable no
longer exists now replace it with another one.

7e6fb333f7 meson: define _FILE_OFFSET_BITS=64 for MinGW. See #1476
The autotools build set it by default and we use off_t in various places,
even on Windows. Also set it with the meson build to avoid any regressions.

Ideally we shouldn't use off_t and use 64bit capable API on Windows instead, so
we get large file support with MSVC as well.

631c3534b7 meson: use the new 'python' module instead of the 'python3' one. Closes #1455
The new python module, added with 0.46, works with Python 2 and 3 and
allows to pass a path for the interpreter to use, if the need arises.

Previously the meson build set PYTHON, used in the shebang line of
the scripts installed by glib, to the full path of the interpreter.
The new meson module doesn't expose that atm, but we should set it to
a executable name anyway, and not a full path.

194df27f5a gatomic: Tweak __atomic_load*() calls to work with -Wbad-function-cast
When compiling third-party projects with -Wbad-function-cast, the inline
g_atomic_pointer_get() implementation which uses C11 __atomic_load*()
calls on GCC was causing compilation errors like:

   error: cast from function call of type ‘long unsigned int’ to non-matching type ‘void *’

While we don’t want to compile all of GLib with -Wbad-function-cast, we
should support its headers being included in projects which do enable
that warning.

It doesn’t seem to be possible to cast away the warning (e.g. by casting
the function’s result through (void)), so we have to assign to an
intermediate integer of the right size first.

The same has to be done for the bool return value from
__sync_bool_compare_and_swap(). In that case, casting from bool to
gboolean raises a -Wbad-function-cast warning, since gboolean is
secretly int.

The atomic tests have been modified to enable -Wbad-function-cast to
catch regressions of this in future. The GLib build has conversely been
modified to set -Wno-bad-function-cast, just in case people have it set
in their environment CFLAGS.

61f54591ac gspawn: Optimize with posix_spawn codepath
When the amount of free memory on the system is somewhat low, gnome-shell
will sometimes fail to launch apps, reporting the error:
  fork(): Cannot allocate memory

fork() is failing here because while cloning the process virtual address
space, Linux worries that the thread being forked may end up COWing the
entire address space of the parent process (gnome-shell, which is
memory-hungry), and there is not enough free memory to permit that to
happen.

In this case we are simply calling fork() in order to quickly call exec(),
which will throw away the entirity of the duplicated VM, so we should
look for ways to avoid the overcommit check.

The well known solution to this is to use clone(CLONE_VM) or vfork(), which
completely avoids creating a new memory address space for the child.
However, that comes with a bunch of caveats and complications:

  https://gist.github.com/nicowilliams/a8a07b0fc75df05f684c23c18d7db234
  https://ewontfix.com/7/

In 2016, glibc's posix_spawn() was rewritten to use this approach
while also resolving the concerns.
https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=9ff72da471a509a8c19791efe469f47fa6977410

I experimented with a similar approach in glib, but it was not practical
because glibc has several items of important internal knowledge (such as
knowing which signals should be given special treatment because they are
NPTL implementation details) that are not cleanly exposed elsewhere.

Instead, this patch adapts the gspawn code to use posix_spawn() where
possible, which will reap the benefits of that implementation.
The posix_spawn API is more limited than the gspawn API though,
partly due to natural limitations of using CLONE_VM, so the posix_spawn
path is added as a separate codepath which is only executed when the
conditions are right. Callers such as gnome-shell will have to be modified
to meet these conditions, such as not having a child_setup function.

In addition to allowing for the gnome-shell "Cannot allocate memory"
failure to be avoided, this should result in a general speedup in this
area, because fork()'s behaviour of cloning the entire VM space
has a cost which is now avoided. posix_spawn() has also recently
been optimized on OpenSolaris as the most performant way to spawn
a child process.

c61f01f0ff build: Define MAJOR_IN_TYPES when major is defined in sys/types.h
Autoconf macro AC_HEADER_MAJOR doesn't define a macro in config.h when
major is defined in sys/types.h. This was not a problem because major
is assumed to be always available. However, commit aefffa3fbc
changes this assumption in order to fix build on systems without major,
which causes code using major to be disabled on systems putting major
in sys/types.h.

This commit defines a new macro MAJOR_IN_TYPES for both autotools and
meson builds to make major useful on these systems again.

cc.has_header checks whether a header exists without knowing whether it
can be used. This is a problem on FreeBSD because its malloc.h is a
header with an '#error' line which always throw compilation error. To
avoid false positive in the check result, we use cc.compiles to do a
full compilation test instead of cc.has_header which only does check
with preprocessor.

a7fefb0e4e g_check_setuid: implement using getauxval(AT_SECURE) with glibc
See commit 4c2928a544 for why checking AT_SECURE is preferable compared
to UID checks as currently done in the fallback case.

getauxval() was added with glibc 2.16

While glibc <2.19 didn't provide a way to differentiate a 0 return value from an error,
passing AT_SECURE should always succeed according to
https://sourceware.org/ml/libc-alpha/2014-07/msg00407.html
I've added an errno check anyway, to be on the safe side.
