Add a missing ifdef from gfileutils.c that is needed for O_BINARY.
The other option was to remove O_BINARY, but i left it there for
the sake of completeness, as this is what g_file_get_contents() uses.
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.
Check for RTLD_NEXT being present, and disable the gsocketclient-slow
test if it's absent, since the shlib dependency of that test requires
RTLD_NEXT to function.
This allows the testsuite to be built on Cygwin, which behaves
exactly like UNIX, but doesn't have RTLD_NEXT.
This macro was lost during meson migration. Set it again.
Also explain that Cygwin maintainers applied patches[0] to glib that
simply marked all G_PLATFORM_WIN32-protected code as !defined(G_WITH_CYGWIN),
i.e. they did not want that code to compile.
Instead of altering ifdef guards all over the place, we'll just
not define G_PLATFORM_WIN32 for Cygwin anymore.

In cross-compilation environments the runtime check isn't possible so it is up
to the builder to seed the cross file, but we can definitely state that strlcpy
doesn't exist with a build test.
Those lists were getting very long. We can’t quite entirely automate the
list generation since Meson doesn’t have a range() function, but we can
at least combine three of them into one.

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.
A lot of code cast function pointer to incorrect types. There is no
other way but silencing the warning. Follows an example of such cast:
glib/glist.c: In function ‘g_list_free_full’:
glib/glist.c:223:25: error: cast between incompatible function types from ‘GDestroyNotify’ {aka ‘void (*)(void *)’} to ‘void (*)(void *, void *)’ [-Werror=cast-function-type]
g_list_foreach (list, (GFunc) free_func, NULL);

It is not always needed to generate and install gmo files, for example
when building for Android or Windows that often doesn't have libintl to
use them anyway.
At least all GStreamer modules have this same option.
This is enough for most Debian buildds, including embedded devices
like mips and powerpcspe. It is not enough for hppa (PA-RISC), but that
architecture is so uniquely slow that it might make more sense to
special-case it downstream.

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

Closes: #1576
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.

Partial revert of commit a7a6449f4d.
Checking for the availability of m4 for installing m4 macro files
creates an implicit dependency on m4 even if GLib does not need it; this
prevents building GLib and then installing Autotools in order to build a
project that depends on GLib.
Closes#1520
We already set -Wformat=2, which implies -Wformat-security, so there’s
no need to test for and set -Wformat-security separately.
The test for -Wformat-security never worked anyway, since gcc complains
if it’s specified without also setting -Wformat to some value. The
complaint causes configure.ac/meson.build to assume the option doesn’t
work.
