Instead of letting each directory to find its way to link with libdl,
it is easier to put the check in the top level, so its result can be
used by all directories.
It is a follow-up of https://gitlab.gnome.org/GNOME/glib/merge_requests/810.
Also set the Windows version to be 10 or newer when targeting UWP, since
the Windows 8 SDK does not have many of the APIs we need, such as
_beginthreadex.
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.
LoadLibrary() is not available when building for the Universal Windows
Platform, which is used for shipping apps to the Windows Store on all
devices (Windows Desktop, Windows Phone, Surface, XBox, etc).
Apps are not allowed to load arbitrary DLLs from the system. The only
DLLs they can load are those that are bundled with the app as assets.
LoadPackagedLibrary() can be used to access those assets by filename.
The function is meant to be a drop-in replacement for LoadLibrary(),
and the HANDLE returned can be treated the same as before.
Since out-of-source-tree builds are now used after switching to meson,
we don't need .gitignore files in the source directories to ignore
build artifacts.
This fixes build errors when doing a meson build after an autotools
build, because generated files such as gio/xdp-dbus.c won't show up in
a `git status`, or be removed by a `git clean -f`, and so it won't be
obvious that such files need to be removed for the meson build to
succeed.
So long, and thanks for everything. We’re a Meson-only shop now.
glib-2-58 will remain the last stable GLib release series which is
buildable using autotools.
We continue to install autoconf macros for autotools-using projects
which depend on GLib; they are stable API.

Turns out the fix in commit 93555577c wasn't enough, when using glib as
subproject and the parent project uses only libgio_dep, and include
<gi18n.h>, it won't find libintl.h because it's in the
include_directories of libglib_dep. Fix that by declaring dependencies
explicitly, which is the right thing to do since glib and gobject are
public dependencies of gio. That reflects what we do for the pkg-config
file as well.
When using glib as subproject we are forced to pass glib_dep,
gobject_dep and gio_dep to any build target. If we pass only gio_dep it
will missing include directory for glib and gobject.
-z nodelete breaks the libresourceplugin module usage in the resources.c
test, which expects to be able to unload it.
Make the Meson build match what the autotools build does: only pass
glib_link_flags to the headline libraries (glib-2.0, gio-2.0,
gobject-2.0, gthread-2.0, gmodule-2.0) and omit it from all other build
targets.

Properly define GLIB/GOBJECT_STATIC_COMPILATION when static build is enabled.
Use library() instead of shared_library() to allow selecting static builds.

When loading a module on win32, a blocking error dialog pops up whenever
the module could not be loaded. This is particularly annoying when
module loading failure is a harmless and expected event...
This patch temporarily disables these error dialogs from popping up.

This is a partial change of the previous work[0].
On 64 bit Android since android-23, 'handle = dlopen(NULL); dlsym(handle)'
doesn't work. Instead, only 'dlsym(RTLD_DEFAULT)' returns a valid pointer.
However, RTLD_DEFAULT is defined as '(void *) 0x0' on 64bit Android which
is usually used for invalid value so this patch allows the specific case.

Don't use it project-wide for building everything. Otherwise
symbols for shared modules won't be exposed, e.g. in the
resourceplugin used by the gio resource unit test.
Disable gio tests on Windows, fix .gitignore to not ignore
config.h.meson, and add more things to it.
Rename the library file naming and versioning to match what Autotools
outputs, e.g., libglib-2.0.so.0.5000.2 on Linux, libglib-2.0-0.dll and
glib-2.0-0.dll on Windows with MSVC.
Several more tiny fixes, more executables built and installed, install
pkg-config and m4 files, fix building of gobject tests.
Changes to gdbus-codegen to support out-of-tree builds without
environment variables set (which you can't in Meson). We now add the
build directory to the Python module search path.
On 64 bit Android this is #defined to 0, which is considered an invalid
library handle in all other cases. RTLD_DEFAULT is only supposed to be
used with dlsym() it seems, and the usage here was just an
"optimization" before.
By dlopen'ing NULL, we get the same on all 64 bit Android variants and it
actually works instead of erroring out. On 32 bit Android, dlopen() of
NULL unfortunately usually gives us something useless that finds no
symbols whatsoever.

For versions of GCC which support it (≥ 4), define G_MODULE_EXPORT as
__attribute__((visibility("default"))). This is normally a no-op, unless
compiling with -fvisibility=hidden, in which case it marks a symbol to
be publicly exported from the library, which is what G_MODULE_EXPORT is
for. Previously G_MODULE_EXPORT has only worked on Windows.
The compatibility check for whether the compiler supports
__attribute__((visibility)) is based on the __GNUC__ define, and is
similar to the check done in configure.ac for defining G_GNUC_INTERNAL.

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
We have a configure.ac check for lib.exe that attempts to enable
creation of .lib files for our 5 public libraries. That has been broken
for a long time for two reasons:
1) the Makefiles hardcode 'lib' instead of 'lib.exe'
2) we dropped generation of .def files quite some time ago (except for
in gthread where we have the two-symbol file under version control)
Add new rules for creating .def files from dumpbin.exe (which you should
have if you have lib.exe) and fix the .lib rules to use lib.exe.
Add a bit of $(AM_V_GEN) all around, as well.

Since we are no longer using sgml mode, using /* */ to
escape block comments inside examples does not work anymore.
Switch to using line comments with //
In Windows development environments that have it, <unistd.h> is mostly
just a wrapper around several other native headers (in particular,
<io.h>, which contains read(), close(), etc, and <process.h>, which
contains getpid()). But given that some Windows dev environments don't
have <unistd.h>, everything that uses those functions on Windows
already needed to include the correct Windows header as well, and so
there is never any point to including <unistd.h> on Windows.
Also, remove some <unistd.h> includes (and a few others) that were
unnecessary even on unix.

Remove workarounds for NeXTStep (last released in 1995), SunOS (1994),
HP-UX 9.x (1992) and 10.x (1995), OSF/1 / Digital UNIX / Tru64 UNIX
4.x (1999), and AIX 4.x (1999).
HP-UX 11 implements dlopen(), so dropping support for earlier versions
also lets us remove the HP-UX-specific gmodule-dld.

Since the initial addition of BeOS support in 1999, there has only
been one update to it (in 2005, and it wasn't even very big). GLib is
known to not currently build on Haiku (or presumably actual BeOS)
without additional patching, and the fact that there isn't a single
G_OS_BEOS check in gio/ is suspicious.
Additionally, other than the GModule implementation, all of the
existing G_OS_BEOS checks are either (a) "G_OS_UNIX || G_OS_BEOS", or
(b) random minor POSIXy tweaks (include this header file rather than
that one, etc), suggesting that if we were going to support Haiku, it
would probably be simpler to treat it as a special kind of G_OS_UNIX
(as we do with Mac OS X) rather than as its own completely different
thing.
So, kill G_OS_BEOS.
