gio: Rename gcontenttype.c to gcontenttype-fdo.c
This reflects its status as actually platform-dependent: it’s only built
on systems using the freedesktop.org content type system.

It makes the file naming match up with other platform-specific
implementations, such as `gcontenttype-win32.c` and
`gcontenttype-osx.m`.

A subsequent commit will introduce a platform-independent high level API
wrapper so that the introspection annotations from this file can be
reused between platforms.

ef73ce4f7f Introspection: Fix running g-ir-scanner 1.80.x+ on Windows
Since we are now building introspection files for GLib while building
GLib, so we want to make sure that we indeed load the freshly-built
DLLs when running g-ir-scanner, so we add the various needed subdirs
(and if needed, subprojects), to set the GI_EXTRA_BASE_DLL_DIRS
envvar so that g-ir-scanner will look for the newly-built GLib DLLs.

Ideally, upstream g-ir-scanner will need to be updated accordingly to do
something similar to what we are doing here, but this is needed until
the time that we require a g-ir-scanner that contains the update.

This will also fix the g-ir-scanner erroring out when there is no
pre-existing GLib on the system, as the needed DLLs are now found.

72d76922dc girepository: Fix static build under Windows
Properly define `GI_STATIC_COMPILATION` when static build is enabled.
Use `library()` instead of `shared_library()` to allow selecting static builds.

e862f34dd8 gmessages: introduce g_log_writer_default_set_debug_domains()
The problem is that resetting the environment of a
proccess is not safe, this is mentioned in the man
pages of the setenv, and also by the concept:
when we get a constant string returned by the getenv,
we need to be guaranteed that this string will exist
during all that time we are using it. While setting
the same env var to another value destroys this string
inside of libc.

Now looking at the should_drop_message(), we can see
that it just gets the environment on every call. Getting
the environment is safe, but however there's no safe way
to switch the logging domains selection: setenv can't be
used because of the reasons listed above.

That is why g_log_writer_default_set_debug_domains() is
needed: it's just a safe replacement for the setenv in this case.

Now should_drop_message() still reads the environment, but
does so only on the first call, after that the domains are
stored internally, and can only be changed by
g_log_writer_default_set_debug_domains().

This also means that now resetting G_MESSAGES_DEBUG env
var in runtime has no effect. But in any case this is not
what the user should do, because resetting the environment
in runtime is not correct.

89b0c1b304 glib.supp: Allow definite leaks of util dir paths
These are one-time leaks, and happen if the util dir paths are built via
these code paths, and then subsequently overwritten using
`g_set_user_dirs()` (typically as part of a unit test).

The additions to `glib.supp` correspond to the `g_ignore_leak()` calls
in `gutils.c`. Unfortunately `g_ignore_leak()` only affects asan, not
valgrind.

ab732692a0 tools: Add script to create UAC manifests for Windows
This is copied from the GTK source tree to put into our builds so that
we can generate a manifest file to pacify UAC on Windows for 32-bit
builds, as UAC will kill any 32-bit processes that it believes will
be an installer or will alter the system in any ways.

This will be used to fix running the custom-dispatch test program on
32-bit Windows builds.

fcad56e313 meson: Add glib_valgrind_suppressions variable to glib pkg-config file
Various projects are running tests under valgrind, and they are using
the GLib suppresions to avoid false-positive results.

While this is stored in a well-known path for some years, and easy to
figure out from the GLib prefix, it's better to expose it through a
proper pkgconfig variable so that it's easy to get it from any build
system.

f520066563 gutils: Add a private API to unset the cached temporary directory
We may need to avoid using a cached temp directory for testing purposes,
so let's provide an internal API to perform such task.

This implies removing GOnce and going with mutex-based version, but
that's still using atomic logic in most unix implementations anyways.

dcfc9f689e Fix symbol visibility macros on Windows
There is currently no `dllimport` attribute on any of our function,
which prevents MSVC to optimize function calls.

To fix that issue, we need to redeclare all our visibility macros for
each of our libraries, because when compiling e.g. GIO code, we need
dllimport in GLIB headers and dllexport in GIO headers. That means they
cannot use the same GLIB_AVAILABLE_* macro.

Since that's a lot of boilerplate to copy/paste after each version bump,
this MR generate all those macros using a python script.

Also simplify the meson side by using `gnu_symbol_visibility : 'hidden'`
keyword argument instead of passing the cflag manually.

This leaves only API index to add manually into glib-docs.xml when
bumping GLib version. That file cannot be generated because Meson does
not allow passing a buit file to gnome.gtkdoc()'s main_xml kwarg
unfortunately.

505755e4d2 glib.supp: Ignore gutils leaks for user and system dirs
These leaks happens "by design" in case that the private API
g_set_user_dirs() is used to replace directories during some tests.
And we've to leak the previously set values (if any) not to free strings
that may be used by other user code before.

In fact we're already ignoring LSAN reports for the very same reason
here.

We could create a private suppression file too, but I don't think we've to
bother with that, given that user code should never hit this path
anyways.

It's the only leak we have, sooo:

a1c78d63ef meson: Set install_tag on all tools
Those tools are not needed at runtime for typical applications,
distributions typically package them separately.

This makes `meson install --tag runtime` skip installation of those
tools. Omitting `--tag` argument will still install them, as well as
with `--tag bin,bin-devel`.
