If proxy-libintl has already been configured before we get to glib, we
will pick that up in dependency('intl'), which then does compiler
checks on it. This was written to assume that the first check will not
find a subproject for libintl, so force it with allow_fallback: false.
Also update the proxy-libintl wrap file and get rid of the explicit
subproject() call.

This is in preparation for porting `GRegex` to libpcre2, which is
happening in !2529. It’s a big port, though, and specially rebuilding
the CI images to add libpcre2 for it is a pain.
Add libpcre2, and then !2529 can drop the old libpcre dependencies when
the port lands.

Rather than carrying the copylib around inside GLib, which is a pain to
synchronise and affects our code coverage statistics.
This requires updating the CI images to cache the new subproject,
including updating the `cache-subprojects.sh` script to pull in git
submodules.
It also requires adding `gioenumtypes_dep` to be added to the
dependencies list of `libgio`, since it needs to be build before GVDB as
it’s pulled in by the GIO headers which GVDB includes.

Sysprof recently cleaned up it's build configuration options. This is
perhaps a good time to update GLib to point at an updated commit'ish and
use the new options.
If now is not a good time to do the update, that is completely fine, but
I wanted to give you a turn-key MR nonetheless.
Recently wrapdb updated pcre from 8.37 (released in 2015!) to the
current 8.45 release. There have been several security fixes between
those releases and currently a buffer overflow is being flagged by
ostree's oss-fuzz project where pcre is installed via wrapdb.
This change was generated by `meson wrap update pcre`.
Glib cannot be built statically on Windows because glib, gobject and gio
modules need to perform specific initialization when DLL are loaded and
cleanup when unloaded. Those initializations and cleanups are performed
using the DllMain function which is not called with static builds.
Issue is known for a while and solutions were already proposed but never
merged (see: https://gitlab.gnome.org/GNOME/glib/-/issues/692). Last
patch is from version 2.36.x and since then the
"constructor/destructor" mechanism has been implemented and used in
other part of the system.
This patch takes back the old idea and updates it to the last version of
glib to allow static compilation on Windows.
WARNING: because DllMain doesn't exist anymore in static compilation
mode, there is no easy way of knowing when a Windows thread finishes.
This patch implements a workaround for glib threads created by calling
g_thread_new(), so all glib threads created through glib API will behave
exactly the same way in static and dynamic compilation modes.
Unfortunately, Windows threads created by using CreateThread() or
_beginthread/ex() will not work with glib TLS functions. If users need
absolutely to use a thread NOT created with glib API under Windows and
in static compilation mode, they should not use glib functions within
their thread or they may encounter memory leaks when the thread finishes.
This should not be an issue as users should use exclusively the glib API
to manipulate threads in order to be cross-platform compatible and this
would be very unlikely and cumbersome that they may mix up Windows native
threads API with glib one.
Closes#692
It is exactly the same wrap as the one in WrapDB but with a different
name. That fix error when multiple projects uses pcre and they don't
have the same wrap name:
meson.build:1:0: ERROR: Multiple wrap files provide 'libpcre' dependency: pcre.wrap and libpcre.wrap
0.2 was just tagged, which includes a commit from 2018 that fixes a
meson warning which caused the project to fail to build on Windows with
--fatal-meson-warnings enabled.
This is from the wrapdb, at version 8.37-2. This version includes
changes needed for the subproject to work correctly in GLib: enabled
Unicode support. Earlier wrap versions won’t work.

One of the points of subprojects is to allow building against a version
of a dependency that the project has been tested against, so don’t try
and build against gtk-doc master. Building against master is actually
currently fine, but is a slight risk. Making this change also removes
one more instance of `master` from `git grep master` results, which
helps #2348.

Use the depth= argument from Meson 0.52 to limit the clone depth of
subprojects to 1. This should make the CI images a little smaller, and
reduce the bandwidth required to build them (although that’s not so
important because it only happens once every few months).
Similarly, only clone to a depth of 1 in `cache-subprojects.sh`, which
is run once every few months.

Add some internal wrappers around sysprof tracing, so that it can be
used throughout GLib without exposing all the details of sysprof
internally.
This adds an optional dependency on `libsysprof-capture-4`. sysprof
support is disabled without it.
This depends on the GLib dependency of `libsysprof-capture` being
dropped in https://gitlab.gnome.org/GNOME/sysprof/-/merge_requests/30,
which has bumped the soname of `libsysprof-capture` and added subproject
support.
The next few commits will add marks that trace out each `GMainContext`
iteration and each `GSource` `check`/`prepare`/`dispatch` call.

Now that we require Meson 0.52 to build the doc, we can also pull
gtk-doc as subproject when missing from the system. This requires
to pull gtk-doc master because needed changes there haven't been release
yet.
This should fix our CI, which is currently failing on any system which
requires using the zlib subproject (typically VS systems) as wrapdb is
down. Work around that by pointing our wrap file at the underlying
github hosting instead.
See https://github.com/mesonbuild/meson/issues/6446#issuecomment-574241715
This can be reverted when wrapdb is working again.

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.
