Now that the reference documentation uses gi-docgen, it's more
troublesome to generate in less standard build scenarios like
cross-compiling.
In distributions like Debian, reference documentation is generally
packaged separately (in libglib2.0-doc in Debian's case), but man pages
are generally packaged alongside the executables themselves (in the
libglib2.0-bin and libglib2.0-dev-bin packages, in Debian's case). We
can exclude the reference documentation when cross-compiling, but ideally
we would like the man pages to still be built, so that a cross-compiled
libglib2.0-bin or libglib2.0-dev-bin package has the same content as a
native build.

They are now installed to (e.g.)
`${prefix}/share/doc/glib-2.0/{glib,gmodule,gobject,gio}/index.html`.
We might want to drop one level of nesting out of that, but for the
moment I thought I’d keep it in so we can disambiguate by installed
major version.

So they are consistent with the way we’re building man pages in other
projects, and because some people are allergic to XML.
This changes the build-time dependencies from `xsltproc` to `rst2man`,
and also takes the opportunity to change the `-Dman` Meson option from a
boolean to a feature (so you should use `-Dman-pages={enabled,disabled}`
now, rather than `-Dman={true,false}`).

This is a variant of `g_test_trap_subprocess()` which allows the
environment for the child process to be specified. This is quite useful
when you want to test code which reads environment variables, as it’s
not safe to set those after the start of `main()`.
This will be useful within and outwith GLib for testing such code.

The GIR files are now built by GLib itself, so they will be in the build
directories of each sub-library, except for GLib-2.0 which is built
alongside GObject-2.0.
On CHERI-enabled systems we use uintptr_t as the underlying storage for
GType and therefore casting to gsize strips the upper bits from a pointer.
Fix this by casting via uintptr_t instead and introduce a new set of
macros to convert between GType and pointers.
It needs to be in a separate page because there isn’t actually a
`GFileAttribute` type.

Gate the API reference on the availability of the introspection data as
well, so we don't accidentally try and generate the documentation
without a description of our API.
g_strv_builder_take() allows to transfer ownership of the passed in
string.
This can be useful to avoid additional allocations when using functions
that transfer ownership to the caller like g_strdup_printf().
The testcase uses g_strv_builder_take and g_strv_builder_add to demo
that calls can be mixed.
This copies the test code inline into the Markdown, which means it could
diverge from the test code which is compiled and run as part of the
tests. That needs improving, but that can happen in a subsequent commit.

I'm not aware of any platforms where this is a problem in practice, but
it's definitely nonportable and doesn't hurt to document it.
I wonder about CHERI....
These functions can be used to initalize pointer-type variables rather
than a gsize. This is required to support CHERI-enabled platforms where
gsize cannot be used to store pointers. Follow-up changes will migrate
the uses of g_once_init that store pointers to the new API

The `GTK_USE_PORTAL` environment variable has started to be misused by
users, which is causing deployment issues (such as portal services
themselves ending up being forced to use portals, which is never going
to work).
Try and sidestep users’ broken configurations by renaming the
environment variable, and also separating it from the old GTK
environment variable, since the GLib one affects a lot more processes.
This environment variable is meant to be used for
debugging and development, and never in production.
GTK already renamed their environment variable in
https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/4829, so keeping the
`GTK_USE_PORTAL` name in GLib doesn’t make sense anyway.

Fixes: #3107
This reverts commit 252bbcd207.
After further discussion in !3511, we’ve decided that there are risks
associated with this change, and it’s not the best way of addressing the
original problem.
The original motivation for the change turned out to be that
`-mms-bitfields` was not handled by `windres`, which was receiving it
from `pkg-config --cflags glib-2.0` in some projects. However, if
`windres` is claiming to accept CFLAGS then it should accept (and
ignore) `-mms-bitfields`, since the `-m` family of options are defined
in `man gcc`, just like `-I`, `-D`, etc.
There is some question that there might still be third party projects
which are built with an old enough compiler that `-mms-bitfields` is not
the compiler default. For that reason, we should either still continue
to specify `-mms-bitfields` in the `.pc` file, or add a test to assert
that third party projects are always compiled with `-mms-bitfields` set.
But adding a new test for all third-party compilations is risky (if we
get it wrong, things will break; and it’s a test which may behave
differently on different platforms), so it seems safer to just keep
`-mms-bitfields` in `.pc` for now.
Once all compilers which we require specify `-mms-bitfields` by default,
we can finally drop this flag (without adding a test for third-party
compilations).
See: https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3511
This documents the practices that I’ve been trying to follow for the
last few years for managing GLib issues and merge requests, and why they
seem to work well enough.
