Because the documentation is no longer built using gtk-doc.
Keep the old option around, but deprecated.

Currently, the introspection data for GLib and its sub-libraries is
generated by gobject-introspection, to avoid the cyclic dependency
between the two projects.
Since gobject-introspection is generally available on installed systems,
we can check for its presence, and generate the introspection data
directly from GLib.
This does introduce a cyclic dependency, which is why it's possible to
build GLib without introspection, then build gobject-introspection, and
finally rebuild GLib.
By having introspection data available during the GLib build, we can do
things like generating documentation; validating newly added API; and
close the loop between adding new API and it becoming available to non-C
consumers of the C ABI (i.e. language bindings).
The introspection API has lived out of tree far too long. It has the
same ABI guarantees as the rest of GLib, so it has no reason to be split
from the main library.
The gobject-introspection project can depend on libgirepository, and the
language bindings can drop the gobject-introspection-1.0 dependency.
This will be used in upcoming commits to allow the previously-hardcoded
`/run` path to be set at configure time.
Most people will not want to change it from `/run`, even when building
test builds, as otherwise interaction with system mounts and services
will not work.

It’s been broken since we ported to Meson and nobody has complained, so
let’s deprecate it this cycle and remove it in GLib ≥ 2.78.

In Debian-style multiarch (libdir = lib/x86_64-linux-gnu or similar),
Red-Hat-style multilib (libdir = lib64 or lib) and Arch-style multilib
(libdir = lib or lib32), we have to run a separate version of
gio-querymodules to discover 32- or 64-bit modules on x86. Installing
modules in the directory used for each word size needs to trigger
recompilation of the correct modules list.
Debian, Fedora and Arch currently all have patches to facilitate this:
Debian moves gio-querymodules into ${libdir}/glib-2.0 and provides a
compat symlink in ${bindir}, while Fedora and Arch rename one or both
of the gio-querymodules executables to give it a -32 or -64 suffix.
We can avoid the need for these patches by making this a build option.
Doing this upstream has the advantage that the pkg-config metadata for
each architecture points to the correct executable and is in sync with
reality.
I'm using Debian's installation scheme with a separate directory here,
because the word-size suffix used in Fedora and Arch only works for the
common case of 32- and 64-bit multilib, and does not cover scenarios
where there can be more than one ABI with the same word size, such as
multiarch cross-compilation or alternative ABIs like x32.
Now that we have this infrastructure, it's also convenient to use it for
glib-compile-schemas. This works with /usr/share, so it only needs to
be run for one architecture (typically the system's primary
architecture), but using /usr/bin/glib-compile-schemas for the trigger
would result in either primary and secondary architectures trying to
overwrite each other's /usr/bin/glib-compile-schemas binaries, or a
circular dependency (the GLib library would have to depend on a
common package that contains glib-compile-schemas, but
glib-compile-schemas depends on the GLib library). Installing a
glib-compile-schemas binary in an architecture-specific location
alongside each GLib library bypasses this problem.

iconv is complicated to look up. That complexity now resides in
Meson, since 0.60.0, via a `dependency('iconv')` lookup, so use that
instead.
No effort is made to support the old option for which type of iconv to
use. It was a false choice, because if only one was available, then
that's the only one you can use, and if both are available, the external
iconv shadows the builtin one and renders the builtin one unusable,
so there is still only one you can use.
This meant that when configuring glib with -Diconv=libc on systems that
had an external iconv, the configure check would detect a valid libc
iconv, try to use it, and then fail during the build because iconv.h
belongs to the external iconv and generates machine code using the
external iconv ABI, but fails to link to the iconv `find_library()`.
Meson handles this transparently.
libgamin was last released in 2007 and is dead
[upstream](https://gitlab.gnome.org/Archive/gamin). Distributions may
still ship it (although Fedora no longer does), but we want people to
use inotify on Linux since it’s actively supported.
BSDs use kqueue. Windows uses win32filemonitor.
FAM might still be used on some commercial Unix distributions, but there
are no contributors from those distributions, and certainly no CI for
them to prevent regressions.

This should maintain equivalent functionality, apart from that now you
have to pass `--force-fallback-for libpcre` to `meson configure` in
order to use the subproject; rather than specifying
`-Dinternal_pcre=true` to use the internal copy.
This also fixes#642, as the wrapdb copy of libpcre is version 8.37.

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.

In cases where performance are critical it can be useful to disable
checks and asserts. GStreamer has those options too, using the same name
and setting them yielding means we can set those options on the main
project (e.g. gst-build) and glib will inherit the same value when built
as subproject.
Instead of requiring the user to specify which option to use, which
they will not really know, nor should they need to know.
Search for each type of iconv (in the C library, as a separate
native library, as the GNU implementation) by default.

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.
gio-querymodules-wrapper.py is copied from glib-networking. This python
wrapper script is needed because meson.build cannot check for DESTDIR
env variable itself, unlike Makefile.am. It is used to update
giomodule.cache file when installing GIO modules like fam.
This allows building with posix threads on Windows. It is generally
better to use win32 threads implementation on Windows, but this option
can be used in case it causes issues, or for performance comparison for
example.

By default, only build man pages and gtk-doc if the build-deps were
found. To force-enable, pass -Dwith-docs=yes and -Dwith-man=yes.
Also use a foreach loop for man pages instead of listing them all
manually
