We relied on g_cclosure_marshal_generic() to easily generate signal
marshallers, but this relies on inspecting each parameter type with ffi
and this implies a performance hit, other than breaking the stack-frame
unwinder used by Linux perf and so by sysprof.
Given that we know the types we work on, it's easy enough to generate
the marshallers ourself.

For some reason, `time_t` is defined as being 32 bits wide on that
platform, which causes truncation of the timestamps from `struct stat`.
Avoid that problem by consistently using a 64-bit return value from the
`struct stat` accessors.

UAC will terminate this test program from running in 32-bit x86 builds as
it believes that it will alter Windows. In order to make this run, we
create a manifest file for 32-bit Windows builds in order to tell UAC
that this program should not need admin privileges.
This will allow the entire test suite for GLib to run on 32-bit Windows
builds.
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.
We were using emit_by_name which implies looking up for the signal name,
while the generated code can easily remember the signal ID and use it
instead, allowing direct access to the signal emission.
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.

`_g_stat_has_field (statbuf, G_LOCAL_FILE_STAT_FIELD_ATIME)` will always
return `TRUE` on Windows (since it uses a basic `struct stat`), so the
platform-inspecific code is equivalent to the Windows-specific code.

`GLocalFileStat` is a platform-specific abstraction around `struct stat`
or `struct statx`. If `struct statx` is available, it will use that by
preference as it has more features.
`glocalfileinfo.c` was, in some places, incorrectly accessing the fields
of `GLocalFileStat` directly rather than through its `_g_stat_*()`
getters. While it correctly accounted for the platform-specific
differences between `st_mtimensec` and `st_mtim.tv_nsec`, it hadn’t been
updated to deal with `stx_mtime`.
On Android, `st_mtimensec` is defined as a fallback for
`st_mtim.tv_nsec` (even though it doesn’t need to be). This caused GLib
to take the `st_mtimensec` code path rather than the `stx_mtime` code
path, and hence try to dereference `st_mtim` in a `struct statx`.
Fix that by correctly using the `_g_stat_*()` getters consistently.

To match the current widespread usage.
We can’t automatically append a colon to the group description, as that
would interact badly with translation of the string.

Fixes: #3007
Using `allow_fallback: false` on the first check for libpcre
was unnecessary, as `required: false` already disables using
fallbacks. `allow_fallback: false` meant that
`--force-fallback-for` couldn’t work. This commit fixes that.
Also allow the fallback libpcre to be built statically so it
can be linked into GLib.

This was originally removed in !2734 but still appears to be required for
some MinGW setups, such as the `x86_64-w64-mingw32.static` target in
[mxe](https://github.com/mxe/mxe).
Currently, this configuration fails the libintl internal assert on line
2128, as on this platform `ngettext()` is only found inside libiconv.
This commit will look up iconv potentially twice, once as `libiconv` and
potentially once as `libintl_iconv`. This is what the code did before
!2734 landed, so it’s known to work reliably on a number of platforms.
Just in case anyone tries to look it up using `find_program()` in a
`meson.build` in GLib (or a project pulling GLib in as a subproject) in
future.

The code to test that `g_usleep(0)` returns immediately assumes that
`g_usleep(1)` always takes longer, but that’s not necessarily always the
case. Even if no sleeping happens, the function call for `g_usleep(0)`
could get descheduled and take longer than normal.
This results in occasional failures like this one:
```
GLib:ERROR:../glib/tests/timer.c:367:test_usleep_with_zero_wait: assertion failed (elapsed0 <= elapsed1): (0.000206 <= 0.000202)
```
(Source: https://gitlab.gnome.org/GNOME/glib/-/jobs/2898468)
I can’t think of a suitable invariant comparison which can be done with
the timers, but running the comparison 10 times and allowing it to fail
once should work. A probabilistic test of `g_usleep(0)`.
