`_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.

Fixes: #3039
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.
Helps: #3025
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.
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)`.

Add to script the new functions added in
commit 2368187e and commit e5ee6e14 which are:
signal_emitv_unlocked()
signal_emit_valist_unlocked()
so that the "<emit signal 'blabla'>" line keeps
showing after them.
It’s almost a complete waste of time at the moment. For several reasons,
jobs flakily fail on it more often than they succeed. It’s wasting
resources, slowing down development and making people quite frustrated.

Nobody has stepped up to deal with the test or CI runner flakiness, or
generally maintain this CI runner. If someone does care about preventing
regressions for GLib on macOS, and can put time into making the CI
reliable, then this commit can be reverted.

It’s fairly consistently timing out on macOS. Looking at the verbose
test output, it’s still making progress right up until when it times out
(i.e. it hasn’t hit a `GRecMutex` bug and hasn’t deadlocked), so it
seems that the test runner is just hopelessly overloaded/underpowered
for the number of threads and iterations we’re asking it to test.
Tone those numbers down for CI test runs then.

And dynamically allocate the arrays. This will allow the scale of the
test to be configured in the following commit, which will allow it to be
tweaked to not time out on slow CI runners.

Displaying the execution time will aid developers in understanding which
test cases are responsible for slow execution times. The test code is
already measuring the execution time for every test case, but is not
reporting that data anywhere accessible to developers running the tests.
The new code will print a TAP comment:
# slow test /the/test/path executed in NN.NN secs
for any test taking longer than 0.5 seconds to run.
Example new output format:

As a practical usage example, the meson log can be queried to find
slow tests project-wide:
$ grep 'slow test' build/meson-logs/testlog.txt | sort -n -k 7 -r | head

glib-compile-resources --dependency-file= currently generates a depfile
with rules that look like this:
foo.xml: resource1 resource2
This means that if any of the files listed in the GResource manifest
foo.xml change, rebuild foo.xml because foo.xml depends on those files.
This is not useful because the XML manifest is not expected to be a
generated dependency and even if it was, changes to the listed files
would not imply any need to regenerate the manifest. What we really do
need to regenerate is the C source file that is generated by
glib-compile-resources after processing the XML manifest and all the
resource files. That is, the rule should look like this:
foo.c: foo.xml resource1 resource2
as suggested by Hans Ulrich Niedermann in the issue report.
Fixes#2829
This is useful when writing similarly low-level code, and was always true
as implemented here; let's document it so that other codebases can rely
on it.
