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:

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.

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.

Currently we require explicitly specifying the port when configuring a
proxy server, which is seriously weird. I take the fact that nobody
reported a bug until 2022 to indicate that almost nobody is using
proxies. Whatever. Let's assume that if no port is provided, the default
port for the protocol should be used instead.
For example, you can now specify in GNOME settings that your proxy server
is https://example.com and it will work. Previously, you had to write
https://example.com:443. Yuck!
This was originally reported as GProxyResolver bug, but nothing is
actually wrong there. It's actually GProxyAddressEnumerator that gets
tripped up by URLs returned by GProxyResolver without a default port.
This breaks GSocketClient.
Fixing this requires exposing GUri's _default_scheme_port() function to
GIO. I considered copy/pasting it since it's not very much code, but I
figure the private call mechanism is probably not too expensive, and I
don't like code duplication.
Fixes#2832
This is true for socks://, socks4://, socks4a://, and socks5://. I could
list them individually and risk breaking in the future if socks6:// ever
exists, or test for "socks" and risk breaking if a future URL scheme
begins with "socks" but doesn't use port 1080. I picked the latter.
The compiler annotations are mainly useful for people using the symbols
directly.
To avoid getting compiler warnings for the GTypeValueTable definition
itself, we need to wrap the structure with
G_GNUC_BEGIN_IGNORE_DEPRECATIONS and G_GNUC_END_IGNORE_DEPRECATIONS.
The introspection scanner cannot deal very well with function pointers
into a plain structure. In order to document the various function
pointers in GTypeValueTable we need to create typed callbacks, and
use them to replace the anonymous function pointers inside the
structure. This not only allows us to properly document the function
pointers, but it also allows us to annotate the arguments and return
value of those function pointers.

For now, the function parse_trigraph() defined in gobject/glib-mkenums
script was not taking double-quotes characters into account:
>>> parse_trigraph('name="eek, a comma"')
{'name': '"eek', 'a': None}
This patch take double-quotes characters into account:
>>> parse_trigraph('name="eek, a comma"')
{'name': 'eek, a comma'}
Closes issue #65
Normally we don't really have emission hooks around, so try to allocate
only tiny array to contain a few of them and in case we exceed that limit,
we go back to use allocated ones.
We used to call this function as unlocked, with a node value that
could be invalid at the point of the call, so let's ensure that when
we call such function it's defined, and then reduce the access to the
signal node members when we're unlocked or after a lock/unlock operation
that may have changed it.
As per this, add more tests handling multiple signal hooks cases that we
did not cover before.
