This introduces no functional changes, but reworks the array indexing so
that scan-build has a better idea about the array bounds. This squashes
the scan-build warning:
```
../../../../source/glib/glib/gdatetime.c:2292:20: warning: The left operand of '>=' is a garbage value [core.UndefinedBinaryOperatorResult]
if (days [i] >= day_of_year)

This will probably make no functional difference, but will squash two
warnings from scan-build:
```
../../../../source/glib/gio/gsocket.c:503:14: warning: Assigned value is garbage or undefined [core.uninitialized.Assign]
family = address.storage.ss_family;

```
It seems like a reasonable thing to warn about. Initialising the full
union to zero should avoid any possibility of undefined behaviour like
that.

This is a valid situation which can occur if the preceding
`g_main_context_prepare()` call returns `FALSE` and doesn’t set
`max_priority`.

Tested using:
```sh
touch ~/foo
gio set ~/foo -t bytestring user::test "\x00\x00"

(it doesn’t matter that this fails; the bytestring is still decoded)

These `memcpy()` calls only happen if `g_inet_address_get_family(group)
== G_SOCKET_FAMILY_IPV4`, so the assertions should never fail.
It’s helpful for understanding the code, and for static analysis, to add
the assertions though.

Remove unused tests/timelooop.c and tests/timeloop-basic.c because
these programs are manual performance tests which are no more relevant
for glib. They were used for the writing of GMainLoop but since then
they haven't not much been used in 22 years, it is safe to remove them.
Helps issue #1434
Inspired by https://gitlab.gnome.org/GNOME/glib/-/issues/2638.
This requires moving the tests to subprocesses, so that
`g_log_set_writer_func()` is only called once per process.
It also adds a test for the new error.

When I enabled unix socketpair test on win32, I left the existing
g_close(fds[1]), but _g_win32_socketpair() returns native sockets
descriptors that must be closed with closesocket() on win32.
Let GSocket handle the socket pair cleanup.

As noted by Charlie Barto: "both mingw64 and msvc define _WIN64 in
64-bit mode, and both are LLP64, and both have struct _stat64 defined
the same way."

The pipe must be closed, or the child PID watch doesn't get triggered.
We should remove the message callback source on EOF, as EOF during main
loop run will reach a bad assert in the callback.

...for certain Windows locales, since the formats accepted for
g_date_set_parse() will vary depending on the current system locale. For
instance, g_date_set_parse(gdate, "dd/mm/yy") is accepted on locales such
as zh-HK (Chinese (Hong Kong SAR)) but is rejected on zh-TW (Chinese
(Taiwan)).
One can tell from the "date format" settings in the Windows system
control panel whether there is a "dd/MM/YYYY" or "dd/MM/YY" option from the
drop-down list of date formats to display for the locale, which will indicate
whether g_date_set_parse(gdate, "dd/mm/yy") is accepted, which is true for
zh-HK but is not true for zh-TW.
If g_date_set_parse(gdate, "dd/mm/yy") is not accepted, try again with
g_date_set_parse(gdate, "yy/mm/dd") thereafter for the 2-digit-year tests.
