`mock-resolver.c` is a mock implementation of `GResolver` used in the
`network-address` tests. It returns resolver results, and implements
timeouts, as directed by the test calling it.
In particular, it allows the IPv4 and IPv6 resolver results to be
returned using independent delays. This allows code paths which deal
with IPv4 and IPv6 results being returned at different times to be
tested, as the ‘Happy Eyeballs’ spec mandates various hard-coded
timeouts for returning the best results it can in a reasonable
timeframe.
Previously, `mock-resolver.c` implemented the timeouts by handling
`lookup_by_name()` in a `GTask` worker thread, and calling `g_usleep()`
for the timeout. This seemed to cause occasional CI failures, such as
https://gitlab.gnome.org/GNOME/glib/-/jobs/1843454, where a resolver
error would be returned rather than the expected results:
```
ok 52 /network-address/happy-eyeballs/ipv4-error-ipv6-first
\# GLib-GIO-DEBUG: IPv4 DNS error: IPv4 Broken
(/var/tmp/gitlab_runner/builds/Ff4WDDRj/0/GNOME/glib/_build/gio/tests/network-address:18428): GLib-GIO-DEBUG: 09:03:08.587: IPv4 DNS error: IPv4 Broken
Bail out! GLib-GIO:ERROR:../gio/tests/network-address.c:586:got_addr: assertion failed (error == NULL): IPv4 Broken (g-io-error-quark, 24)
stderr:
**
GLib-GIO:ERROR:../gio/tests/network-address.c:586:got_addr: assertion failed (error == NULL): IPv4 Broken (g-io-error-quark, 24)
```
While I’ve been unable to reproduce these failures locally, I suspect
they might be down to thread spawning occasionally taking long enough on
a CI runner to change the ordering of the timeouts, such that the ‘Happy
Eyeballs’ algorithm returns a different set of results from what the
test expects.
So, this commit rewrites part of `mock-resolver.c` to implement timeouts
in the main thread, rather than in a worker thread. That should
eliminate the delays in spawning threads, and should mean that the
timeout sources in `mock-resolver.c` are attached to the same
`GMainContext` as those from the ‘Happy Eyeballs’ algorithm which are
monitoring them, so a total order over the timeouts can be guaranteed.
Of course, I might be completely wrong since this is just a guess and I
can’t properly test it since I can’t reproduce the failure. Worth a try.

The test results weren’t being freed.
This makes the `network-address` test clean under memcheck for me.

If these struct members aren't available, we can be more like an

Rather than running them on each commit on `main`. This saves resources.
Given that Android API 28 and FreeBSD 13 jobs continue to be run on each
commit on `main`, this seems like an acceptable tradeoff. It’s very
unlikely that a regression will happen which affects the older systems
and *not* the newer systems. If it does, it will be caught within a week
by the scheduled job.

This clarifies the intent of the `branches@GNOME/glib` selector. It

As with a previous commit, `.only-default` does things which are
orthogonal to what `.build-linux` does, so it’s clearer and more
extensible for CI jobs to specify both in their top-level `extends`
statements, rather than relying on `.build-linux` to pull
`.only-default` in.
This introduces no functional changes.

`.build` and `.only-schedules` are orthogonal, and I want to use
`.only-schedules` together with `.cross-template` in future, which would
require creating more cross-product templates.
Avoid that by splitting `extends: .build-only-schedules` into
```
extends:
- .build
- .only-schedules
```
Multiple extends are supported by GitLab: https://docs.gitlab.com/ee/ci/yaml/#extends

The source needs to be removed from the `GMainContext` before being
unreffed, otherwise the main context and main loop will be kept around.

`g_environ_setenv()` and `g_environ_unsetenv()` were correctly returning
`NULL` when their preconditions failed (as the test is supposed to be
exercising). That overwrote the value of `env` without freeing it,
resulting in a leak.

Having compared the debug output, it doesn’t show anything unusual
happening that can’t already be seen from other output, for this test.
This is a partial revert of 8fd71dccc5. The debugging output it added to
other tests may still be useful.
