Rather than reallocating the string buffer a few times as more
components are added, use a default buffer size which should hopefully
accommodate most average URIs.
The buffer size is a guess and can be tweaked in future.
This has the advantage of no longer passing a potentially-`NULL`
`scheme` to `g_string_new()`, which should placate the static analysers,
which think that `g_string_new()` shouldn’t accept `NULL`.

`g_convert()` returns `NULL` iff it returns an error, but the static
analyser can’t quite work that out. Add an assertion to help.

Move the lcovrc file to the root of the project, so that it’s picked up
by Meson when running `ninja coverage` locally.
See https://github.com/mesonbuild/meson/issues/4628
This won’t affect the code coverage run on the CI, since that explicitly
used the lcovrc file already.

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:
```

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

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.
