Previously tests existed in two places,
`$top_srcdir/tests/sources.c` contained additional tests,
they have now been moved to `$top_srcdir/glib/tests/mainloop.c`
and `$top_srcdir/tests/sources.c` was deleted.

Notifying during object destruction is a dubious "feature": objects
might end up recreating a bunch of state just before clearing it;
language bindings might get spurious notifications during garbage
collection runs.
We freeze the notification queue before running the dispose() chain; if
the object was temporarily vivified during dispose, we thaw the
notification queue, otherwise we let the instance clear it when we
finalize it.

Previously tests existed in two places,
`$top_srcdir/tests/qsort-test.c` contained a similar test
to the one in `$top_srcdir/glib/tests/sort.c` called `test_sort_basic()`
The test for checking with zero elements was additional added to
`$top_srcdir/glib/tests/sort.c` and `$top_srcdir/tests/qsort-test.c`
was deleted.

Improve the performance of canonicalising filenames with many `..` or
`.` components, by modifying the path inline rather than calling
`memmove()`.

Fixes: #2541
Added `g_alloca0()` which wraps `g_alloca()` and initializes
allocated memory to zeroes.
Added `g_newa0()` which wraps `g_alloca0()` in a typesafe manner.
Refreshed and tweaked by Nishal Kulkarni.
The charset set in `CHARSET` overrides the charset after the `.` in any
`LC_*` category (set via the environment or `setlocale()`). This will
break many tests, but in particular it definitely breaks the
`/GDateTime/format_mixed/` tests which are specifically checking
different charsets being set for different `LC_*` categories.

Fixes: #2514
Users should probably never be setting this — instead, just add the
charset after a `.` in `LANGUAGE`/`LC_ALL`/`LC_*`/`LANG`.
I can’t find any reference (in `git log`, code comments, or man pages)
to this environment variable being standardised or documented or even
used anywhere outside GLib. Perhaps it should eventually be removed.
If anybody finds references as to why GLib checks `CHARSET`, this
comment can be updated in future.

De-duplicate g_nearest_pow() implementation and add some overflow protections to g_ptr_array_maybe_expand(), g_string_maybe_expand() and g_string_chunk_insert_len()
See merge request GNOME/glib!2368
If the new string's length plus the existing storage's length is
overflowing a gsize, we would previously memcpy() the string over the
bounds of the previous allocation.
Similarly if the string's size was bigger than G_MAXSIZE / 2 we would've
previously allocated 0 bytes.
Now instead create a new allocation that fits the string.
It might otherwise happen that the return value from g_nearest_pow()
does not fit into a guint, i.e. it might be G_MAXUINT + 1 if that fits
into a gsize.
This is sad, but GResolver has one member variable for historical
reasons, to implement the reload signal. Since it offers a global
singleton, we should make sure it's really safe to use from multiple
threads at once.
This call was needed once upon a time, when GResolver had subclasses
that presumably relied on this. Nowadays, we have only
GThreadedResolver, which does not need it. res_init() is dangerous
because it modifies global state, so let's get rid of it.
Currently `g_prgname` can be freed by `g_set_prgname()` while another
thread is holding a pointer to it.
We use GQuark when setting g_prgname so that string is never released once set.
Also added unit test, which checks if setting prgname in multi-threaded
program is safe.
Closes: #847
