`g_app_info_launch_default_for_uri_async()` has already returned by this
point, so waiting a long time is not really going to help.
Wait for 3× as long as the successful case took, which should allow for
long enough to catch true negatives, with a bit of variance.
On my system, this means waiting for about 14ms, rather than the 100ms
which this previous slept for. This speeds the test up by about 5%.

Given that it can be computed using an error-prone strings comparisons it
is better to provide a variable everywhere, so that we don't have the
risk of comparing values that are always false.
We have tests that are failing in some environments, but it's
difficult to handle them because:
- for some environments we just allow all the tests to fail: DANGEROUS
- when we don't allow failures we have flacky tests: A CI pain
So, to avoid this and ensure that:
- New failing tests are tracked in all platforms
- gitlab integration on tests reports is working
- coverage is reported also for failing tests
Add support for `can_fail` keyword on tests that would mark the test as
part of the `failing` test suite.
Not adding the suite directly when defining the tests as this is
definitely simpler and allows to define conditions more clearly (see next
commits).
Now, add a default test setup that does not run the failing and flaky tests
by default (not to bother distributors with testing well-known issues) and
eventually run all the tests in CI:
- Non-flaky tests cannot fail in all platforms
- Failing and Flaky tests can fail
In both cases we save the test reports so that gitlab integration is
preserved.
We have gnulib warnings in windows under clang:
../glib/gnulib/vasnprintf.c:2429:21: warning: variable 'flags' set but not
used [-Wunused-but-set-variable]

C99 does not actually guarantee that the platform has 8-, 16-, 32- and
64-bit types, but it does guarantee that if the platform has them, then
(u)intN_t are defined to be examples of those types.
GLib goes beyond what C99 guarantees, and requires 8-, 16-, 32- and
64-bit types; combining that with C99's requirements means we can
assume that int8_t, uint64_t, etc. all exist.
Unfortunately, we cannot guarantee that GLib and the C99 toolchain have
chosen the *same* fixed-size type: for example, on a typical ILP32
or LLP64 platform like Windows or 32-bit Linux, each 32-bit type could
either be int or long, while on a LP64 platform like 64-bit Linux,
each 64-bit type could either be long or long long. The in-memory
representation is the same either way, but the choice of underlying type
matters when building printf format strings or issuing compiler warnings.
As a result, we can't just typedef gint32 as int32_t and so on.

The important thing here is that we can't arbitrarily mix these, even if
they will often have the same in-memory representation.

These have a status similar to size_t: they're Standard C types and
straightforward to use in portable code this decade, but we can't
guarantee that we have chosen the same underlying type that the platform
uses.

This is similar to the relationship between gsize and size_t, except
that size_t is a Standard C type but ssize_t is platform-specific
(specifically, ssize_t is a POSIX type, and on Windows the equivalent
is SSIZE_T), making it more awkward to use in portable code. As a
result, continuing to use gssize is more useful than continuing to use
gsize.

We have chosen the underlying type that implements gsize to be the same
size as the standard C89 size_t (the top-level meson.build sets this up).
Unfortunately, we cannot guarantee that GLib and the C toolchain have
chosen the *same* fixed-size type: for example, on a typical ILP32
platform like 32-bit Windows or Linux, each of gsize and size_t
can either be int or long, while on a LP64 platform like 64-bit Linux,
each could either be long or long long. meson.build tries to choose the
same type to reduce compiler warnings, but it can only do this if the
compiler implements `-Werror`.
The in-memory representation is the same either way, but the choice of
underlying type matters when building printf format strings or issuing
compiler warnings, and can affect the C++ ABI of GLib-based software.
As a result, we can't just typedef gsize as size_t.
I've expanded the doc-comment to say a bit more about the implications
of the different types here, so that I can point to it from the
doc-comments of other types without repeating myself too much.

G_MODULE_SUFFIX is deprecated now because you will get the wrong
results using it most of the time:
1. The suffix on macOS is usually 'dylib', but it's 'so' when using
Autotools, so there's no way to get the suffix correct using
a pre-processor macro.
2. Prefixes also vary in a platform-specific way. You may or may not have
a 'lib' prefix for the name on Windows and on Cygwin the prefix is
'cyg'.
3. The library name itself can vary per platform. For instance, you may
want to load foo-1.dll on Windows and libfoo.1.dylib on macOS. This
is for libraries, not modules, but that is still a use-case that
people use the GModule API for.
g_module_build_path() does take care of (2) on Cygwin, but it
fundamentally cannot handle the possibility of multiple options for
the module name, since it does not do any I/O. Hence, it is also
deprecated.
Instead, g_module_open() has been improved so that it takes care of
all this by searching the filesystem for combinations of possible
suffixes and prefixes on each platform. Along the way, the
documentation for it was also improved to make it clearer what it
does.

In principle we could script this so that each max-version.c is compiled
26 times, once per possible MAX_VERSION, but I haven't implemented
that here: just pinning to the oldest possible version is sufficient to
reproduce #2796.
These aren't included in the installed-tests, since they don't really
do anything at runtime (the important thing is that they compile
without warnings).
Reproduces: #2796
