Commit 7678b107 seems to have left the GHashTable pretty printer with an
off-by-one error, skipping the first key it encounters and printing an
extra garbage key/value pair instead. This fixes that by moving an
increment to the end of a loop rather than the beginning.
This ensures that when running many instances of the test in parallel,
they don’t collide in the same current directory, and hence spuriously
fail. This can happen when writing `out.xbel`, for example.

In general, we should aim to always check a `GError` before checking a
boolean, since the error message from the `GError` gives us a lot more
information about failure, which helps with debugging.

The time handling was assuming that the test would complete in the same
second as it started, which was not always true.

When choosing the type to base `size_t` on, check the compatibility of
passing pointers, as well as the width of the type, to avoid compiler
warnings in future.
For now, the code to do the checks is fairly ugly due to limitations in
Meson. In particular, the new checks are limited to gcc and clang (other
compilers will behave as before), and they are all duplicated. See the
comments in the code for links to Meson improvement requests.

Similar to 3837b83f, glibc memcmp is declared with the first two
arguments annotated as non-null via an attribute, which results in the
undefined behaviour sanitizer considering it to be UB to pass a null
pointer there (even if we are comparing 0 bytes, and hence not actually
dereferencing the pointer).
This shows up in /gvariant/serialiser/children when run with the
undefined behaviour sanitizer.

Tools like this should be configurable in a cross or native file. In
particular, if we are cross-compiling (with an executable wrapper like
qemu-arm), the build system ld is not necessarily able to manipulate
host system objects.

Otherwise we'll never test the EXTERNAL-only mode, because that relies
on testing the private macros
G_CREDENTIALS_UNIX_CREDENTIALS_MESSAGE_SUPPORTED and
G_CREDENTIALS_SOCKET_GET_CREDENTIALS_SUPPORTED.

This bypasses any issues we might have with containers where IPv6 is
returned by name resolution (particularly since GNOME/glib!616) but
doesn't necessarily actually work.
This comes at a minor test-coverage cost: we don't test GDBusServer's
default behaviour when told to listen on "tcp:" or "nonce-tcp:", and
on systems where IPv6 is available, we don't test it. If we want to
do those, we should perhaps do them in separate tests, and disable
those tests when binding to ::1 doesn't work.

kdeinit5 overwrites argv, which in turn results in /proc/self/cmdline
being overwritten. It seems that this is done in a way that does not
necessarily guarantee that /proc/self/cmdline will end up NUL-terminated.
However, g_file_get_contents() is documented to fill a buffer of size
len + 1, where buffer[len] == '\0', even if the file's actual contents
(from buffer[0] to buffer[len-1] inclusive) did not include a NUL;
so we can safely relax this assertion slightly.

Whitelist a safe set of characters for use in header guards instead of
maintaining a (growing) blacklist.
The whitelist is intentionally short since reading up on all
peculiarities of the C and C++ standard for identifiers is not my idea
of fun. :)

Change a condition from one to an equivalent one to shut up a
`scan-build` warning about potentially dereferencing a `NULL` value.
This introduces no functional changes, as it’s not actually possible to
dereference a `NULL` value here (but `scan-build` can’t link the
nullability of `error` to the nullability of `result`).

This avoids failure to listen on the given address on non-Linux Unix
kernels, where abstract sockets do not exist and so unix:tmpdir is
equivalent to unix:dir.
To avoid bugs like this one recurring, run most of these tests using
the unix:dir address type, where Linux is equivalent to other Unix
kernels; just do one unix:tmpdir test, to check that we still
interoperate with libdbus when using abstract sockets on Linux.

Previously, we used unix:tmpdir, except in tests that verify that a
particular address type works (notably unix:dir). Now we use unix:dir
most of the time, and unix:tmpdir gets its own test instead.
This helps to ensure that the tests continue to work on non-Linux Unix
kernels, where abstract sockets do not exist and so unix:tmpdir is
equivalent to unix:dir, even in the common case where the developer has
only tried the test on Linux.

Otherwise, since GNOME/glib!1193, the listening socket won't be deleted,
and if we are not using abstract sockets (for example on *BSD), g_rmdir
will fail with ENOTEMPTY.
