The size of stat depends on various macros on Windows which leads to
the problem of size mismatches when glib is built with a different configuration
than a program using it.
For example the autotools build defaults to _FILE_OFFSET_BITS=64 and a program
not defining _FILE_OFFSET_BITS will allocate a too small struct on the stack,
leading to stack corruption when glib writes to it.
To make the size the user sees always match the default mingw build define GStatBuf
as _stat64 (same as _FILE_OFFSET_BITS=64) under mingw+64bit.
Some of the test vectors don’t specify a timezone, so the local one is
used; the comparisons to the expected results (which are in UTC) then
fail.

When calculating the value of a timezone offset, ensure that any offsets
done with negative numbers are done in a signed integer.

token_stream_prepare() was over-reading at the start of bytestring
literals (`b'blah'`).
Add tests for that, and for some other situations regarding bytestring
literal parsing, in order to try and get full branch coverage of that
bit of code.

The token_stream_peek() functions were not doing any bounds checking, so
could potentially read 1 byte off the end of the input blob. This was
never noticed, since the input stream is almost always a nul-terminated
string. However, g_variant_parse() does allow non-nul-terminated strings
to be used with a @limit parameter, and the bugs become apparent under
valgrind if that parameter is used.
This includes modifications to the test cases to cover the
non-nul-terminated case.

These come from looking at the code coverage data. We should now have
full branch coverage of the ISO 8601 parser.

It never worked; we’ve always parsed the year with strtoul() (unsigned).
While negative years are supported by the ISO 8601 standard, they can
only be used by mutual agreement of the two parties interchanging data.
Moreover, they are not supported by GTimeVal, which is what we’re
filling with the results.

The code was previously doing a few bits of arithmetic without checking
whether they would overflow, and hence not validating the date/time it
was parsing very strictly.
The parser is now not 100% strict, but should avoid any arithmetic
overflows which would cause an invalid result to be returned even though
g_time_val_from_iso8601() had returned TRUE.

This repurposes the existing skip-all test as "combining", since it
is no longer entirely about runs where every test-case was skipped.

If a test is marked with g_test_incomplete(), then it is expected to
fail, so when it fails the test executable should still exit 0
(or possibly 77, if all tests are either skipped or incomplete).

In the test for the unit testing framework, we might as well have
exemplary behaviour. Leave behind a single call to g_assert (TRUE)
just to prove that it still works.

The TAP specification says that failing tests that are currently
expected to fail (like Automake's XFAIL) are to be reported as
"not ok", with that failure ignored as a result of the TODO
directive, with this example:
not ok 3 - infinite loop # TODO halting problem unsolved
A test reported as "ok # TODO" indicates that something that is
expected to fail has unexpectedly succeeded, similar to Automake's
XPASS.

Assigning the gpointer return value from g_atomic_pointer_get() to a

g_test_skip() is appropriate for tests that can't run due to missing
functionality on the host system, whereas g_test_incomplete() is
for expected-to-fail tests for unimplemented functionality in the
code under test.

Testing that an interned string is released once its last reference is
dropped is not possible without a hook into the interning machinery;
just checking that the returned pointer for the same string is going to
be different after the last release() is not guaranteed to work, as the
systema allocator is perfectly within its rights to recycle pointers, as
long as they are unique while valid.

When checking that the timezone code falls back to UTC if a zone is

See previous commit; same reasoning behind the commit, except that these
sources weren’t (yet) causing `make distcheck` to fail.

Instead of messing around with EXTRA_*_SOURCES and manually handling .lo
files, why not just add gwin32.c to the GLib sources conditionally?
This will hopefully fix `make distcheck` failing due to gwin32.Plo not
being generated in the sub-builddir≠srcdir stage, due to depcomp
inexplicably not generating it. (Note that it is correctly generated in
non-distcheck builds.)

The parser state machine for bookmark files did not handle unexpected
nesting of elements, such as a <bookmark> element inside a <title>
element — it would print a critical warning rather than returning a
GError.
Fix that, and add various unit tests for it. The set of tests includes
various other general markup tests as provided by Jussi Judin.
