Previously, in the case where 'kf' has more than one ref, calling
g_key_file_free(kf) would break it. For example, calling
g_key_file_has_key(kf, ...) would hit the following assertion:
g_hash_table_lookup: assertion 'hash_table != NULL' failed
This is because g_key_file_free() calls g_key_file_clear() which sets
self->groups and other fields to NULL; most lookup functions assume
these fields are non-NULL.
One fix would be to call g_key_file_init() right after
g_key_file_clear() in g_key_file_free(). However, in the case where
there are no other refs to the keyfile, this would mean allocating
many new hash tables which will be immediately destroyed when
g_key_file_unref() removes the last ref. Instead, inline the unref, and
re-initialize the internal state when the keyfile is still alive.
1) Creating a directory with 0666 does not prevent
traversal on Windows (ACL determines the possibility
of traversal, and Windows mkdir() does not translate
permission bits into ACL). Don't do the traversal check on Windows.
2) Creating a file with 0555 also isn't translated into
read-only ACL, Windows sets the read-only attribute instead,
which blocks all changes, including changes to file times.
Add the write permissions on Windows before changing file times.
On 32 bit systems, the size of a long might be the same as the size of
an int. In that case, we won't be able to get an overflow when
converting from a GTimeVal to a time_t. Skip the test for this in that
case.

Test a few situations where NULL values for optional out parameters
weren’t being tested. This takes the branch coverage of GHashTable up to
100% (ignoring g_return_if_fail() branches).

The new typeof() macro version of g_clear_pointer() was evaluating its
pointer argument more than once, meaning any side effects would be
evaluated multiple times.
The existing (other) macro version of g_clear_pointer() was evaluating
its argument exactly once. This mismatch could have confused people or
lead to subtle bugs.

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.

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.

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.

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.

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.

When formatting the error messages for markup parsing errors, the parser
was unconditionally reading a UTF-8 character from the input buffer —
but the buffer might end with a partial code sequence, resulting in
reading off the end of the buffer by up to three bytes.
