The threads used to iterate at least 10000 times before setting the
"seen thread" flag to true. After porting they inadvertently did that
in the first iteration.
Previously, the test assumed that thread1 and thread2 would be scheduled
enough to set seen_thread{1,2} by the fact that the test runs for a high
number of iterations. On some platforms/schedulers, that’s not true,
which causes the test to spuriously fail.
Fix that by forcing the test to continue iterating until both threads
are seen. If this takes too long, the Meson test runner timeout will be
hit and the test will be terminated.

Previously, all three threads would access several global variables
without locking.
Fix that by using atomic accesses to data stored within the
test_closure_refcount() function, which also eliminates the global state
(which would confuse further tests if they were added to this file).

g_assert() can be compiled out if G_DISABLE_ASSERT is defined; and
g_assert_*() provide more specific error messages on failure.

These functions are not run more than once, so the variables don’t need
to be static to save state between runs.

At that point in the code, len can only be 0, 1 or 2. The code below is
a no-op if (len == 0), so the condition is pointless.
Remove it, and we should be able to achieve full branch coverage of
gbase64.c.
This should introduce no functional changes.

While I’m here, we might as well check that we output what the RFC says
we should output.

Relax a precondition in g_base64_encode_step() to allow this. It’s valid
to base64 encode an empty string, as per RFC 4648.
Similarly for g_base64_decode(), although calling it with a NULL string
has never been allowed. Instead, clarify the case of calling it with an
empty string.
This includes a unit test.

The caller needs to check this themselves in any case, so we might as
well at least follow convention in defining the precondition.

Previously pattern_coalesce incorrectly concluded that maybe type is not
present when one pattern starts with `M` and other pattern with anything
else than `M` or `m`. This is false when the other pattern is `*`, since
it includes the maybe type.
Commit 084e1d868 added a preallocation to an array to avoid
reallocations later on, but neglected the fact that after N insertions
into the array, there’s always a NULL terminator added to the end. Fix
the preallocation to include that NULL terminator.
This doesn’t change the correctness of the code, but should eliminate
one reallocation.

There are some cases where valgrind turns up leaks that are already
suppressed in the file, but with a slight difference at the top of the
stack. Add suppressions for these cases as well.
Synchronize access to cancelled flag of cancellable, which was
previously access without synchronization in g_cancellable_is_cancelled.
Use atomic operations instead of existing global mutex, to avoid
serializing calls to g_cancellable_is_cancelled across all threads.
Ensure that source is attached to the context before it migth be used
from another thread, since otherwise operation on source are
unsynchronized and not thread-safe.
In particular there was a data race between g_source_attach and
g_source_set_ready_time (used from g_file_monitor_source_handle_event).
GValue g_type field is used for synchronization with g_once_init_enter,
and so it should be written to only with g_once_init_leave.
Replace structure copy with memcpy that copies the one remaining field
of GValue, i.e., data array.
