If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
Expand the set of available probes, and add a few more output parameters
to some of the existing ones to make them more useful. I do not know if
this breaks any existing stability guarantees for GLib’s SystemTap
tapset, as it is effectively just adding some more local variables in
the user’s probe.

Add various (nullable) and (optional) annotations which were missing
from a variety of functions. Also port a couple of existing (allow-none)
annotations in the same files to use (nullable) and (optional) as
appropriate instead.
Secondly, add various (not nullable) annotations as needed by the new
default in gobject-introspection of marking gpointers as (nullable). See
https://bugzilla.gnome.org/show_bug.cgi?id=729660.
This includes adding some stub documentation comments for the
assertion macro error functions, which weren’t previously documented.
The new comments are purely to allow for annotations, and hence are
marked as (skip) to prevent the symbols appearing in the GIR file.

It’s unfortunately common to see worker threads being spawned all over
the place to do operations which could be brought into the main thread
with an async call, simplifying everything.

Since we are no longer using sgml mode, using /* */ to
escape block comments inside examples does not work anymore.
Switch to using line comments with //
In Windows development environments that have it, <unistd.h> is mostly
just a wrapper around several other native headers (in particular,
<io.h>, which contains read(), close(), etc, and <process.h>, which
contains getpid()). But given that some Windows dev environments don't
have <unistd.h>, everything that uses those functions on Windows
already needed to include the correct Windows header as well, and so
there is never any point to including <unistd.h> on Windows.
Also, remove some <unistd.h> includes (and a few others) that were
unnecessary even on unix.

Switch GCond to using monotonic time for timed waits by introducing a
new API based on monotonic time in a gint64: g_cond_wait_until().
Deprecate the old API based on wallclock time in a GTimeVal.
Fix up the gtk-doc for GCond while we're at it: update the examples to
use static-allocated GCond and GMutex and clarify some things a bit.
Also explain the rationale behind using an absolute time instead of a
relative time.
We'll hold out on this until someone has a really convincing reason for
why they need to control the stack size.
If we do decide to add it back, it should probably have a name like
_new_with_stack_size(), not _full().
And remove the 'joinable' argument from g_thread_new() and
g_thread_new_full().
Change the wording in the docs. Clarify expectations for
(deprecated) g_thread_create().
GThread is freed using some very slightly confusing logic: if the thread
was created 'joinable', then the structure is freed after the join()
call succeeds (since we know the thread has exited). If the thread was
not created 'joinable' then the free is when the thread quits (since we
know 'join' will not be called later).
Move to a straight ref-counting system: 1 ref owned by the thread and 1
extra ref if the thread is joinable. Both thread quit and joining will
decrease the refcount by 1.
Keep track of if we created a thread for ourselves or if the GThread*
was allocated in response to g_thread_self() on a previously-unknown
thread.
Only call g_system_thread_free() in the first case.
Add g_system_thread_new() and g_system_thread_free(), implemented with
GSlice. Use those instead of g_new() and g_free().
Presently, the backends are both doing the same thing. This will change
soon.
