A fix has been committed in upstream glib commit
210a9796f78eb90f76f1bd6a304e9fea05e97617.
(See also related bug https://bugzilla.gnome.org/show_bug.cgi?id=764415)
It is desirable to use the glib version instead of qemu copy, since it
provides more debugging facilities (G_MAIN_POLL_DEBUG etc), and
hopefully has a better maintainance. Hopefully, we can drop the qemu
copy in a few years.

The GSource object has ability to have a name, which is useful
when debugging performance problems with the mainloop event
callbacks that take too long. By associating a name with a
QIOChannel object, we can then set the name on any GSource
associated with the channel.

We're going to make use of g_dir_make_tmp() in test-logging. Provide a
compatibility implementation of it for glib < 2.30.
May behave differently in some edge cases (e.g. pattern only at the
end of the template, the file name is not part of the error message),
but good enough in practice.

include/glib-compat.h defines a bunch of functions based on glib primitives,
and uses assert() without including assert.h. Replace assert() with
g_assert() to make the file more self-contained, and to fix compilation
breakage after 28507a415a9b1e.

Commit 89b516d8b9444ece8ccabb322a9389587c7a7b83 ("glib: add
compatibility interface for g_get_monotonic_time()") aimed
at making qemu build with old glib versions. At least SLES11SP3,
however, contains a backport of g_get_monotonic_time() while
keeping the reported glib version at 2.22.
Let's work around this by a strategically placed #define.

This patch fixes compilation errors when building against glib <2.28.0
due to the missing g_get_monotonic_time() function.
The compilation error in tests/libqos/virtio.c was introduced in commit
70556264a89a268efba1d7e8e341adcdd7881eb4 ("libqos: use microseconds
instead of iterations for virtio timeout").
Add a simple g_get_monotonic_time() implementation to glib-compat.h
based on code from vhost-user-test.c.

Thread API changed in glib-2.31 significantly. Before that version,
conditionals and mutexes were only allocated dynamically, using
_new()/_free() interface. in 2.31 and up, they're allocated statically
as regular variables, and old interface is deprecated.
(Note: glib docs says the new interface is available since version
2.32, but it was actually introduced in version 2.31).
Create the new interface using old primitives, by providing non-opaque
definitions of the base types (GCond and GMutex) using GOnces.
Replace #ifdeffery around GCond and GMutex in trace/simple.c and
coroutine-gthread.c too because it does not work anymore with the new
glib-compat.h.

g_poll has a problem on Windows when using
timeouts < 10ms, in glib/gpoll.c:
/* If not, and we have a significant timeout, poll again with
* timeout then. Note that this will return indication for only
* one event, or only for messages. We ignore timeouts less than
* ten milliseconds as they are mostly pointless on Windows, the
* MsgWaitForMultipleObjectsEx() call will timeout right away
* anyway.
*/
if (retval == 0 && (timeout == INFINITE || timeout >= 10))
retval = poll_rest (poll_msgs, handles, nhandles, fds, nfds, timeout);
so whenever g_poll is called with timeout < 10ms it does
a quick poll instead of wait, this causes significant performance
degradation of QEMU, thus we should use WaitForMultipleObjectsEx
directly
