Cornelia Huck 14655e9a18 glib-compat: fix problems with not-quite glib 2.22
Commit 89b516d8b9 ("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.

Stefan Hajnoczi 89b516d8b9 glib: add compatibility interface for g_get_monotonic_time()
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
70556264a8 ("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.

Michael Tokarev 86946a2d83 glib-compat.h: add new thread API emulation on top of pre-2.31 API
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.

Sangho Park 5a007547df glib: fix g_poll early timeout on windows
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

Stefan Hajnoczi f95c967a79 glib: move g_poll() replacement into glib-compat.h
We have a dedicated header file for wrappers to smooth over glib version
differences.  Move the g_poll() definition into glib-compat.h for
consistency.
