Now that QemuSemaphore is implemented through pthread_cond_t only, we can use
QemuCond and QemuMutex to make the code smaller. Features such as mutex
tracing and CLOCK_MONOTONIC timedwait are supported in qemu-sem naturally.

Use CLOCK_MONOTONIC, so the timeout isn't affected by changes to
the system time. It depends on the pthread_condattr_setclock(),
while some systems(e.g. mac os) does not support it, so the behavior
won't change in these systems.

POSIX specifies an absolute time for sem_timedwait(), it would be
affected if the system time is changing, but there is not a relative
time or monotonic clock version of sem_timedwait, so we cannot gain
from POSIX semaphore any more.
An alternative way is to use sem_trywait + usleep, maybe we can
remove CONFIG_SEM_TIMEDWAIT in this way? No, because some systems
(e.g. mac os) mark the sem_xxx API as deprecated.
So maybe remove the usage of POSIX semaphore and turn to use the
pthread variant for all systems looks better.

Below is the updated version of the patch adding debugging support to WHPX.
It incorporates feedback from Alex Bennée and Peter Maydell regarding not
changing the emulation logic depending on the gdb connection status.
Instead of checking for an active gdb connection to determine whether QEMU
should intercept the INT1 exceptions, it now checks whether any breakpoints
have been set, or whether gdb has explicitly requested one or more CPUs to
do single-stepping. Having none of these condition present now has the same
effect as not using gdb at all.

The current test checks more than AF_VSOCK availability, and doesn't
need to be that long.
Since its introduction in Linux in 2013, AF_VSOCK came with
linux/vm_sockets.h for sockaddr_vm, let's check that.
We could even go back to the initial configure-less approach
proposed by Stefan Hajnoczi, since Michael Roth added the configure-time
check back then to satisfy glibc in Ubuntu 14. See:

The header has been part of MinGW-w64 since the introduction of the
project (2007). While on MinGW(32), the legacy project, it was imported
in 2014 from w32api-3.17 (commit e4803e0da2).
According to build-platform.rst and our CI coverage, we only support
building with MinGW-w64 (from Debian/Fedora).

Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.
This can help to make some code independent from qemu too.
gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.
