On Windows, cpus.c needs access to the hThread. Add a Windows-specific
function to grab it. This requires changing the CPU threads to
joinable. There is no substantial change because the threads run
in an infinite loop.

Rewrite the handshaking between qemu_thread_create and the
win32_start_routine, so that the thread can be joined without races.
Similar handshaking is done now between qemu_thread_exit and
qemu_thread_join.
This also simplifies how QemuThreads are initialized.

Split from Jan's original qemu-thread-posix.c patch. No semantic change,
just introduce the new API that POSIX and Win32 implementations will
conform to.

Makes it easier to catch the bug in gdb as there is no need to set an
explicit breakpoint.

These functions were missing in commit
9257d46d55.
Both functions are needed for compilations with
configuration --enable-vnc-thread.

For now, qemu_cond_timedwait and qemu_mutex_timedlock are left as
POSIX-only functions. They can be removed later, once the patches
that remove their uses are in.
