Tries to lock mutex. If mutex is already locked by another thread,
it immediately returns FALSE. Otherwise it locks mutex and returns
TRUE.
Note
GMutex is neither guaranteed to be recursive nor to be
non-recursive. As such, calling g_mutex_lock() on a GMutex that has
already been locked by the same thread results in undefined behaviour
(including but not limited to deadlocks or arbitrary return values).
