Initializes a GMutex so that it can be used.
This function is useful to initialize a mutex that has been
allocated on the stack, or as part of a larger structure.
It is not necessary to initialize a mutex that has been
statically allocated.
To undo the effect of g_mutex_init() when a mutex is no longer
needed, use g_mutex_clear().
Calling g_mutex_init() on an already initialized GMutex leads
to undefined behaviour.
Since 2.32
