mingw lacks the counterpart to PTHREAD_MUTEX_INITIALIZER, so the best we can do is portably expose once-only runtime initialization. * src/util/threads.h (virOnceControlPtr): New opaque type. (virOnceFunc): New callback type. (virOnce): New prototype. * src/util/threads-pthread.h (virOnceControl): Declare. (VIR_ONCE_CONTROL_INITIALIZER): Define. * src/util/threads-win32.h (virOnceControl) (VIR_ONCE_CONTROL_INITIALIZER): Likewise. * src/util/threads-pthread.c (virOnce): Implement in pthreads. * src/util/threads-win32.c (virOnce): Implement in WIN32. * src/libvirt_private.syms: Export it.
