Add a library to catch calls to pthread_mutex* and *specific* functions

where the base system doesn't provide stubs for non-threaded programs
(which is just NetBSD<=2 for now).
This is absolutely primitive and just sufficient to make MesaLib usable
with nonthreaded programs.

+Provide dummy implementations of pthread functions like mutex operations
+to enable libraries to be used in both thread-aware and non-threaded programs.
+This is for NetBSD<=2; newer operating systems don't need it.
