POSIX Threads/Semaphores implementation

[vmlemon]

In order to implement POSIX compatibility, for #7, to port things like SQLite, MojoELF, nedmalloc, and V2Lin, we need to implement pthreads, and semaphores, it seems.

For instance, the unbuildable surface required by V2Lin looks like:

We now have at least the FreeBSD implementation of mcontext_t, which at least gets MegaHAL further, but I haven't retested v2lin_v02, yet.

Seems to get MegaHAL to the following stage:
