Subject: c threads, v.5.9

this is now a version that I am quite confident of. It is a special
edition that doesn't use spinlocks. The only "principal" thing it
still has that people might not like is dynamic allocation of
auxiliary structures for mtx_t and cnd_t. For the mtx_t, this could
perhaps be avoided, but for the cnd_t it is really convenient, because
it clearly separates different batches of cnd-waiters that should
never be mixed.

In summary:

 - (almost) all is private futex
 - the internal locks use a minimal test-and-set logic that is modeled
   after C's atomic_flag
 - mutexes and conditions are simpler (I hope) than their pthread
   counterparts because they don't need process sharing or robustness
