In the kernel: Move the flag UQF_UMTXQ from the thread's td_flags where it was unlocked to the umtx_q struct where it now has locking. Nuke the UMTX_DYNAMIC_SHARED define while here, it's unused and complex. Refactor do_wait so that if we get a signal or timeout AND woken up, we forward the wakeup to any other waiters pending to avoid a missed wakeup. In userland: Bring over some fixes from DragonFlyBSD for the userland part of pthread_condvars, basically relax the consistency on the number of waiters and signals pending because it was both too strict and incorrect causing lost wakeups.

This fixes a NULL-dereference of curthread when libstdc+ initializes the exception handling globals on archs we can't use GNU TLS due to lack of support in binutils 2.15 (i.e. arm and sparc64), yet, thus making threaded C++ programs compiled with GCC 4.2.1 work on these archs.
