Implement getcontext(), setcontext(), makecontext(), and swapcontext().
This is a preliminary libc-only implementation. sigprocmask() is used
to mask signals during the context switch and to save and restore signals.
FP registers are not currently saved or restored - that is, synchronous
use is intended.
