  Log:
  Implement _ia64_save_context() and _ia64_restore_context(). Both
  functions are derived from the swapctx() and restorectx() (resp)
  from sys/ia64/ia64/context.s. The code is expected to be 99%
  correct, but has not yet been tested.
  
  Note that with these functions operating on mcontext_t, we also
  created the foundation upon which we can implement getcontext(2)
  and setcontext(2) replacements. It's not guaranteed that the use
  of these syscalls and _ia64_{save|restore}_context() on the same
  uicontext_t is actually going to work. Replacing the syscalls is
  now trivially achieved.
  
  This commit completes the ia64 port of libpthread itself (modulo
  testing and bugfixes).
