  these fixes are accomplished by calling sigreturn(uctx) to restore the
  state instead of trying to roll our own in userland.  This won't be much
  slower (if at all) because we had to save and restore the signal state
  in the userland code anyway, so we could not avoid making at least one
  system call.

  Using sigreturn() handles the signal mask atomicy for us so we don't have
  to deal with it and fixes numerous other issues.  Along with this change,
  adjust getcontext() and makecontext() to fill out additional important
  fields in the ucontext that sigreturn() inspects.

* Fixes two stack corruption bugs. First, getcontext() was calling
  get_mcontext() and get_mcontext() was setting up the setcontext return
  state to return 1 ... from get_mcontext(), NOT from getcontext().  If
  normal operations or signals mess with the stack, the double return
  will not work.  Oops.

  Secondly, getcontext scribbled over the red-zone in a way that is not

* setcontext() was restoring the context as saved by makecontext() or
  getcontext(), but setcontext() can also be called with the ucontext
  from the signal handler which requires a full restore.  setcontext()
  was not restoring FPU or scratch registers or rflags.

* Fixes signal restoration bug and corruption that can mess up emulation
  in qemu.
