John Baldwin e43257aa7d Finish fixing up Alpha to work with an MP safe ptrace():
- ptrace_single_step() is no longer called with the proc lock held, so
  don't try to unlock it and then relock it.
- Push Giant down into proc_rwmem() instead of forcing all the consumers
  (including Alpha breakpoint support) to explicitly wrap calls to
  proc_rwmem() with Giant.
