John Baldwin 2ad7d3049a - Change CURSIG() and postsig() to require that the proc lock is held ...

rather than grabbing it and releasing it themselves.  This allows callers
  of these functions to get the lock to close race conditions.
- Grab Giant around ktrace in postsig.
- Count the switches performed on SIGSTOP's as involuntary context switches
  in the resource usage stats.
