  Log:
  - Merge struct procsig with struct sigacts.
  - Move struct sigacts out of the u-area and malloc() it using the
    M_SUBPROC malloc bucket.
  - Add a small sigacts_*() API for managing sigacts structures: sigacts_alloc(),
    sigacts_free(), sigacts_copy(), sigacts_share(), and sigacts_shared().
  - Remove the p_sigignore, p_sigacts, and p_sigcatch macros.
  - Add a mutex to struct sigacts that protects all the members of the struct.
  - Add sigacts locking.
  - Remove Giant from nosys(), kill(), killpg(), and kern_sigaction() now
    that sigacts is locked.
  - Several in-kernel functions such as psignal(), tdsignal(), trapsignal(),
    and thread_stopped() are now MP safe.
