Changes from APPLIANCE_HEAD:

    source/smbd/server.c
    source/nmbd/nmbd.c
        - Fixed a very subtle bug with signals. Seems that POSIX requires
          that the signal mask be inhereted. So, if you happen to kick off
          smbd/nmbd from code that has the mask set on SIGUSR1, you lose
          messages.
(This used to be commit b4c98196fc65e8b3bce928296e854987622eae78)
