Andrew Gallatin f16647740e Simplify and correct OSF/1 signal handling.
- No signal translation is needed.  Our signals match the OSF/1 signals
- an OSF/1 sigset_t is 64 bits.  Make certain to use all 64-bits of it.
  We'd previously only used the lower 32 bits.   This was mostly harmless
  as I don't know of an OSF/1 apps which use any signals > 31.  However,
  the alpha Linux ABI uses the osf/1 signal routines and threaded linux
  apps tyically use signals 32 and 33 to comminicate with the manager
  thread, so it is important we preserve the upper 32-bits.
