  sigset_t change (part 4 of 5)
  -----------------------------
  
  The compatibility code and/or emulators have been updated:
  
  iBCS2 now mostly uses the older syscalls. SVR4 now properly
  handles all signals. This has been achieved by using the
  new sigset_t throughout the emulator. The Linuxulator has
  been severely updated. Internally the new Linux sigset_t is
  made the default. These are then mapped to and from the
  new FreeBSD sigset_t.
  
  Also, rt_sigsuspend has been implemented in the Linuxulator.
  Implementing this syscall basicly caused all this sigset_t
  changing in the first place and the syscall has been used
  throughout the change as a means for testing. It basicly is
  too much work to undo the implementation so that it can
  later be added again.
  
  A special note on the use of sv_sigtbl and sv_sigsize in
  struct sysentvec:
  Every signal larger than sv_sigsize is not translated and is
  passed on to the signal handler unmodified. Signals in the
  range 1 upto and including sv_sigsize are translated.
  The rationale is that only the system defined signals need to
  be translated.
  
  The emulators also have been updated so that the translation
  tables are only indexed for valid (system defined) signals.
  This change also fixes the translation bug already in the
  SVR4 emulator.
