Update some stuff related to the syscalls change:
- restart syscalls which return ERESETARTSYS
- make code to restart a syscall common
- keep a process-wide pending signal set to store as-yet
undelivered signals (only used in 2.4 mode; TODO: siginfo, queues)
- make execve work a bit better - it is impossible to recover from
execve failing, so we try to check that it will before running the
syscall itself (also fixes bug with SuSE 8.2 kernel)
