Tim J. Robbins a95edcba94 Fix a multitude of security bugs in the iBCS2 emulator:
- Return NULL instead of returning memory outside of the stackgap
  in stackgap_alloc() (FreeBSD-SA-00:42.linux)
- Check for stackgap_alloc() returning NULL in ibcs2_emul_find();
  other calls to stackgap_alloc() have not been changed since they
  are small fixed-size allocations.
- Replace use of strcpy() with strlcpy() in exec_coff_imgact()
  to avoid buffer overflow
- Use strlcat() instead of strcat() to avoid a one byte buffer
  overflow in ibcs2_setipdomainname()
- Use copyinstr() instead of copyin() in ibcs2_setipdomainname()
  to ensure that the string is null-terminated
- Avoid integer overflow in ibcs2_setgroups() and ibcs2_setgroups()
  by checking that gidsetsize argument is non-negative and
  no larger than NGROUPS_MAX.
- Range-check signal numbers in ibcs2_wait(), ibcs2_sigaction(),
  ibcs2_sigsys() and ibcs2_kill() to avoid accessing array past
  the end (or before the start)
