Make this header a little bit more XSI-compliant:

Browse Source 
- Define type rlim_t and struct timeval.  This makes autoconf
  happier.  (PR: 62388)
- Add RLIMIT_AS, which is an alias for our RLIMIT_VMEM.
- structs orlimit and loadavg, as well as macros CP*, should
  only appear if __BSD_VISIBLE.
- Use underscored versions of int32_t and fixpt_t in case
  <sys/types.h> is not included.
- Document areas of non-conformance.
