svn commit: r313734 - head/sys/sys

Log:
  Add RLIM_SAVED_MAX and RLIM_SAVED_CUR symbols.
  
  Define them as RLIM_INFINITY.  This is allowed by POSIX in case all
  resource limits are representable in an object of type rlim_t.  Since
  we do not allow negative rlim_t, with some strength this definition is
  conforming.
  
  We are not conforming fully still because POSIX requires rlim_t to be
  unsigned type.  Fixing this without breaking ABI to redefine
  RLIM_INFINITY is impossible.
