Set the soft openfiles limit to maxfiles instead of to NOFILE.

Browse Source 
The limit is now only used by init, so it may as well be "infinite".
Don't use RLIM_INFINITY, since setrlimit() doesn't allow setting
that value.  Use maxfiles instead of RLIM_INFINITY for the hard
limit for the same reason.

Similarly for the maxprocesses limits (use the "infinite" value of
maxproc instead if MAXUPRC and RLIM_INFINITY).

NOFILES, MAXUPRC, CHILD_MAX and OPEN_MAX are no longer used in
/usr/src and should go away.  Their values are almost guaranteed to
be wrong now that login.conf exists, so anything that uses the values
is broken.  Unfortunately, there are probably a lot of ports that
depend on them being defined.

The global limits maxfilesperproc and maxprocperuid should go away
too.
