Major fixup/cleanup of rpcd for nfs.

Fixes for ypbind.

Please eliminate space before "udp" in inetd_child calls.  This will not 
work correctly with the space.

Added reserved_port_type attribute for all ports less than 1024.  NIS is 
causing problems generating avc messages
on these ports for random name_bind.  Want to be able to tell system to 
don't audit these.   Might want to add a boolean
to specifiy whether using NIS or not.

misc fixes.
