Replace Sun RPC license with a 3-clause BSD license. This license change
was approved in 2010 by Wim Coekaerts, Senior Vice President, Linux and
Virtualization at Oracle Corporation.

Use __FBSDID vs. rcsid[].

remove unneeded sys/ucred.h include

$Id$ -> $FreeBSD$

Make rcsid a const char[] instead of char[] to avoid compiler warnings

Changes to support version 3 of the NFS protocol.
The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server. It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.

Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs. Servers will need to build and
install /usr/sbin/mountd.

NFS diskless support is untested.

The bootparam protocol file needs some extra includes in FreeBSD in order
to properly resolve some definitions in <nfs/nfs.h>. I suppose nobody noticed
this before because no one's tried to build bootparamd in FreeBSD until
now.

(Yes, you read that right: I've got bootparamd ready to go. And
rarpd is on the way. :)

Moved 1.1.5 RPC service files from 1.1.5. Tese are the correct ones;
the ones in /usr/src/lib/librpc/rpcsvc are somewhat bogus and will
be deleted.
