sommerfeld 4b5ec636eb Fix obvious LP64 and aliasing bogons in checksum verification code.
Should fix spurious "bad checksum" errors on alpha, but not yet tested
on that platform.

fvdl 9ba6417ed1 Don't try to print an NFS packet over TCP when there's not enough space
for an RPC header (--> garbage && coredumps).

fvdl d65ddbd4e0 Grok NFSv3 packets. Needs a bit of work but is ok for now. Enable dumping
of NFS packets over TCP. Upgrade to 3.0.4 while at it. 3.0.4 fixes previous
fix made to util.c too; 'official' fix applied instead (very minor difference).

Fixes to be sent to maintainers RSN.
