5941e412ca Add a caching option to dump. Use -C. Note that NetBSD has a caching option 
called -r but it takes 512 byte blocks instead of megabytes, and I felt a
megabytes specification would be far more useful so I did not use the same
option character.

This will *greatly* improve dump performance at the cost of possibly
missing filesystem changes that occur between passes, and does a fairly
good job making up for the loss of buffered block devices.  Caching is disabled
by default to retain historical behavior.

In tests, dump performance improved by about 40% when dumping / or /usr.

Beware that dump forks and the cache may wind up being larger then you
specify, but a more complex shared memory implementation would not produce
results that are all that much better so I kept it simple for now.

194a666749 Add the `L' option to dump to notify it that it is dumping a 
live filesystem. To obtain a consistent dump image, dump takes
a snapshot of the filesystem and then does a dump of the snapshot.
The snapshot is removed when the dump is complete.

Also add an operator warning that the `L' option should be used
if dump is run on a live filesystem without the `L' option being
specified. The alternative would be to silently use a snapshot
any time that a live filesystem is dumped, but this change in
dump semantics seemed too drastic at this time.

7ac806655e dump(8)'s manual page is confusing in its use of records, blocks, 
blocksizes, etc
does not give the default of -b
only mentiones rdump in the NAME section
uses both filesystem and file system in similar contexts

1982ee69fd Implement Kerberized rcmd for rdump/rrestore. This is lacking the 
options one would normally expect to set the realm, enable encryption,
and whatnot, but this actually is able to contact the remote server,
so at least it's a start.  (As a bonus, the stripped static binary is
unquestionably exportable.)
