Remove last remains of FSMID support from userland.

The kernel side was added in 2005 (7d15906a7a159575b1983f7c1fadde4b)
and removed again in 2009 (d98152a8b8a4b368ca0e08b84302f2f2).

cpdup - roll 1.18 for ports consumers

* Add the -n option. This is the not-for-real option. cpdup will go through
the motions but not actually take any action. Useful for validating a
topology without modifying it, e.g. 'cpdup -n -v -VV source target'.

* Fix clang static/global and alignment warnings

* Bump rev to 1.18

* Porters please note that this release has added an __aligned(n)
directive to two structures. BSDs and linux's should be able to
handle this no-problem but just like __printflike() it is a bit
of a departure from standard.

Add parallel transaction support for remote source or target specifications.
The implementation is a bit crude because I don't want to take too many
chances on a codebase that wasn't originally designed to be multi-threaded,
so the master mutex is only released when a thread is waiting for input
on a socket.

* Add the -p<threads> option and compile -pthread by default. This is only
useful when the source and/or destination is a remote host. Note that
parallel transaction mode will not work with older cpdup binaries on the
remote end.

This greatly improves cpdup's performance when operating on a remote
source and/or target.

* Add -l to force stdout and stderr to be line-buffered.

Add a remote host capability for both the source and target directory
specifications. A specification in the form user@host:path will initiate
a ssh link to the remote machine and attempt to run a cpdup slave.

The protocol is not all that fast but it is a good start. The cpignore
and md5 features are not currently available for remote sources and the
fsmid feature is not currently available for remote targets. However, the
incremental backup feature (-H) *IS* available.

The code is currently considered to be highly experimental and does
not yet adjust for mismatched byte orderings (but the protocol is designed
to make this possible in the future).

Add -k/-K to have cpdup use the experimental FSMID to detect changes,

It should be noted that using cpdup with a NFS or other remote filesystem
as the source with this option will not work, since the NFS client cannot
currently detect if the server (or some other client) has modified a file
or directory.
