Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

Discussed with: imp, rwatson

Remove done() which was just exit() so use of warn()/err() can be made. Abort
on allocation failure instead of displaying a warning and deferencing NULL
pointer after. Spelling. Add prototypes. Add list of option in synopsis section
of man page, -d is not referenced because available as a compile option. It
should be made a runtime option btw.

Consistently use FBSDID

Fix preprocessor directive syntax (text after #endif).
The style of this program is still atrocious (not fixed).

Remove trailing whitespace.
