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

Revert most part of 200420 as requested, as more review and polish is
needed.

Remove unneeded header includes from usr.bin/ except contributed code.

Tested with: make universe

Add support for multibyte characters. The output is questionable when a
character straddles the "start" or "stop" columns, but this should be
quite uncommon.

ANSIify function definitions to avoid a warning.

remove __P

Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

Style stuff.
Sort includes.
Remove 'register'
Use __FBSDID().

$Id$ -> $FreeBSD$

Tweaks to allow compiling -Wall (mostly adding "const" to char rcsid[]).

-Wall cleanup.

Remove lines inside #ifdef 0/#endif.

Use err(3) instead of local redefinition.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.
