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

make wall(1) work with pts.

Change iov_base's type from `char *' to the standard `void *'. All
uses of iov_base which assume its type is `char *' (in order to do
pointer arithmetic) have been updated to cast iov_base to `char *'.

WARNS=2 fix, use __FBSDID().

Not added to Makefile as WARNS=2 will be made default.

- Move the prototype of ttymsg() into ttymsg.h. syslogd and talkd
also use this, and they shouldn't have to have their own prototypes.

- Silence warnings about constness and signedness in ttymsg(). This
includes changing the return value to a `const char *', and changing
the types of `left' and `wret' (both byte counts) to ssize_t.

Forced commit: F_SETFL is used to clear O_NONBLOCK, not F_SETFD.
The code was right, the comment in the PR was wrong.

O_NONBLOCK was used as a command with a bogus arg to fcntl(2).
Change it to F_SETFD with an arg of 0 to clear O_NONBLOCK.
