ctype and other sign extension fixes.

with deraadt and millert, ok millert

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

- use strncmp/strncasecmp instead of comparing by character
- simplify istrlcpy, no need to check for isupper
- line[0] is redundant, because strcasecmp will take care of it
ok millert@

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

spelling; from Brian Poole <raj@cerias.purdue.edu>

o ANSIfy
o Style nits
o Use const to silent stupid -Wall warnings
o strnc{py,at} -> strlc{py,at}
o Use strpbrk() instead of homegrown anyof()
o Use NULL instead of #defines with 0 cast to a pointer
This still could use a proper audit

More fixes from Don Beusee:
- edit and other interactive commands have no stdin (making the
command completely broken).
- messages with "From " line having date format with -0800 type of timezone
are not recognized correctly.

NetBSD changes (mostly comsmetic):
replace panic() with calls to err()/errx()
use S_IS* instead of doing by hand with S_IF*.
Use TIMESPEC_TO_TIMEVAL() and gettimeofday instead of time(2)
Use _POSIX_VDISABLE, not 0
Kill register

NOSTR -> NULL
Use sigsetjmp/siglongjmp instead of sigjmp/longjmp for portability.

Merge in NetBSD and 4.4BSD-lite2 changes as well as some of my own.
- handle long lines safely (from NetBSD)
- use puts/fputs and putchar/putc when it makes sense
- use err/errx and warn/warnx when it makes sense
- make return() and sizeof() style consisten
- some more buffer safety

from christos;
- Fix PR/105: Implement dot locking protocol and check return value of flock.
- Fix PR/2247: Don't call unknown users "ubluit". Issue an error message.
- Fix/add prototypes.
- Fix warnings.
- Use POSIX signal mask calls.
