Remove unused headers and sort the remaining
Remove lint-style comments
Swap hardcoded string on usage() for __progname

OK tb@

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution. These are the files confirmed
through binary verification.
ok guenther, millert, doug (helped with the verification protocol)

some inconsequential cleanups. ok deraadt

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

synchronize usage and synopsis.

Plug a mem leak. Found in one of my trees. Forgat where it came from; most
likely from a NetBSD Coverity fix. ok ray@

kill more registers

millert@ ok

exit(-#) is wrong

Redress PR 1547. Provide an option to pass high characters without
escaping, and turn it off by default. Checked by angelos@.

Some changes inspired by FreeBSD...
o Kill annoying spaces at the end of lines
o sigaction, not sigvec
o warn/err where sensible
o hstrerror() not herror()
o defaults for erase, kill, and werase if not set
o kill a needless refresh() after the beeps that was messing up the screen

NetBSD-based -Wall cleanup

Catches luser/typo when "@" is the first character of first argument
