disable decryption for foreign sites

4.4BSD snapshot (revision 8.1); add 1993 to copyright

disable decryption for foreign sites

fix typo (wonder how this was tested???); KNF for return ()

check that chars are 8 bits; change the way that long pw's are
encrypted; minor cleanups -- from Tom Truscott

add return values to setkey, encrypt, des_setkey, des_cipher to
distinguish failure (no hardware support or foreign distribution)

new copyright; att/bsd/shared

#define '_' in pwd.h as _PASSWORD_EFMT1

change null characters in salt or iteration to be '.', avoiding bug
where crypt("anything!", "*") returned "*"; lots of comment changes, minor
cleanups

Tom Truscott's version of crypt

Add include files to get prototype declarations, and fix bugs found.
