Very large style makeover.

1) ANSIfy.
2) Clean up ifdefs so that
a) ones that never/always apply are appropriately either
fully removed, or just the #if junk is removed.
b) change #if defined(FOO) for appropiate values of FOO.
(currently AUTHENTICATION and ENCRYPTION)
3) WARNS=2 fixing
4) GC other unused stuff

This code can now be unifdef(1)ed to make non-crypto telnet.

Add __FBSDID() to diff-reduce with "base" telnet.

Forced commit. This is to try and help folks that used the international
crypto repo and have slightly different files but with the same version.
cvsup in 'checkout mode' has no trouble with this, but cvs can get really
silly about it.

Don't call printf with no format string.

This commit was generated by cvs2svn to compensate for changes in r29088,
which included commits to RCS files with non-trunk default branches.

Initial import of BSD telnet. This will be used to build the kerberised
telnet, and after userland diffs have been merged in, will be used to
build the non-kerberised sources as well. (See unifdef(1) for details)
