r269806:
Fix too long (seed length >12 chars) challenge handling.
1) " ext" length should be included into OPIE_CHALLENGE_MAX (as all places
of opie code expects that).
2) Overflow check in challenge.c is off by 1 even with corrected
OPIE_CHALLENGE_MAX
3) When fallback to randomchallenge() happens and rval is 0 (i.e.
challenge is too long), its value should be set to error state too.

To demonstrate the bug, run opiepasswd with valid seed:
opiepasswd -s 1234567890123456
and notice that it falls back to randomchallenge() (i.e. no
1234567890123456 in the prompt).

r269809:
When sha1 support was added, they forget to increase OPIE_HASHNAME_MAX

r269811:
Last '/' for program name, not first one.

r269810:
Link otp-sha1 to match real challenge prompt, not otp-sha.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Add opie lib dir to includes list

Remove the WANT_INSECURE_OPIE option - it is now a default. This is not
nearly as ominous as it sounds, and it allows OPIE to be used over SSH
and on xterms.

Requested by: ache
Discussed on: -security

Switch on SHA1 hashing.

Provide a WANT_INSECURE_OPIE compile-time option, which is useful if
you encrypt all traffic routinely, and is also useful for debugging.

Also, (properly) set SUID bit on relevant apps - opieinfo and
opiepasswd, which need it to mess with /etc/opiekeys.

MAN[1-9] -> MAN.

Fix minor style nits.

Install otp-md{4,5} bits.
