Previously, there were two copies of telnet; a non-crypto version
that lived in the usual places, and a crypto version that lived in
crypto/telnet/. The latter was built in a broken manner somewhat akin
to other "contribified" sources. This meant that there were 4 telnets
competing with each other at build time - KerberosIV, Kerberos5,
plain-old-secure and base. KerberosIV is no longer in the running, but
the other three took it in turns to jump all over each other during a
"make buildworld".
As the crypto issue has been clarified, and crypto _calls_ are not
a problem, crypto/telnet has been repo-copied to contrib/telnet,
and with this commit, all telnets are now "contribified". The contrib
path was chosen to not destroy history in the repository, and differs
from other contrib/ entries in that it may be worked on as "normal"
BSD code. There is no dangerous crypto in these sources, only a
very weak system less strong than enigma(1).
Kerberos5 telnet and Secure telnet are now selected by using the usual
macros in /etc/make.conf, and the build process is unsurprising and
less treacherous.
