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.
