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.
