[cipher.c cipher.h kex.c kex.h kexgexc.c] Add a special case for the DH group size for 3des-cbc, which has an effective strength much lower than the key size. This causes problems with some cryptlib implementations, which don't support group sizes larger than 4k but also don't use the largest group size it does support as specified in the RFC. Based on a patch from Petr Lautrbach at Redhat, reduced by me with input from Markus. ok djm@ markus@
