* main.h, seskey.c (encode_md_value): Modify to allow a q size greater

Browse source 
than 160 bits as per DSA2.  This will allow us to verify and issue DSA2
signatures for some backwards compatibility once we start generating DSA2
keys.
* sign.c (do_sign), sig-check.c (do_check): Change all callers.

* sign.c (do_sign): Enforce the 160-bit check for new signatures here
since encode_md_value can handle non-160-bit digests now. This will need
to come out once the standard for DSA2 is firmed up.
