- Change DH group handling in the pre-generated parts of the
  configuration. Add a -GRP{1,2,5} component to transform and suite
  names to directly specify which group to use. If no group is
  specified, use DH group 2 (MODP_1024). Earlier transforms and suites
  using the MD5 hash defaulted to DH group 1, this is no longer true.
- Unbreak MD5 and SHA1 passphrases in policy check.
- Don't message_dump_raw() bad length messages, i.e too short.
- Fix a couple of snprintf length bugs.
- Compile without warnings for older/newer OpenSSL.
