Bug #198398 - Enable Manifest generation when there are no hash
functions available for types such as RMD160. Now it's possible
to generate a Manifest when python-2.5 is built without ssl
support. MANIFEST1_REQUIRED_HASH and MANIFEST2_REQUIRED_HASH
are the only two functions that are strictly required now (MD5
and SHA1).
