Support for replication over SSL. Resolves COUCHDB-491

This turned out to be a decent amount of work, since:

1) ibrowse did not use SSL on dedicated connections.  Wrote a simplistic patch,
   will contact Chandru for further discussion.
2) When nginx is used for the SSL wrapper, it wants to buffer the changes feed.
   Setting "proxy_buffering off" in nginx.conf helps, but some buffering still
   occurred. Fixed by making couch_rep_changes_feed smart enough to split
   merged chunks.
3) The Erlang ssl application showed instabilities when used with {active,once}.
   Switched to the "new implementation" using {ssl_imp, new} and instabilities
   disappeared.
