Filipe Manana resolved COUCHDB-1004.

       Resolution: Fixed
    Fix Version/s:     (was: 1.2)

Applied Adam's suggestion (use couch_util:to_existing_atom/1) to 1.0.x and 1.1.x.
Trunk does not suffer from this issue.

> We'd like to additional information to db_info in BigCouch, such as the Q and N constants
for a given database. This causes replication to fail when replicating from BigCouch to CouchDB
due to the use of list_to_existing_atom in couch_rep:dbinfo(...
> The claim is that list_to_atom pollutes the atoms table, however superficial testing
indicates this is not the case, list_to_atom when called repeatedly seems to work fine. If
this is true then consider reverting list_to_existing_atom back to list_to_atom.
