Release 4.6: DB_MPOOLFILE->put

The DB_MPOOLFILE->put method takes a new parameter in the Berkeley DB 4.6 release, a page priority. This parameter allows applications to specify the page's priority when returning the page to the cache.

Applications calling the DB_MPOOLFILE->put method can upgrade by adding a DB_PRIORITY_UNCHANGED parameter to their calls to the DB_MPOOLFILE->put method. This will result in no change in the application's behavior.
