revlog: add 'raw' argument to revision and _addrevision

This patch introduces a new 'raw' argument (defaults to False) to revlog's
revision() and _addrevision() methods.
When the 'raw' argument is set to True, it indicates the revision data should be
handled as raw data by the flagprocessor.

Note: Given revlog.addgroup() calls are restricted to changegroup generation, we
can always set raw to True when calling revlog._addrevision() from
revlog.addgroup().
