hgweb: log headers only if headers were successfully parsed
The headers attribute is not initialized in certain error situations
(e.g. http 400 bad request). Check for self.headers before we attempt
to access it.
Check whether size of generaldelta revlog is not bigger than its
regular equivalent. Test would fail if generaldelta was naive
implementation of parentdelta: third manifest revision would be fully
inserted due to big distance from its paren revision (zero).
