cleanup of revlog.group when repository is local
revlog.group cached every chunk from the revlog, the behaviour was
needed to minimize the roundtrip with old-http.
The patch export the information that the repository is local or not
from the repository object down to the revlog.
Then it uses the workaround for old-http only if the repository is non-local.
The memory used server side when pulling goes down to less than 30Mo maximum
whereas without the patch more than 160Mo was used when cloning the linux kernel
repository.
The time used by cloning is roughly the same (although some caching could be
implemented if needed):
