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.
We now cache the revlog data ~4MB at a time.
The memory used server side when pulling goes down to 35Mo maximum
whereas without the patch more than 160Mo was used when cloning the linux kernel
repository.
The time used by cloning is higher mainly because of the check in revlog.revision.
