changegroup: pass sorted revisions into group() (API)
Currently, group() receives a list of nodes and calls _sortgroup()
to sort them and turn them into revs. Since the sorting behavior
varies depending on the type of data being transferred, I think it
makes sense to perform the sorting before group() is invoked.
This commit extracts _sortgroup() to a pair of standalone functions.
It then moves the calling of these functions to the 3 call sites of
group(). group() now receives an iterable of revs instead of nodes.
