changegroup: inline _revchunk() into group()
_revchunk() was pretty minimal. I think having all the code for
generating data composing the changegroup in one function makes
things easier to understand.
As part of the refactor, we now call the _revisiondelta* functions
explicitly. This paves the road to refactor their argument
signatures.
