changegroup: emit revisiondelta instances from deltagroup()
By abstracting the concept of a delta group away from its
serialization (the changegroup format), we make it easier
to establish alternate serialization formats. We also make
it possible to move aspects of delta group generation into
the storage layer. This will allow storage to make decisions
about e.g. delta parent choices without the changegroup code
needing storage APIs to determine delta parents. We're still
a bit of a way from there. Future commits will work towards
that world.

changegroup: move file chunk emission to generate()
Same deal as manifests. We want to get to a point where we can
emit data structures from deltagroup() and derive the raw
changegroup data as late as possible.

changegroup: move manifest chunk emission to generate()
We want to get to a point where we can emit data structures from
deltagroup() and derive the raw changegroup data as late as possible.

Preparing for all the generate* functions to emit data structures
instead of raw chunks.

changegroup: emit delta group close chunk outside of deltagroup()
I want to make deltagroup() emit data structures rather than
serialized deltas. Upcoming commits will demonstrate why.

changegroup: extract cgpacker.group() to standalone function
It doesn't need to be part of the packer class.

changegroup: pass all state into group()
This will allow us to split it into a standalone function.

changegroup: inline _prune() into call sites
The functionality is pretty simple. As a bonus, _prune() had special
code for the manifest case. We can now exclude this check from the
file call site.

changegroup: inline _packmanifests() into generatemanifests()
It is relatively small. Every other generate*() calls group()
directly. So the new code is consistent.

changegroup: invert conditional and dedent
I don't like seeing code that visually resembles the pyramid of
doom.
