changegroup: move revision maps to cgpacker
And remove the underscores so the variables conform to our
naming convention.
The logic in _close() should be the only thing warranting scrutiny
during review.

changegroup: move changelogdone into cgpacker
Looking at what it is used for, it feels like there is a better
way to implement all this. So recording a TODO to track that.

changegroup: declare shallow flag in constructor
Thus begins the process of better formalizing ellipses and shallow
changegroup generation mode so it is tracked by cgpacker at
construction time instead of bolted on after the fact by a
wrapper function.

changegroup: make some packer attributes private
These methods and attributes are low level and should not be
called or outside outside of instances. Indicate as such through
naming.

changegroup: rename cg1packer to cgpacker
There is now only a single class. We don't need to encode the
version in its name since the version is a lie.

changegroup: control delta parent behavior via constructor
The last remaining override on cg2packer related to parent delta
computation. We pass a parameter to the constructor to control
whether to delta against the previous revision and we inline all
parent delta logic into a single function.
With this change, cg2packer is empty, so it has been deleted.

changegroup: control reordering via constructor argument
cg2packer.__init__ exists just to override self._reorder. Let's
parameterize this behavior via an argument to the parent's
__init__.
The logic for self._reorder is kinda wonky. None is used as a
special value and the value should be None in some situations.
It is probably worth rewriting this logic to make behavior more
explicit. This will likely happen as part of future work to
control the delta generation process that I have planned.

changegroup: consolidate tree manifests sending into cg1packer
Previously, we overrode a method to control how manifests were
serialized. This method was redefined on cg3packer to send tree
manifests.
This commit moves the tree manifests sending variation to cg1packer
and teaches the cgpacker constructor to control which version to
use.
After these changes, cg3packer was empty. So it has been removed.

changegroup: pass end of manifests marker into constructor
cg3 inserts a custom marker in the stream once all manifests
have been transferred. This is currently abstracted out by
overriding a method.
Let's pass the end of manifests marker in as an argument to avoid
the extra method.
