bundle: move writebundle() from changegroup.py to bundle2.py (API)
writebundle() writes a bundle2 bundle or a plain changegroup1. Imagine
away the "2" in "bundle2.py" for a moment and this change should makes
sense. The bundle wraps the changegroup, so it makes sense that it
knows about it. Another sign that this is correct is that the delayed
import of bundle2 in changegroup goes away.
I'll leave it for another time to remove the "2" in "bundle2.py"
(alternatively, extract a new bundle.py from it).
