rHG3634ed953a42: changegroup: clean up changelog callback
Summary

changelog.read() calls changelog.changelogrevion() then turns it into
a tuple. Let's call changelogrevision() directly and used named
attributes to make code easier to read.

While we're here, also change some variable names to make code easier
to read.
