context: use changelogrevision
Upcoming patches will make the changelogrevision object perform
lazy parsing. Let's switch to it.
Because we're switching from a tuple to an object, everthing that
accesses the internal cached attribute needs to be updated to access
via attributes. A nice side-effect is this makes the code easier to
read!
Surprisingly, this appears to make revsets accessing this data
slightly faster (values are before series, p1, this patch):
