rHG2943141f5e07: revset: pass repo when passing ui
rHG2858f7d10344: revset: pass repo when passing ui
Summary

The repo instance is currently only used to provide a changeset
lookup function as part of parsing revsets. I /think/ this allows
node fragments to resolve. I'm not sure why we wouldn't want this
to always "just work" if parsing a revset string.

Plus, an upcoming commit will introduce a new consumer that needs a
handle on the repo. So passing it more often will make that code
work more.

Passing a repo instance in all callers of revset.match* results in
a bunch of test changes. Notably, branch and tags caches get
populated as part of evaluating revsets. I'm not sure if this is
desirable. So this patch takes the conservative approach and only
passes the repo if we're passing a ui instance.

Taking this one, but going to punt on D98 per the "consider this an RFC" comment I saw.

Perhaps these two shouldn't pass ui nor repo. They evaluate
internal query.

Passing repo means to take any valid old-style revisions
ignoring the revset syntax.
