revlog: test possible read race condition with splitting

This is currently working fine, but could break with another approach (for
example, with the one we are about to use in the next changesets…)

So we make sure the case is covered.

  $ echo bar > bar

Pull a missing revision:

  $ hg pull -qr missing ../repo
  abort: unknown revision 'missing'
  [10]

Pull multiple revisions with update:

  $ hg pull -qu -r 0 -r 1 ../repo
  $ hg -q parents
  0:bbd179dfa0a7
  $ hg rollback
  repository tip rolled back to revision -1 (undo pull)
  working directory now based on revision -1

  $ hg pull -qr 0 ../repo
  $ hg log

This used to abort: received changelog group is empty:

  $ hg pull -qr 1 ../repo

Test race condition with -r and -U (issue4707)

We pull '-U -r <name>' and the name change right after/during the changegroup emission.
We use http because http is better is our racy-est option.
