run-tests: attempt to fix iolock handling

Ideally, when using -j and -i together, when a prompt comes up, we'd
like all other output to wait (but testing to continue!). This gets
other output to wait by adding back a bunch of the locking that
formerly existed. We switch to a recursive lock to deal with the
restructuring due to unittest compatibility.

Running tests continue to run, but now the scheduler doesn't schedule
any new tasks while waiting at a prompt because no task slots become
available due to result output happening in the thread and
blocking on the iolock.

Test issue2761

  $ hg init

  $ touch to-be-deleted
  $ hg add
  adding to-be-deleted
  $ hg ci -m first
  $ echo a > to-be-deleted
  $ hg ci -m second
  $ rm to-be-deleted
  $ hg diff -r 0

Same issue, different code path

  $ hg up -C
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ touch does-not-exist-in-1
  $ hg add
  adding does-not-exist-in-1
  $ hg ci -m third
  $ rm does-not-exist-in-1
  $ hg diff -r 1
