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.

  $ echo a > a
  $ hg ci -Am0

  $ hg -q clone . foo

  $ touch .hg/store/journal

  $ echo foo > a
  $ hg ci -Am0

Check that zero-size journals are correctly aborted:

#if unix-permissions no-root
  $ hg bundle -qa repo.hg
  $ chmod -w foo/.hg/store/00changelog.i

  $ hg -R foo unbundle repo.hg
  adding changesets
  abort: Permission denied: $TESTTMP/foo/.hg/store/.00changelog.i-* (glob)

  $ if test -f foo/.hg/store/journal; then echo 'journal exists :-('; fi
