logcmdutil: rewrite jsonchangeset printer to be backed by jsonformatter

This is a bit slower than the original implementation, but I don't think
that would actually matter. It's still faster than full templating.

  $ hg log -Tjson -r0:5000 --time > /dev/null
  (orig) time: real 1.550 secs (user 1.500+0.000 sys 0.040+0.000)
  (new)  time: real 1.810 secs (user 1.740+0.000 sys 0.070+0.000)

  cf.
  $ hg log -Tdefault -r0:5000 --time > /dev/null
  time: real 4.980 secs (user 4.850+0.000 sys 0.130+0.000)
  $ hg log -r0:5000 --time > /dev/null
  time: real 2.340 secs (user 2.220+0.000 sys 0.100+0.000)
  $ hg log -r0:5000 -q --time > /dev/null
  time: real 0.750 secs (user 0.670+0.000 sys 0.070+0.000)

The test output changes because keys are sorted alphabetically.

  $ cat > abortcommit.py <<EOF

  $ hg init foo
  $ cd foo
  $ echo foo > foo
  $ hg add foo

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:

  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]
  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]

  $ cd ..
