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.
