JSON APIs on hg.mozilla.org

I added a feature to Mercurial 3.4 that exposes JSON from Mercurial's various web APIs. Unfortunately, due to the presence of legacy code on hg.mozilla.org providing similar functionality, we weren't able to deploy this feature to hg.mozilla.org when we deployed Mercurial 3.4 several weeks ago.

I'm pleased to announce that as of today, JSON is now exposed from hg.mozilla.org!

To access JSON output, simply add json- to the command name in URLs. e.g. instead of https://hg.mozilla.org/mozilla-central/rev/de7aa6b08234 use https://hg.mozilla.org/mozilla-central/json-rev/de7aa6b08234. The full list of web commands, URL patterns, and their parameters are documented in the hgweb help topic.

Not all web commands support JSON output yet. Not all web commands expose all data available to them. If there is data you need but isn't exposed, please file a bug and I'll see what I can do.

Thanks go to Steven MacLeod for reviewing the rather large series it took to make this happen.
