The version currently in-tree is pretty old. Updating with the latest gives us compatibility with the latest versions, Python 3 compat, and some better metrics.

Also needed this is apparently blocking bug 1561956 now.

This commit vendors robustcheckout from commit 584993820a97df in
version-control-tools. Updates include the removal of some dead code,
compatibility with the latest Mercurial, and Python 3 compatibility.

This one has nothing to do with Docker image builds, and is almost certainly not related to my changes.

The failure here has to do with a missing ip, ifconfig or ipconfig command. robustcheckout doesn't use any of these binaries - it's just a Mercurial extension. I doubt there's any relation.

This is just a timeout connection to FF-CI taskcluster. robustcheckout has nothing to do with this.

Since robustcheckout likely isn't affecting any of these failures (or at least, if it is, I have absolutely no idea how at this time), I'm going to try and land once more. If it needs a backout I'll debug further on Monday.
