Building on https://codereview.chromium.org/59943011/ this patch allows the
avd.py script to launch emulators targeting any API level and adds mips support.
As per discussions with Armand and Maria, I've also removed the canned configs
in favor of a template system that we can trivially update as new flavors
emerge. This avoids needed to create a /<api-level>/<arch> directory structure
now that --api-level is available.

That looks great.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a lowly provisional committer, _not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.
