* add run.using = 'run-task' for native-engine
* modify run-task to run on OS X
- not as root
- without assuming /home/worker (using ~ and os.expanduser instead)
- hg is in /usr/local/bin on OS X; trust the PATH
* add_build_dependency isn't docker-worker specific, so just rename
* support_vcs_checkout modified to omit caches on native-engine
* don't download fingerprints on OS X; these hosts are configured with
the proper fingerprint via puppet

Instead of every file trying to get the top source directory having an
ad-hoc definition that gets wrong if the files gets moved around for
some reason, define it in a more central location.

This allows to find them and optimize them out during the taskgraph
optimization phase, and will allow to get toolchain artifacts through a
mach command for developers.
The index path is generated similarly to git trees or mercurial
manifests, and allows to find the right task corresponding to the the
contents of the files in the task `extra.resources` along the toolchain
scripts.
`when.files-changed` is not used when a task has index paths because we
need tasks to happen independently of whether there were changes to
those files when the index or artifacts expire.
