Hydra build farm.

* Made the garbage collector a lot faster. It no longer computes the
...
complete set of live and dead paths before starting the actual
deletion, but determines liveness on demand. I.e. for any path in
the store, it first tries to delete all the referrers, and then the
path itself. This means that the collector can start deleting paths
almost immediately.

* Remove the --use-atime / --max-atime garbage collector flags. Many

(Linux) machines no longer maintain the atime because it's too

much time to make it practical.
