fa19d3259b Use build container id rather than tagging builds 
This means that multiple builds will not conflict, so we can
remove the lock from the CI. Also quieter when no errors.

Some still left to do, only done the ones used in build and CI
initially. Some of the others will be cleaned up anyway later.

821b329f7b transfused: add separate FUSE notify channel to avoid deadlock 
This adds a new notify channel to the transfuse protocol. It is not
optional yet but could be made to be optional. A notify protocol and
notify channel are required because writing FUSE response messages to
the FUSE device has different semantics from writing asynchronous
notifications. In particular, response message writes only error on
malformed messages, do not take locks, and do not block. In contrast,
asynchronous notifications can error under normal conditions
(e.g. invalidating a cache entry that doesn't exist), can take locks
during the write call, and can block.

If responses and notifications occur in the same thread, the file system
can become deadlocked when syscalls lock resources waiting for a
response and a notification is written that blocks attempting to acquire
those same locks. The response that would unlock the contended lock
could be queued behind the notification write but the notification write
can't unblock until the response is written in the future. This patch
enables file systems to avoid that fate by offering a secondary channel
on which to send notifications.

c75eb93d1c transfused: distinguish export requests from mount requests 
We distinguish export suitability requests from bind mount suitability
requests in the transfuse control protocol. This distinction allows us to
permit both bind mounts of empty directories and export mounts onto empty
directories. Addresses docker/pinata#4213.

5165a6c795 Add || true to the docker rmi invocations in the clean target 
Linux xargs calls the command with no arguments if it gets no inputs, which
`docker rmi` complains about. It provides -r / --no-run-if-empty to prevent
this but unfortunately this isn't supported on OSX.

Ignore errors from `docker rmi` so that `make clean` will keep going and clean
up later stuff.
