Alex Bennée 6e733da676 tests/docker/docker.py: add update operation
This adds a new operation to the docker script to allow updating of
binaries in an existing container. This is because it would be
inefficient to re-build the whole container just for an update to the
QEMU binary.

To update the executable run:

    ./tests/docker/docker.py update \
        debian:armhf ./arm-linux-user/qemu-arm

Alex Bennée 920776ea5e tests/docker/docker.py: check and run .pre script
The docker script will now search for an associated $dockerfile.pre
script which gets run in the same build context as the dockerfile will
be. This is to support pre-seeding the build context before running the
docker build.

Alex Bennée 504ca3c208 tests/docker/docker.py: support --include-executable
When passed the path to a binary we copy it and any linked libraries (if
it is dynamically linked) into the docker build context. These can then
be included by a dockerfile with the line:

  # Copy all of context into container
  ADD . /

This is mainly intended for setting up foreign architecture docker
images which use qemu-$arch to do cross-architecture linux-user
execution. It also relies on the host and guest file-system following
reasonable multi-arch layouts so the copied libraries don't clash with
the guest ones.

Alex Bennée a9f8d03891 tests/docker/docker.py: docker_dir outside build
Instead of letting the build_image create the temporary working dir we
move the creation to the build command. This is preparation for the
later patches where additional files can be added to the build context
before the build step is run.

We also ensure we remove the build context after we are done (mkdtemp
doesn't do this automatically for you).

Fam Zheng 4485b04be9 tests: Add utilities for docker testing
docker.py is added with a number of useful subcommands to manager docker
images and instances for QEMU docker testing. Subcommands are:

run: A wrapper of "docker run" (or "sudo -n docker run" if necessary),
which takes care of killing and removing the running container at
SIGINT.

clean: Tear down all the containers including inactive ones that are
started by docker_run.

build: Compare an image from given dockerfile and rebuild it if they're
different.
