[Qemu-devel] [RFC PATCH 1/4] tests: Introduce Docker based tests

[Fam Zheng <famz@redhat.com>]

A new group of targets to spawn docker instances for testing is added:

- "make docker" will spawn each available docker image and run all
  available tests under tests/docker.

- "make docker-foo" will spawn image foo and run all available tests.

- "make docker X=bar" or "make docker-foo X=bar" will limit the tests to
  only matching pattern "bar".

If the docker images (tagged like qemu:foo) don't exist, the make
command will automatically build them with foo.docker.

MAKEFLAGS is passed into the container.

Breaking down the tests/docker directory:

- *.docker in Dockerfile format define the environment in which tests
  are run.

- *.sh are testing scripts to be executed by "run".

- "run" is the entry script to run inside the container.

- Anything else are indirectly used or documents.
