Currently we attempt to skip building container images if the commits do
not involve changes to the dockerfiles or gitlab CI definitions.
Conceptually this makes sense, but there is a challenge in the real
world implementation of this in gitlab.
In the case of a CI pipeline triggered from a merge request, GitLab
knows the common ancestor of the merge request and the main git repo,
so it can trivially determine if any of the commits associated with
the MR change the dockerfiles.
In the case of a CI pipeline triggered from a push to a branch, it is
much more difficult. There is no concept of a common ancestor in this
case. Instead GitLab looks at the set of commits in the git push event.
On the surface this may sound reasonable, but it doesn't take into
account that a push event does not always contain the full set of
patches from a branch.
For example, consider pushing 5 commits, one of which contains a
dockerfile change. This will trigger a CI pipeline for the
containers. Now consider you do some more work on the branch and push 3
further commits, so you now have a branch of 8 commits. For the second
push GitLab will only look at the 3 most recent commits, the other 5
were already present. Thus GitLab will not realize that the branch has
dockerfile changes that need to trigger the container build.
This can cause real world problems:
- Push 5 commits to branch "foo", including a dockerfile change
=> rebuilds the container images with content from "foo"
=> build jobs runs against containers from "foo"
- Refresh your master branch with latest upstream master
=> rebuilds the container images with content from "master"
=> build jobs runs against containers from "master"
- Push 3 more commits to branch "foo", with no dockerfile change
=> no container rebuild triggers
=> build jobs runs against containers from "master"
The "changes" conditional in gitlab is OK, *provided* your build
jobs are not relying on any external state from previous builds.
This is NOT the case in QEMU, because we are building container
images and these are cached. This is a scenario in which the
"changes" conditional is not usuable.
The only other way to avoid this problem would be to use the git
branch name as the container image tag, instead of always using
"latest". The downside of this approach is that the user's gitlab
registry will grow significantly until it starts to trigger
GitLab's automatic deletion policy. Every time the user starts
a new branch they will have to trigger a rebuild of the container
images. Given this, we might as well just drop the conditional
and always build the container images. Most of the time docker
will be able to use the layer cache to avoid the most expensive
part of the rebuild process (installing all the RPMs/debs/etc)

According to our support policy, Debian 9 is not supported by the
QEMU project anymore. Since we now switched the MinGW cross-compiler
builds to Fedora, we do not need these Debian9-based containers
in the gitlab-CI anymore, and can now also get rid of the "layer3"
container build stage this way.

According to our support policy, we do not support Debian 9 in QEMU
anymore, and we only support building the Windows binaries with a
very recent version of the MinGW toolchain. So we should not test
the MinGW cross-compilation with Debian 9 anymore, but switch to
something newer like Fedora. To do this, we need a separate Fedora
container for each build that provides the QEMU_CONFIGURE_OPTS
environment variable.
Unfortunately, the MinGW 64-bit compiler seems to be a little bit
slow, so we also have to disable some features like "capstone" in the
build here to make sure that the CI pipelines still finish within a
reasonable amount of time.

The tests/docker/* wildcard seems to only match the files that are directly
in the tests/docker folder - but changes to the files in the directory
tests/docker/dockerfiles are currently ignored. Seems like we need a
separate entry to match the files in that folder. With this wildcard added,
the stages now get re-run successfully when something in the dockerfiles
has been changed.

Instead of building the docker files directly use the same docker.py
scripting as we do for building locally. This should help ensure we
use the exact same steps and allow us to cache properly when building
locally.
To get this working you have to have a fairly recent docker binary
otherwise you will see the error message:
=> ERROR importing cache manifest from registry.gitlab....

We happily use all the cross images for both cross-building QEMU as
well as building the linux-user tests. However calling docker from
within docker seems not to work. As we can build in Debian anyway why
not include an image that has all the compilers available for
non-docker invocation.

We have a number of container images in tests/docker/dockerfiles
that are intended to provide well defined environments for doing
test builds. We want our CI system to use these containers too.
This introduces builds of all of them as the first stage in the
CI, so that the built containers are available for later build
jobs. The containers are setup to use the GitLab container
registry as the cache, so we only pay the penalty of the full
build when the dockerfiles change. The main qemu-project/qemu
repo is used as a second cache, so that users forking QEMU will
see a fast turnaround time on their CI jobs.
