Support building and testing with various sanitizers (currently only
ASan and UBsan are supported out of the box).

Hey!

I finally got some time to work on bus1/dbus-broker#281 (comment) and this is the first take. The idea is to run the test suite in the bus1/dbus-broker repository with a snippet like:

  ci-sanitizers:
    name: CI with Address and Undefined Behavior sanitizers
    uses: bus1/cabuild/.github/workflows/ci-c-util.yml@v1
    with:
      cabuild_ref: "v1"
      matrixmode: true
      sanitizers: "address,undefined"

Unfortunately, I can't easily test this without reconfiguring image locations and pushing everything where it needs to be, so any insight or comments are very welcome.

@mrc0mmand thanks! I was kind of going to send a PR like that but I wasn't sure how cabuild worked.

The idea is to run the test suite in the bus1/dbus-broker repository with a snippet like

I'm just spitballing but I wonder if the tests could be run directly on Ubuntu? As far as I can see https://github.com/bus1/dbus-broker/blob/main/.github/workflows/codeql.yml builds and analyzes dbus-broker outside of any images.

currently only ASan and UBsan are supported out of the box

Given that as far as I can see there is a job running the unit tests under Valgrind I think ASan and UBSan on top should be enough to catch all kinds of issues.

Anyway, I'd need to figure out how cabuild works before leaving meaningful comments here :-)
