[ADDED] Build with GitHub actions

[levb]

• For all PR events: all tests with gcc and clang, coverage, all sanitize modes, in Debug mode against main
• For all push events (including in PRs) all tests with gcc and clang, in Release mode, against main
• For pushes to main, release_* check against the latest server release, v2.9.11; older C compilers, TLS OFF, Streaming OFF
• Also added backtrace in tests on linux

Coverage checks should work for new PRs once this is merged to main and ran there.

@kozlovic Can you please also review? I'll run it in parallel with Travis for a while. The "Release" build can be tested on your own branch if you remove the branch: main,... from on-push-release.yml

[kozlovic]

Unless it is required, I would comment the verbose flag from CMakeLists.txt and maybe change the size_t to int (unless you have some doc that shows that it ought to be a size_t.

@levb By the way, I forgot to comment at the time, but some of the matrix tests are run 3 times, is it intentional or was it part of some debugging/test at the time you were writing the PR? There is nothing wrong running each test 3 times in a row, it may catch some issues that are timing based, but just wanted to make sure it was intentional.

Intentional, so see the flappers more often.
