Merge branch 'gitlab-ci' into 'master'

Set up GitLab CI

This merge request is now ready. Build with gcc and clang works, all tests pass except tests.aconversion.sh (see #83). The last complete build is [pipelines/917](https://gitlab.fit.cvut.cz/travnja3/automata-library/pipelines/917).

Jobs may sometimes fail due to not enough space on disk, I’m gonna fix this problem soon.

See merge request !25

+# NOTE #1: Our GitLab CI runs jobs inside Alpine Linux container by default.
+#
+# NOTE #2: Keep in mind that each job (e.g. test-gcc) is executed in a separate
+# isolated environment (it may be even on different machine). There are no
+# files implicitly passed between jobs or stages, only artifacts and maybe
+# cache (depends on configuration).
