Major changes:
Run 4 build configurations in parallel with Valgrind on Linux
Add test failure detection verification (meta-test)
Port allocation per build to prevent conflicts in parallel runs
Add --coverage-only flag for dedicated coverage builds
Code quality:
Add TEST_GROUPS constant, CMOCKA patterns, helper functions
Organize ci-build.sh into sections
Split functional tests into 4 parallel groups and add check-functional-parallel target (~3x faster CI runs).
Add branch-aware LCOV coverage reporting with new --enable-coverage option and lcov summary in CI pipeline.
Enable ccache via -C configure flag for faster recompilations.
Install lcov in all Docker images and use --depth 1 git clones + parallel make -j$(nproc) for quicker container builds.
Update CONTRIBUTING.md with instructions for parallel test groups and adding new ones.
All changes are tightly related CI/performance improvements developed in sequence. No external service uploads (e.g. Codecov skipped due to Gitea incompatibility).
Introduce separate jobs to test C (Doxygen) and Python (Sphinx) API documentation generation. Ensures build failures are caught early, as API changes often produce warnings that developers miss without automated checks.
Current setup of the infratstrcture with DIND
was causing issues with volume binding,
leading to a false-positive error on code formatting check.
This commit addresses the issue by removing dependency on a container,
but at the same time it limits choice of formatting version.
This fix does not address the underlying issue with the architecture.
As an additional change, package versions are updated.
TW curently has problems:
```
Problem: the to be installed sqlite3-devel-3.39.2-1.2.x86_64 requires 'libsqlite3-0 = 3.39.2', but this requirement cannot be provided
not installable providers: libsqlite3-0-3.39.2-1.2.i586[repo-oss]
libsqlite3-0-3.39.2-1.2.x86_64[repo-oss]
```
This reverts commit 5c5c453219.
And removes the old python(2) pull in.
For some reason we get:
`Package python3-embed was not found in the pkg-config search path.`
with python38-devel but not with python310-devel. Let's bump it to that
version.
Until they fixed this:
```
Problem: the to be installed ncurses-devel-6.3.20220604-20.1.x86_64 requires 'libncurses6 = 6.3.20220604-20.1', but this requirement cannot be provided
Problem: the to be installed gtk2-devel-2.24.33-2.8.x86_64 requires 'pkgconfig(cairo)', but this requirement cannot be provided
Problem: the to be installed ncurses-devel-6.3.20220604-20.1.x86_64 requires 'libncurses6 = 6.3.20220604-20.1', but this requirement cannot be provided
not installable providers: libncurses6-6.3.20220604-20.1.i586[repo-oss]
libncurses6-6.3.20220604-20.1.x86_64[repo-oss]
Solution 1: downgrade of libncurses6-6.3.20220604-20.2.x86_64 to libncurses6-6.3.20220604-20.1.x86_64
Solution 2: do not install ncurses-devel-6.3.20220604-20.1.x86_64
Solution 3: break ncurses-devel-6.3.20220604-20.1.x86_64 by ignoring some of its dependencies
```
