* Cleanup versioning strategy
Currently, versioning is a mess. CMake and Meson have seperate build
version number storage locations, with no way of knowing you need to
have both. Plus, due to recent revisions the amalgamate script is broken
unless you build first, and may still be broken afterwards.
This PR fixes some issues with versioning, and adds comments clarifying
what has to be done when doing a release.
* Run clang format
* Update SOVERSION....
This forces consistency, since they will be re-generated whenever
a git operation alters CMakelists.txt. They are still in the repo
because users might not actually run cmake.
