[HICN-653] Cleanup build scripts.

Main changes:
- Next VPP version is now counted 4 months (instead of 3) from the current one
- CMake will now use Ninja as generator
- Build functions are gathered under build/functions.sh and they are shared
  instead of being duplicated in build-extras and build-packages
- Various bug fixes for dependencies and versioning.
