waf-abi: auto-generate per-symbol versions from ABI files
This changes our version-script generation to use the ABI files that
are saved in git with each version number change of our public
libraries.
We use these ABI files to generate a linker version script that gives
the exact version number that each symbol was introduced. This
provides us with automatic fine grained symbol versioning.
