* slimmer stack frames in encoder

* reformat polyfil.js and decode_test.js
* re-enable Js build/test
* improve decoder performance
* rewrite dictionary data in Java/Js to a shorter uncompressed form
* improve dictionary generation tool
* add autotools build
* separate semantic and ABI version
* extract sources.lst (used by CMake and Automake)
* share pkgconfig templates (used by CMake and Automake)
