This patch updates ESP8266 build system and code base as well.
- Removed unnecessary files.
- Decreased code size.
- Refactored jerry_{port, extapi, run}.c to make it more easy to handle.
- Readme.md is updated as well which contains detailed step by step description about how to set up environment and use JerryScript.
Finally, it solves the related issue #1375.
