Code generation for extensions api

This is a preliminary code review for a code generator. The tool's purpose is to generate the tedious serialization code that needs to be written when defining a new extensions api. It generates from the json files in chrome/common/extensions/api.

As an example usage, chrome/browser/extensions/extension_permissions_api.cc has been changed to use a class generated from permissions.json.

The tool has been integrated into the build system and generates compiling and working code (for permissions.json at least)
