* Get rid of recursive `make` when building the node binary. An earlier commit makes GYP write out rules that we can use for proper dependency tracking. * Use module name 'binding' in addons.md and addons-napi/*/binding.gyp. This massively simplifies the logic for generating the build rules. * Check in auto-generated add-on tests from `doc/api/addons.md`. The files change rarely and generating them dynamically causes no end of race conditions and special-casing during the build.
