cleaned up LOTS of build-related stuff
There were a lot of things that were relying on transitive #include
and/or gyp dependencies that I fixed.
I also got rid of all references to libaos and a lot of references to
aos/aos_core.h and its build target.
This in preparation for removing libaos completely.
