cgo: refactor

Browse Source 
This is a large refactor of the cgo package. It should fix a number of
smaller problems and be a bit more strict (like upstream CGo): it for
example requires every Go file in a package to include the header files
it needs instead of piggybacking on imports in earlier files.

The main benefit is that it should be a bit more maintainable and easier
to add new features in the future (like static functions).

This breaks the tinygo.org/x/bluetooth package, which should be updated
before this change lands.
