The great header shift: It didn't make sense to regenerate headers for the same module for every target (boot/kernel/user) it appeared in. And now that core headers are out of src/include, this was going to cause problems for the new libc changes I've been working on. So I went back to re-design how module headers work. Pre-requisites: - A module's public headers should all be available in one location, not tied to target. - No accidental includes. Another module should not be able to include anything (creating an implicit dependency) from a module without declaring an explicit dependency. - Exception to the previous: libc's headers should be available to all, at least for the freestanding headers. New system: - A new "public_headers" property of module declares all public headers that should be available to dependant modules - All public headers (after possible processing) are installed relative to build/include/<module> with the same path as their source - This also means no "include" dir in modules is necessary. If a header should be included as <j6/types.h> then its source should be src/libraries/j6/j6/types.h - this caused the most churn as all public header sources moved one directory up. - The "includes" property of a module is local only to that module now, it does not create any implicit public interface Other changes: - The bonnibel concept of sources changed: instead of sources having actions, they themselves are an instance of a (sub)class of Source, which provides all the necessary information itself. - Along with the above, rule names were standardized into <type>.<ext>, eg "compile.cpp" or "parse.cog" - cog and cogflags variables moved from per-target scope to global scope in the build files. - libc gained a more dynamic .module file
