Previously we treated kernel/, system/, and third_party/ as overlays on a shared namespace. This required the concept of "canonical" module names, and a lot of complexity to ensure that things didn't collide and the build worked. This change gets rid of that, no longer passes -I to make, so that include directives from our *.mk files do not magically wildcard across various paths, etc. The most user-visible change is that everywhere where a module name is specified (MODULE_DEPS, MODULE_LIBS, etc), full module names like kernel/lib/io or system/ulib/mxio must be used instead of previously-allowed "short" names like lib/io and ulib/mxio. The build output still has a similar shape, but the first segment of the module path (kernel/, system/, or third_party/) is no longer elided under $(BUILDDIR) Change-Id: I525aba1da1c86eb7a86007bddc669f7eeebfedd5
