Colin Cross 127d2eae8b Import globbing from Soong ... Add globbing with dependency checking to blueprint. Calling ModuleContext.GlobWithDeps or SingletonContext.GlobWithDeps will return a list of files that match the globs, while also adding efficient dependencies to rerun the primary builder if a file that matches the glob is added or removed. Also use the globbing support for optional_subdirs=, subdirs= and build= lines in blueprints files. The globbing slightly changes the behavior of subname= lines, it no longer falls back to looking for a file called "Blueprints". Blueprint files that need to include a subdirectory with a different name can use build= instead of subdir= to directly include them. The Blueprints file is updated to reset subname="Blueprints" in case we want to include subdirectories inside blueprint and the primary builder has changed the subname. Also adds a new test directory that contains a simple primary builder tree to test regeneration for globbing, and runs the tests in travis.
