Preparation for creating an alternative non-crazy linker based chromium Linker: - Convert Linker from pure static into a singleton class. - Split into an abstract base class containing (expected) common code, and (for now) a single concrete subclass that implements the current crazy linker based loading of libchrome.so. - Update client code to handle the singleton getInstance() requirement and class name changes. - Modernize logging. Later changes will introduce a second concrete Linker subclass that is free of crazy linker code, for Android platform system linkers that handle packed relocations, load from apk, and shared relro natively.
