Cache jclass/jmethodID/jfieldID references
This patch introduces an initialization framework, which tracks required references to Java classes and methods. It works by declaring classes and their constructor signatures, which are linked into a singly-linked list when the .so initializers are run. Once JNI_OnLoad() is invoked, this list is walked and all classes and their initializers are resolved. These are then used while the library remains loaded. Once JNI_OnUnload() is called, global references are released, so we can cleanly unload. The class declaration results in static utility objects being emitted in the scope of the declaration, hence to allocate an object or an array of objects is done via simple calls.
