pvr: Pass selected item to menu hooks

Currently it is not possible to retrieve any information about the
selected item in the addon's menu hook callback. Therefore menu
hooks can only trigger actions per category, but not per item.

This patch removes this limitation by extending CallMenuHook with
an item parameter representing the type (PVR_MENUHOOK_CAT) and the
data of the currently selected item. The type PVR_MENUHOOK_UNKNOWN
indicates that no selection is available (as for settings hooks).

jni: allow passing java String[] via std::vector<std::string>
jni: fix get_static_field when using a cached class
jni: pass null strings as null objects, as java expects them
jni: add Cursor class
jni: add stub for ContentResolver class and hook it up to Context
jni: build new files
jni: add a few functions needed for parsing intents
jni: add stubs for MediaStore statics
jni: Add a top-level static member cache

Some static members are useful before their class is instantiated, so we must
resolve them some time before first use.

Any class can be added here so that they are cached when the activity is
created. The linker should strip away any that aren't used.
jni: register for music/movies and common protocols
jni: move the rest of the static members into PopulateStaticFields functions
jni: create GetAppInstance() and use it rather than passing a copy around
