The new media button receiver with only a pending intent (no component name) could be left hanging if the process that registered it went away. These semantically need to be tied to the calling process's lifetime; we now clean them up when the calling process goes away. Also added some additional cleanup of media button receivers when packages change (updated, cleared). And on top of that, a new "media" command for doing media things. Currently lets you send media keys and monitor remote display data. Oh and finally added a new BaseCommand base class for implementing these command line utilities.
