Refactor ListenerMultiplexer with new capabilities

-Store tag string in multiplexer rather than duplicating in every
registration.
-Add support for failure callbacks at listener operation submission
time, in addition to within the listener operation itself.
-Extract request out of ListenerRegistration and into subclass, so that
the multiplexer does not need to have any knowledge of requests.
-New multiplexer specific execute and failure callbacks within
registrations objects, with strongly typed listener operation objects.
-Fixed resetService() to work properly even if the service is still
registered.
-Added registration info as an argument to registerWithService() so that
this doesn't need to be duplicated if a client wants access to this
information.
-Narrow exception handling so that only the proper exception
(RemoteException for binder calls for instance) results in registration
removal, and other unexpected checked exceptions should still crash the
process.
-Various other minor fixes.

Test: manual + presubmit
