dvdplayer: Allow multithread decoding for hi10p content by default

This allows decoding of some hi10p material on e.g. AMD Fusion with
both cores at the max. This introduces a new advancedsetting named
disablehi10pmultithreading to disable hi10p decoded multithreaded.

intents: Add a java class for listening to intent broadcasts
intents: hook up a JNI_OnLoad for finding our java functions

This should be extended to do lots more, so that we can quickly add java code
and access it from native, without the mess that is jni.
droid: remove the stateful life-cycle manager

Simply properly react to messages instead. This ends up being much cleaner and
more straightforward.

There were many problems with the old life-cycle code:
- It based all decisions on gain/loss of focus, which is incorrect, as that
  pertains to input rather than windowing.
- Due to the above, there were many race conditions.
- The startup/teardown were convoluted
- It was a mix of examples, a stateful one where the app keeps track of status,
  and a stateless one mainly handle by appglue. Since we really only care about
  a handful of events (startup/exit/newwindow/destroywindow mainly), stateless
  is the way to go for us.

This fixes random black-screens, fixes, and crashes when starting XBMC as a
launcher.
Fix double append to m_curlAliasList bug by NULL check.
Fix memory leak, Exists/Stat allocated resource not released correctly.
