[Android] [PATCH] Add support for multiple video instances.

To use the NativeCrashHandler inside VLCApplication::onCreate I need to
statically load the dynamic libraries, which now are loaded in LibVLC.java.
Should I move this static block to NativeCrashHandler or to
VLCApplication::onCreate
as a normal init method?
Thanks
