Report stalled event correctly for <video>

BUG=20127
BUG=13568
TEST=Opens a web page, stalled event should be fire only if network
     is actuall stalled.

What this patch does:
1. Report Loading / Idle according to whether we are actively
   receiving data in the BuffereResourceLoader. This is done by
   signaling the network events to BufferedDataSource and then
   to the media playback pipeline.

2. Report byteLoaded() as the last byte position buffered. This
   will enable an actual ticking progress for the progress event.
   With this value actually ticking, stalled event is suppressed.
