Reviewed by Youenn Fablet.

There were two existing methods used to notify the SourceBufferPrivate
that the MediaSource was ended (through a call to MediaSource::endOfStream()):
 - SourceBuffer::readyStateChanged
 - SourceBuffer::setMediaSourceEnded

and both were duplicated in SourceBufferPrivate classes, though the
SourceBufferPrivateGStreamer used setMediaSourceEnded, while the others
used readyStateChanged.
They conveyed the same information.

We remove SourceBuffer::readyStateChanged and adopt setMediaSourceEnded
everywhere.

Also, by recalculating the buffered range when SourceBufferPrivate is notified
we can remove the two IPC loops between the GPU process and the content process
simply to update at the end the buffered ranges.

Covered by existing tests, no change in observable behaviour.
