Reviewed by Youenn Fablet.

Pass to `bufferedchange` a dictionary containing the range added and removed
from the last operation on the source buffer.

Fly-by: remove the need for code to be conditional on both ENABLE(MEDIA_SOURCE) and
ENABLE(MANAGED_MEDIA_SOURCE), assume that if the latter is true, then
so is the first, as doing otherwise would be totally nonsensical.
