Summary [GStreamer] WebKitWebSrc fails to seek on response to qtdemux_pull_mfro_mfra()

Created attachment 384427 [details] Repro When playing a fragmented MP4 file of known size in pull mode, just after finding the first moof, qtdemux will try read the the last few bytes of the file to parse the `mfro/mfra` index calling qtdemux_pull_mfro_mfra(). If the entire file has not been buffered at this point by the downloadbuffer element, which is the case for big enough files, it will send a SEEK event to webkitwebsrc, which will never send data back. The attached file is a repro of the bug. The bug has been reproduced while serving the files with lighttpd. Note despite of the small size of the compressed test case, the video file decompresses to >1 GB (made this way to ensure the bug is hit easily and still fit in Bugzilla).

I am dealing with some source improvements, I think I can tackle this just after those.
