http_streamer: General refactor making use of new API

* Use BUrlProtocolRoster instead of BFileRequest.
* Removed HTTPMediaIO custom code that now inherits
BAdapterIO and make the whole thing more simple.
* It work with some formats (flv, mp3, mkv) but ffmpeg fail
on others (mp4, 3gp).
* GetSize needs improvements.
