avio: add avio_skip macro

Browse Source 
This is a substitute for the url_fskip function that was deprecated by
commit 0300db8ad7. avio_fskip is provided to
improve demuxer code readability. It distinguishes the act of skipping over
unknown or irrelevant bytes from the standard avio_seek operation.
