avformat_open_input() error reporting can be misleading

Attemping to use avformat_open_input() without having called av_register_all() first results in ENOENT "No such file or directory". As an ffmpeg newcomer this was very confusing and I had to dig in to the guts of libavformat with a debugger before I figured out what was going on.

Attached is a patch that introduces a new error code with an informative error message for this case.

Ive solved this a bit differently, as i think the error code is not so helpfull, it still requires quite a bit of indirection. That is "why does it fail? what does this error code mean? ..."
