4.0 regression: ALSA unusable as secondary input source

ALSA as secondary isource triggers the error Invalid url passed to the "input-slave" option and is ignored. This makes recording audio from an analog audio/video (V4L2) source impossible.

Most probably caused by bbdaa0b6.

Even worse, tried it with alsa:// or alsa://null and it just segfaults because a NULL path from the url parser isn't handled properly.

@Courmisch Could you share the exact MRL that cause vlc_UrlParse to fail though ? I have trouble reproducing the same behavior as yours.

AFAIK, literally any ALSA MRL will fail. See also fora.

Well OK, I suppose dumb stuff will not fail, but even the most basic plughw/hw input will.
