As part of this, in alsa-udev.c, certain structures and variables referred to as "device" are renamed to "card". Otherwise, there is ambiguity, since "device" can mean a udev device, an SPA device, a compress-offload device, a PCM device etc. Also, replace "card id" with "card number" to emphasize that these integers are not actually SPA object IDs.
