alsa-compress-offload: Add device object and udev based autodetection

Browse source 
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.
