This patch adds "LPBK" buttons to the output strip
channels allowing to toggle the hardware output
loopback state.
Efforts were made to hide the buttons for not yet
enabled devices but due to difficulties in implementation
was cancelled for the time being. Should it be a no-go
efforts should be made to fix this and hide them,
although I would think fixing the driver for other
devices would be an effort with much more merit.
This is currently only enabled for HDSP9632 devices
with following driver patch:
da2a040ee7
We check whether the system has the kernel patch
applied by calling `HDSPMixerCard::supportsLoopback()`
and if not these buttons remain gray (off) and do
nothing when clicked.

When switching cards, all current settings are lost. To have a place
where to store them, let's add a virtual 9th preset which can be used as
a temporary scratch pad.

If three (or more) RME cards are installed in one box, hdspmixer will
try to open a non-existing 4th card, causing an error in snd_ctl_open
and finally terminates itself.
cards[] is a static array, and one must not read beyond the last
element. The solution is far from elegant, however, it's a rather
unintrusive change.

Move channelmappings into one place (channelmap.h). Also, use "aes32"
when referring to the card itself to avoid confusion and to be coherent
with the remaining naming scheme.

It seems the PCIe (AES) and PCI (AES32) versions behave the same, so we
can kill two birds with one stone.
