malloc types into a structure, a pointer to which is passed around,

16-bit mono recording seems to work OK. 16-bit stereo recording
is missing the left channel for reasons unknown, fixes welcome.
8-bit recording still unsupported.

Add a quirk flag for hardware that has left and right channels reversed
(currently the COMPAL 38W2 a.k.a. Dell Inspiron 5000e)
Clean up PCM channel initialization and add channel swapping option.
