The functions used to interact with the asynchronous buffer currently are
located in the drivers.c souce file. The only function driver.c uses is
comedi_buf_alloc().
For aesthetic reasons and to help maintainability, separate all the
asynchronous buffer functions out to a new comedi_buf.c source file.
Do a bit of cleanup of the comedi_buf_* functions to clarify them,
v2: rebased and reordered a bit based on next-20130108
fixed a couple int/unsigned int issues pointed out by Ian Abbott
