ALSA has PCM interface to transfer data frames. In userspace, there're some implementation to utilize this interface to produce application programming interface; alsa-lib (libasound) and tinyalsa. However, it's possible to use the interface with raw I/O operations. This commit adds an common interface to transfer data frames for this program, named as 'xfer'. This internal interface is designed for users to select several backend for data transmission. This includes some functions expected to be called by main program just for data transmission. In an aspect to maintain PCM substream, suspend feature is required to handle a pair of SIGTSTP/SIGCONT UNIX signals.
