This patch proceeds more abstraction of PCM read/write loop codes. For both interleaved and non-interleaved transfers, the same copy or silence transfer code (which is defined as pcm_transfer_f) is used now. This became possible since we switched to byte size to copy_* and fill_silence ops argument instead of frames. And, for both read and write, we can use the same copy function (which is defined as pcm_copy_f), just depending on whether interleaved or non-interleaved mode. The transfer function is determined at the beginning of the loop, depending on whether the driver gives the specific copy ops or it's the standard read/write. Another bonus by this change is that we now guarantee the silencing behavior when NULL buffer is passed to write helpers. It'll simplify some codes later.
