audio: ioctl to fetch snapshot of counters

There are 4 audio counters, and we've one ioctl() to get each. So userland has to call the ioctl() one by one, and must take care to handle cases when a counters are inconsistent (i.e. don't belong to the same time). Inconsistencies are extreamly rare produce so the code is hard to test. This

azalia: rework buffer position reporting code

This diff simplifies the code that reads the DMA pointer and calls the audio(4) driver accordingly. - use simpler (and less) data structures, which makes the code shorter. - if multiple interrupts are missed, call audio(4) as many times as we missed interrupts (unless the pointer wrapped,
