[Bug 28093] GetCurrentPadding must slowly decrease (MacOS)

An alternative solution path in order to preserve the simplicity and elegance
of the current buffer handling with Core Audio is to decouple GetCurrentPadding
from the Core Audio callbacks. Instead, padding would be controlled by
GetPosition, like some exclusive mode drivers seem to do with some versions of
MS-Windows, as my render tests show. (For shared mode, one would still wish to
apply deltas of padding by ceiling modulo 10ms period size.)
Alas, this requires to fix bug #28039 first.

We'd have something along
padding := min(duration, written - position)
to accommodate for latency delays > duration
