730c964029 Allow calling BackendBase::open multiple times on playback devices 
It will not be called while the device is running. If the first call succeeds,
a subsequent call that happens to fail must leave the existing device state as
it was so it can be resumed.

This is a rough first pass. It will fail when trying to re-open the same device
which can only be opened once (for instance, with direct hardware access, on
hardware that doesn't do its own mixing). Some backends won't guarantee the new
device is usable until the reset() or start() call.

d08d6b18c4 Ceil the scaled buffer size instead of round 
The result has to be large enough to get the original requested size from it.

2e6a55a87c Handle padding between device sample frames 
The padding must be constant and sample type aligned (e.g. some fixed multiple
of two bytes between the start of two consecutive frames for 16-bit output).
The intent is to always have the ability for stereo output with WASAPI even if
the device has some other unsupported configuration, as long as front-left and
front-right exist.

b687e952ef Make C callbacks noexcept 
No telling what would happen if exceptions managed to get back into presumably
C-based callers.

963580c2d5 Never return null from CreateRingBuffer 
Allocation failure would already throw a bad_alloc anyway, now a size overflow
throws an exception too.
