af08f68448 Fix JACK process callback handling 
The callback apparently can't be set after activation, but we can't allocate
the ring buffer until after activation when the callback is already getting
called. An ugly flag it is, then, I guess.

6f1c853397 Don't allocate the ring buffer for JACK before activation 
It seems the JACK server can send buffer size change events during device reset
and wait on it, which causes a failure since the change event can't be
processed during a reset. It's otherwise impossible to safely disable the
change event callback during a reset since the lock is already held and the
callback can be waiting to acquire it. The only guarantee we seem to have is
the event callback won't be invoked after jack_activate succeeds.

So instead, the buffer size can be queried after jack_activate and the ring
buffer allocated then, instead of using an event callback. This does mean the
buffer size can change with a start() call, but it's better than a failure to
start.

a671c02b0b Try harder to find a matching WASAPI configuration 
As long as the lowest channel bits match the enabled bits for a given
configuration, higher bits from any extra channels can be ignored since they
can be skipped.

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.

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