If the record target doesn't care about channel count, set it to the device count

The aforementioned merge happened

Take absolute value for peak!

I forgot these were currently only in a branch of bqresample - comment for the moment until later merge there

Make these parameters explicit

Ensure latency is reported to application in terms of the source sample rate, not the target one

Fix incorrect stream reference for record latency, resulting in crash when started in record-only mode

Fix crash when started in record-only mode

Fix typo in comment

Doc notes

Copyright dates

Fix uninitialised member

Remove vestigial includes from earlier debugging

Ensure the loop thread knows it should give other threads a chance, when awoken explicitly

Avoid compiler warnings (the semicolons were spurious)

A little more logging, especially when in debug mode

Minor log improvement

Move JACK to end of listing

Minor debug output

Don't blow up if the application channel count is zero; instead wait for the system to set one. Also add log callbacks
