e82145aeae spa-resample: don't flush too much 
Also clamp the amount of input samples we push when flushing. do several
rounds of zero pushing until we have flushed enough.
Handle the cases where no input is needed or no output is generated.

Fixes crashes when downsampling from 96000 to 1000 Hz or so.

ed88cad583 spa/alsa-udev: Check accessibility of pcm devices as well 
The order of attribute changes is random, so it's possible that controlCX is
accessible before the other devices, which marks the device as available but it
actually fails to open. Only consider the device accessible if both control and
PCM devices can be accessed.

This requires reacting to ATTRIB changes of pcm devices as well now.

Fixes #2534

52281b9a7e alsa: check the offset against the size of the buffer 
We need to check the last offset against the size of the buffer, not the
remaining size in the buffer.

When the writing is split, this could cause the buffer to be reused
wrongly.

See #2536
