Commits on Jun 30, 2020

  1. alsa: Add multi dev support 

    linux release 1.0

what was tested:
 - playing and recording from multiple devices
 - linking devices, fallback for case when some or all devices are not linked
 - xrun recovery

notes:
 - we should be using epoll instead of poll, ~ +1 manday to implement
 - solution can be simplified to remove doubling parameters for capture and playback
device, instead one struct for abstract "device" could be created that has parameter
capture or playaback, this would simplify code and reduce duplicate lines of code

  19. jack alsa: rework 'x' and 'c' options 

    'c' decides what state idle device should be put to during reload
api call, when this option is present logic is to 'close' the idle
device, otherwise leave it 'prepared'

'x' enables the idle devices check for jackd init phase, the check
will behave the same way reload api call check call behaves,
therefore the state of the device will depend on 'c' option, if 'x'
option is not provided, devices will be configured to 'running' state
during jack init.
