previously some state variables were reused for this
purpose which caused hidden bugs in multi device
implementation, this would cause issues with reloading
the jack server in certain conditions
now separate variable is used and the driver correctly
evaluates sample bytes and format

error code can now be checked making error handling more
explicit
this change also fixes confusing log in case of idle mode of
operation
the specific error code numbers are not significant because they
were never used in handling errors and in general there is error
log printed each time error occurs

'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.

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
