stream: set errno to the current error

Browse source 
Make the state_changed event and _get_state() function set errno with
the current error value if the state is in error, so that application
can use this to give more detailed error reporting.

Use this in alsa, v4l2 and pulse to give some other error codes than
EIO.

Fixes #4574
