return number of bytes written. Return -1 if waitforspace returns false
and no bytes have been written so far.
(fhandler_dev_dsp::Audio_out::waitforspace): Change return type to bool.
Handle O_NONBLOCK. Make waiting loop interruptible and cancelable.
Return false in any of these cases, otherwise true.
(fhandler_dev_dsp::Audio_in::read): Set returned nBytes to -1 if
waitfordata returns false and nothing has been read so far.
(fhandler_dev_dsp::Audio_in::waitfordata): Change return type to bool.
Handle O_NONBLOCK. Make waiting loop interruptible and cancelable.
Return false in any of these cases, otherwise true.

parameter.

nonblocking case. Drop useless waiter variable. Rewrite wait for
input_available_event to use a switch statement. Handle timeout and
failure more gracefully. Make restartable and cancelable. Rewrite
wait for input_mutex to use WFMO and a switch statement. Handle
timeout and failure more gracefully. Make restartable and cancelable.

(fhandler_serial::raw_write): Wait for write to succeed if O_NONBLOCK
is not set. Add signal handling and cancelability.
