add support for the user_data parameter to espeak_synth

Browse source 
The user_data parameter is just a pointer that is passed into the
espeak_synth call that is passed back to the callback.  In native mode,
we are not using it since there is not a callback.  However, in alsa
mode, it will be used to indicate when a cancel was processed.
