Not in most cases - and even the ones that are are provided as something 
to be plugged into Ethereal.

Not conveniently, other than writing your own application to use 
libethereal.  You'd have to do your own work to fit it into your 
application otherwise.

If you link our GPLed code into your application, your application must 
be GPLed.  No exceptions.  Using them separately from the rest of 
Ethereal would make no difference.
