fix following warning by dynamically allocating memory:
dgnc_tty.c:583:1: warning: the frame size of 1060 bytes is larger than 1024
bytes [-Wframe-larger-than=]
Signed-off-by: Martin Kepplinger <mart...@posteo.de>

This is more of a question. Is this a desired solution to fixing such a
frame size warning?
thanks,
martin
