[Guillaume Chazarain <guichaz@xxxxxxxx>]

Hi,

Please find attached a patch to fix some bugs in the armagetronad 
dissector. More specifically:

* Update the descriptors to armagetronad-0.2.8.2.1, the file
src/network/Makefile.in does not exist anymore in the armagetronad 
source code.
* Ensure the printed data is null terminated.
* Avoid guint16 overflow because of the '* 2'.
* Remove a statement with no effect (data = NULL).

Thanks.

Guillaume
