New issue 278 by [email protected]: SCCP XUDT bad possible length calculation
http://code.google.com/p/jss7/issues/detail?id=278

In SCCP stack when encoding XUDT message there is a bug when calculating max possible length of data field when callingParty / calledParty addresses filelds have big length. The result is XUDT message of some length is not segmented (as it is needed) and the message will be encoded in a wrong way and a peer can not decode this.
A solution is: adding an extra check:
max possible message data length must be <= 254 - (3 + calling party field length + called party field length)
