Size Packet Negotiation Facility dissection has 2 errors.

The decoded value of Size Packet shown as "From the calling DTE" is the value
of "From the called DTE".

When the size packet to negotiate has any of 512, 1024, 2048 or 4096 bytes, the
value shown decoded is erroneus.



The patch attached also includes new decoded facilities:

- Extended CUG selection.
- Extended access outgoing CUG selection.
- Extended RPOA selection.
- NUI selection.

- Charging info selection.
- Call dureation.
- Segment Count.
- Monetary Unit.


Capture files test the new facilities.

pktsize.pcap    -> Real capture.
bugpktsize.pcap -> Cooked, shows the error.
cugext.pcap     -> Cooked, test Ext. CUG facility.
charge.pcap     -> Cooked, test all charging info facilities included
rpoaext.pcap    -> Cooked, test Ext. RPOA facility.
nui.cap         -> Cooked, test NUI facility.


Sorry my English.
