Abis over IUA capture

Build Information:
Build 1.10.1 for Windows 8 64-bit
--
When GSM Abis packets are contained in IUA/SCTP packets the Abis messages are
decoded incorrectly. This happens because Q.921 SAPI values are used by default
in DLCI Parameter of IUA packets.  It's impossible to use the GSM SAPI values
in DLCI Parameter of IUA packet (as in LAPD protocol settings). The ability to
use GSM SAPI values should be added to IUA protocol settings.
