TCAP multi-ssn support - Githubissues

We need to update SS7 stack so it supports for "extra SSN" for a TCAP stack (now each TCAP stack instanse) contains only one SSN that it reuses.

We will need following updates:

1) new extraSsn field in TCAP stask

add (null by default) FastList TCAPProviderImpl.extraSsn;
getter / setter for this (only for time when stack is stopped)
when we start TCAPStack we will register several times the stack for all mentioned SSNs

2) new "int ssn" field in TCAP Dialog.

for incoming dialogs this field will be filled by CalledPartyAddress SSN.
for outgoing dialogs this field will be filled by CallingPartyAddress SSN (if 0 or unspecified value of SSN - then main TCAP stack SSN will be used)

3) TCAPProviderImpl.send(....) - add an extra parameter "int ssn" that will be used instead of "this.ssn" as localSsn for creating of outgoing SCCP message. Methods that invoke this message will take "dialog.ssn" value.

4) we need to make the same for TCAP-ANSI stack

5) we need to prepare WildFly and jboss templates for TCAP stack initializing with extra SSNs. For jboss 5 we have:

<parameter>
  <list class="javolution.util.FastList" elementClass="java.lang.Integer">
       <value>8</value>
  </list>
</parameter>

6) SMSC GW - we do not need to update code itself (SSN is also assigned properly) and "extra SSN 6" will be for incoming dialogs and will be filled automatic. We will need to update jboss-beans.xml file for that extra SSN and updates manual for configurinfg.

7) We need to add support for an extra TCAP number in SS7 Simulator. QWe will intrcodue it as a second "Local SSN" value at SCCP level.
