         - Send RLC immediately even when in native bridge mode
         - Do not enqueue RLC coming from the network

         - Enable native bridge also when receiving the UUID via SIP header
         - Remove some debug CRIT messages and set a more proper log level

         - Fix typo when unlocking channel that resulted in deadlock
         - Defer clearing of the peer data until it is completely safe (next call)

           to give the ability to change RDNIS Presentation value for
           Transparent IAM

           - adding freetdm_iam_fwd_ind_isdn_access_ind (value must be 0 or 1)
             to modify forward call indicator's ISDN access indicator value in
             transparent IAM

           - adding freetdm_iam_loc_pres variable to disable LOC in transparent IAM
 		   - confirming freetdm_bearer_capability is working properly

           - redirect number in Transparent IAM
		   - redirect information in Transparent IAM
		   - called party number in Transparent IAM
           - adding incoming uuid to x-header to check loop calls

           - hardcode does not work in this matter

           - only available to SPIROU

           - take the DPC of the link and set it as OPC in x-header
           - this is what the user want's to have

         On SIG Down we must not fail a call instead try hunting for another.
         The only time we can fail the call and not bother hunting is
         if sng_cc_resource_check fails.
         Took out configuration retry as the config code is now
         fixed in sng_ss7 library. Transaction id fix.

Unit Tested:

NSG UP -- start full load
kill NSG
NSG UP again on full load
make sure it comes up fine.

         before hanging up the freetdm channel by force
         seems to have a memory leak.  I have increased the timeout
         to 30sec and made the print statement WARNING level.

Set the 3000ms warning to NOTICE not CRIT

Where FS does not hangup the channel with in 3sec.
Without this fix, it was possible that 2 FS sessions
use the single span/chan freetdm session.
Merged the feature from git master of freetdm

Its possible to timeout on ISUP ckt config in scenarios
of huge load.

switch-core: changed the exit status when modules fail to load to 65 (EX_DATAERR), init scripts must
             be updated to handle 65 instead of 1 to detect module loading errors
