            we dont want to optimize out symbols for debugging

         - glare
         - cgb/cgu range bug
         - inhibit/uninhibit

         The code was improperly using peer_data as an indicator that the sigbridge
         ss7 mode was enabled. The channel flag FTDM_CHANNEL_NATIVE_SIGBRDIGE should
         be used instead

freetdm: Fix improper logging statement when doing native ss7 bridge (peer_chan was set to the SIP leg)

freetdm: Add support to set/receive location and original call number SS7 elements through variables (including SIP X headers)

         - The outgoing tdm leg should not move to UP until
           after the IAM is sent at the end of the function
         - The UP state should be processed immediately otherwise
           the state processor is not run due to the way the main
           ss7 processing loop currently works

         for native bridging that caused infinite SUSPEND state executions
         due to peer member not being cleared at the end of the call

         - The queue size has been bumped again, long calls could potentially require more elements (multiple resume/suspend)
         - The queue is only used when there is a call active

           disable t6 finished.

         - 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
