Redmine Bug#1966
IAM ->
<-REL
<-ACM
<-ANM

ACM sets the reset flag
ANM sets the group reset flag
when both reset flags are set we got into infinite loop

         relay - configuring circuits only when resume is recieved.
	 master - configuring relay after all the others are configured.

  make[6]: *** [ftmod_sangoma_ss7_la-ftmod_sangoma_ss7_handle.lo] Error 1

         error was caused by printing string value to integer

         cpg_on_progress_media is default to TRUE if not xml option exists.
         transparent_iam_max_size added to ccspan.  Gloal value is used
         if transparent_iam_max_size is not in ccSpan.

         Fixes in hw alarm - no need to set hw unblock if hw block did not execute yet.
         Minor bug fixes

         Added more documentation in main

         Fixed hw alarm handling: physical ids were not used which caused alarms
         read wrong.
         Tested sip hold
         Group blocks/unblock
         Group reset
         Link down-> block -> unblock
         FS start with link down then link up
         FS start with link up, take link down and up -> make incoming call

         Only send out an unblock if block was sent from hw alarm and there are no
         maintenance blocks pending.

         * FreeTDM modules using the old FTDM_SPAN_STATE_CHANGE flag should be updated   *
         * until then, they are still vulnerable to deadlock situations                  *
         * Modules pending update: (ftmod_analog, ftmod_libpri, ftmod_isdn)              *
