Improved Q.921/Q.931 debug output.
* Debug output for a sent Q.931 message in TE PTMP now uses the best available TEI number instead of always using 127. It could still be wrong if layer 2 does not have a TEI assigned. * Q.921 debug output is grouped better so a decoded message is not split by a blank line. * The Q.921 state is also decoded to a name. git-svn-id: https://origsvn.digium.com/svn/libpri/branches/1.4@1848 2fbb986a-6c06-0410-b554-c9c1f0a7f128
