CEL is the new system for logging channel events.  This was inspired after
facing many problems trying to represent what is possible to happen to a call
in Asterisk using CDR records.  For more information on CEL, see the built in
HTML or PDF documentation generated from the files in doc/tex/.

Many thanks to Steve Murphy (murf) and Brian Degenhardt (bmd) for their hard
work developing this code.  Also, thanks to Matt Nicholson (mnicholson) and
Sean Bright (seanbright) for their assistance in the final push to get this
code ready for Asterisk trunk.

Also change the default casing of the string contants to lowercase.  This really
just saves us from have to lowercase them later when displaying them.

This merge splits the PRI/BRI signaling logic out of chan_dahdi.c into
sig_pri.c. Functionality in theory should not change (mostly). A few trivial
changes were made in sig_analog with verbose messages and commenting.

  Resolve a crash related to a T.38 reinvite race condition.
  
  This change resolves a crash observed locally during some T.38 testing.
  A call was set up using a call file, and when the T.38 reinvite came in,
  the channel state was still AST_STATE_DOWN.  The reason is explained by
  a comment in the code that previously lived in the handling of
  AST_STATE_RINGING.  This change modifies the logic to handle the same
  race condition for any channel state that is not UP.

Also change the preferred configuration option from 'hostname' (which was
misleading because it didn't actually treat the value as a hostname) to
'connection' and added some verbage explaining that the user would need to
refer to their freetds.conf file for those settings.  'hostname' was kept
as a backwards compatible configuration parameter.

If the outgoing_colp parameter is set to not send COLP information, then
it does not make sense to send redirecting or transfer messages announcing
new COLP information that is blocked.  The service provider may supply the
listed number for that line when it passes the messages to the next hop.
Why tell the switch that these events happened when the information is
otherwise suppressed?

Also blocked the number of previous redirects that may have occurred to
calls going out the port when outgoing_colp is 2.

  Fix a situation in which Asterisk would not stop retransmitting 487s.
  
  If a CANCEL were received by Asterisk, we would send a 487 in response
  to the original INVITE and a 200 OK for the CANCEL. If there were a network
  hiccup which caused the 200 OK and the 487 to be lost, then the UA communicating
  with Asterisk may try to retransmit its CANCEL. Asterisk's response to this used
  to be to try sending another 487 to the canceled INVITE and another 200 OK to the
  CANCEL.
  
  The problem here is that the originally-sent 487 was sent "reliably" meaning that
  it will be retransmitted until it is received properly. So when we receive the second
  CANCEL it is likely that the first batch of 487s we sent is still going strong and
  reaches the UA. The result was that the second set of 487s would be retransmitted
  constantly until the maximum number of retries had been reached.
  
  The fix for this is that if we receive a second CANCEL for an INVITE, then we cancel
  the retransmission of the first set of 487s and start a second set. This causes the
  dialog to be terminated reasonably.
