Summary:                    [patch] Setting up a HANGUPCAUSETEXT variable for
SIP channel
Description: 
I found that sometimes it's needed to have the exactly "SIP disconnect
code" from the other end. HANGUPCAUSE could not be enough as it's mapping
different SIP codes to the same number.

After talking about it in -dev mailing list:
http://lists.digium.com/pipermail/asterisk-dev/2008-July/034004.html

Some people was interested and attached there is a initial patch to
implement it.

Note: there is a problem with a Dial to multiple channels: same problem
than HANGUPCAUSE. A good solution, as talked here:

http://lists.digium.com/pipermail/asterisk-dev/2008-July/034020.html

is to have a hash/function handling all disconnect reasons. In this status
the classic HANGUPCAUSE and also HANGUPCAUSETEXT don't handle it.

In my tests the patch has been working fine. If you see any problem or
patch should be done in a different way, I'm open to work on it.

Okay, new solution.  This creates a universal accessor method back to the
creating channel, through a dialplan function called MASTER_CHANNEL(). 
This will allow dialplan users in macros to also pass back values to the
master channel.
