Summary:                    [patch] Reason header support
Description: 
Cisco GWs use this header, however it is only a rfc draft.

draft-jesske-sipping-etsi-ngn-reason-03.txt

just set:
use_q850_reason=yes 
in sip peer/user configuration and chan_sip.c will insert
Reason: Q.850;cause=17
header.
If the peer send Reason header will be used instead of
hangup_sip2cause().

---------------------------------------------------------------------- 
I implemented my idea (above) on chan_sip.c and now it processes Q.850
reason headers for BYE _REQUESTS_. I don't know if this is on the scope of
this bug and it belongs here.

Note: my patch modifies '&owner->hangupcause' successfully but because the
channel expires upon BYE, the HANGUPCAUSE channel variable is not available
in the 'h' extension dialplan.
I changed it further to save the value in a global variable with
'builtin_pbx_setvar_helper(NULL,hangupcause<number>,hangupcausevalue)', but
that's kind of unelegant. If anyone is interested in this patch, I'll post
it.
