Summary:                    [patch] Fetching SIP headers from BYE sent by callee
Description: 
We have simple situation:

exten => _X.,1,DIAL(SIP/mypeer/${EXTEN})
exten => h,1,AGI(billing)

There is no way to get headers from BYE message sent by callee. But a lot
of harware provide usefull headers in BYE message, for example Linksys
provide header P-RTP-Stat which contain packet counters, jitter, delay
etc..:

P-RTP-Stat:
PS=256,OS=40960,PR=244,OR=39040,PL=29920,JI=5,LA=0,DU=4,EN=G711a,DE=G711a

Cisco provides another usefull header 'Reason' which contain ISDN hangup
cause code:

Reason: Q.850;cause=16


This patch allows user to fetch any header from BYE sent by callee. It
introduces special variable SIPREMOTEBYEHEADER. This variable should
contain 2 coma separated values. 1st value - a sip header that should be
fetched, 2nd value - name of variable to put sip header in.

So to fetch Header 'Reason' sent by cisco, you simply need to set
variable:

exten => _X.,1,SET(SIPREMOTEBYEHEADER=Reason,MYVAR)
exten => _X.,2,DIAL(SIP/mypeer/${EXTEN})
exten => h,1,AGI(billing)

Right after mypeer sends a BYE, you will have variable MYVAR defined on
your channel.

Patches against branch 1.6.0 and trunk provided.
