Summary:                    [patch] export the SIP peer username of the
transferer
Description: 
Hi!

When a blind transfer is initiated from a SIP, often the name of the
transferer is needed (e.g. billing, applying restrictions ...). Currently
there is a variable called SIPTRANSFER_REFERER which contains the value of
the Refered-By header - but this variable is not trustworthy, as the SIP
client can put anything into this variable.

Attached patch adds the variables SIPTRANSFERER_PEERNAME and
SIPTRANSFERER_USERNAME which contain the respective SIP username (peer or
user)

---------------------------------------------------------------------- 
The TRANSFER_CONTEXT is entered with the channel of the transferee. Thus I
suspected that ${SIPCHANINFO(peername)} is the transferee peer, not the
transferer. But I have not tested, I will try tomorrow.

In case I am right, then also a function could not help as the information
is lost, only the ->referedby member is copied but this one is useless.
