Summary:                    [patch] New option setvarout which sets channel
variable for outbound channels to a peer
Description: 
The setvar option in sip.conf sets channel variables for inbound channels
(calls from a peer to *), but not for outbound channels (calls to a peer).
This patch adds support for a new option "setvarout" which adds that
capability.

Usecase:
The automon feature writes the recording to a file which contains the
channel name. It is currently not possible to reliably parse the name of
the peer from the channel. Setting the channel variable
TOUCH_MONITOR_PREFIX before executing the Dial(...,10,wW) app does not
work, because you cannot discriminate whether the caller or the callee hit
the record button. Using setvarout it is possible to have a easily parsable
automon file, by setting the TOUCH_MONITOR_PREFIX to the name of the peer
for inbound and outbound channels.

---------------------------------------------------------------------- 
As far as I can remember, you can't solve the use case with a 'Set' in the
dialplan, because you need different values for TOUCH_MONITOR_PREFIX in the
two legs of the call. Otherwise you cannot differentiate a recording which
was initiated by the caller from a recoding initiated by the callee. A
differentiation is useful if you e-mail the recordings.

Still confusing, or did that clear it up?
