As an Asterisk manager, I might need some variables for each and every call started by the manager account - like a windows pop up client. In my deployments, this has been missing - much like context limitation, which is another review.

I'm fine with the concept, and I agree with Olle's assertion in one of 
the ReviewBoard comments that usage of this feature will be by Asterisk 
admins who are trying to ensure that all channels created by a specific 
AMI user have particular channel variables set with specific values. 
This is a policy decision, it's not for setting 'defaults' that the user 
can override/remove.

I only have two comments on the work as it has been proposed:

* The name 'setvar' is not specific enough, because manager.conf defines 
'manager users', not devices that create channels. 'channelvar' would be 

* We need testing to ensure that the addition of these variables to the 
list provided in the AMI Originate action (if any) properly results in 
the values from the manager.conf file taking precedence over the ones 
from the Originate action. The code claims this is the case, but we need 
to be very sure that it is in fact the case, and the comment in th code 
needs to be worded very strongly to ensure that people modifying the 
code in the future understand why it is done this way.
