Summary:                    [patch] safe/limited Originate manager action
Description: 
The manager action of date allows someone with a "call" write permission to
run an arbitrary command with the Asterisk user (using e.g. the System
application). It also allows the originator to generate a call to just
about anywhere in the dialplan.

This patch is attempts to be a first step towards providing a safer
Originate action. It adds a new permission type, "safe_call". And then goes
to add a new meaning to the Originate action if the caller has only
"safe_call" write permissions but not "call" write permissions:

* The originator cannot use the "Application" form. It must originate a
cal to an extension.

* The Context set by the originaator is ignored, and replaced by the
context set for it in the managers.conf .

* A Local channel is not allowed, as it would allow using an arbitrary
context.

This still allows the originator to generate a call from an arbitrary
channel, which is probably not safe. But gets rid of most of the issues.

It is currently a proof of concept code - tested to build but not to run.

srt: arbitrary extension, not application.  Yes, which applications you can
execute should be restricted; that's obvious.  But extension?
