the 'data' field in action tags may now refer to variables and api functions
to be expanded at runtime.
Syntax:
$varname
${varname}
&func_name(func args)
Exception:
variables that are numeric are still expanded at dialplan compile time based on the regex eg $1 $2 etc
Example:
<extension name="1000">
<condition field="destination_number" expression="^(1000)$">
<action appplication="my_route_app" data="$1"/>
<action appplication="bridge" data="$destination"/>
</condition>
</extension>
Here the $1 is ecaluated before the call begins setting it to 1000 based on the regex ^(1000)$
$destination is evaluated on the fly in execution once the my_route_app has run and has had a
chance to set the variable 'destination' to the correct value.
