Summary
-------

Adds a dialplan function named EXPORT that lets you set channel variables on other channels. It is based on IMPORT. Originally it was ExportVar based on ImportVar, but while porting to 1.8 I noticed ImportVar was depreciated.

You can set either a simple variable or a function.
Example dialplan that sets a function (you would 'console dial XXXX at test-local'):

[test]
exten => _X.,1,NoOp()
exten => _X.,n,Set(EXPORT(${TEST},CDR(userfield))=blah)
exten => _X.,n,Dial(SIP/sometrunk/${EXTEN})

[test-local]
exten => _X.,1,NoOp()
exten => _X.,n,Set(__TEST=${CHANNEL})
exten => _X.,n,Dial(Local/${EXTEN}@test/n)

Testing
-------

I tested it by dialing on the console, using variations of the simple dialplan above, testing setting both variables and functions, and using 'core show channel' to verify everything was set correctly.
