Summary:                    [patch] Feature to write variables to existing
channels other than your own (func chanvar)
Description: 
Many, many times I ran into a dialplan issue where I wanted to set a
variable in the called channel whilst the dialplan was running in the
calling channel.
To my frustration an application like ImportVar() existed but something
like ExportVar() did not.

After bumping into the issue a bit too often I deciced to write it myself
:-)
It probably took me less time writing the patch than it took finding out
ways to realize this feature with the current set of applications &
functions :-(

Anyway...
I started out writing the patch for 1.4.17 and called it 'ExportVar'.
But after finding out it was deprecated in the svn-trunk and talking to
Digium (Qwell) about it,
I decided to create a new logical function in func_logic called
'CHANVAR'.
This feature includes read & write making function 'ImportVar' & 'IMPORT'
both obsolete.
Since function 'IMPORT' is only in teh svn-trunk perhaps it should be
removed or deprecated if this patch gets submitted. 

This is how the new feature works;

To read a variable from another channel;
- Set(CHANVAR(channel,variable)=value)

To write a variable to another channel;
- Set(varname=${CHANVAR(channel,variable)})


PS:
For everyone that wants to add this feature (themselves) to Asterisk
1.4.17 a path to backport to 1.4.17 is also uploaded.
