func_config: Add ability to retrieve specific occurrence of a variable

Browse Source 
I guess nobody uses templates with AST_CONFIG because today if you have a
context that inherits from a template and you call AST_CONFIG on the context,
you'll get the value from the template even if you've overridden it in the
context.  This is because AST_CONFIG only gets the first occurrence which is
always from the template.

This patch adds an optional 'index' parameter to AST_CONFIG which lets you
specify the exact occurrence to retrieve, or '-1' to retrieve the last.
The default behavior is the current behavior.
