Add REPLACE & PASSTHRU functions, overhaul of func_strings, fix API docs for the ast_get_encoded_* functions.

Browse Source 
* Add REPLACE function, which searches a given variable for a set of
   characters and replaces each with a given character.
 * Add PASSTHRU function, which passes a literal string back, like a NoOp for
   functions.  Intent is to be able to specify a literal string to another
   function that takes a variable name as an argument.
 * Let the array manipulation functions work with dialplan functions, in
   addition to variables.  This allows the array manipulation functions to
   modify ASTDB and ODBC backends, assuming the func_odbc configuration has
   both read and write functions.
