dialplan: fix usage of avps in replacement expression

- clone the replacement expression to shared memory before parsing it in
  order to have variables names available at runtime
- most of variables should be safe to use now in replacement
  expressions, including avps with string name. This fixes FS#153
  reported by Andrew Pogrebennyk
- variables with dynamic name have no easy way to clone at this moment,
  thus avoid using them directly. Use instead avps or script vars
  ($var(...)), copying the value from initial variable to it. Variables
  pointing to sip message attributes are safe to use.
