  cfgutils: Add support for dynamic shared vars ($shv)

OpenSIPS script developers now have the ability to use dynamic names for
the $shv variables (e.g. "$shv($avp(customer_id))"), rather than be
constrained to work with the statically-named $shv variables defined
throughout the script.

Moreover, shared variables may now be dynamically created and read via
the well-known MI commands: "shv_set" and "shv_get".

Closes #2140
