cindex: simplify some internal data structures

We'll rely more on local-ized `our' globals rather than
hashref fields.  The former is more resistant to typos
and can be checked at compile-time earlier via `perl -c'.

The {-internal} field is also renamed to {-cidx_internal}
in case to reduce confusion within a large code base.
