revlog: improve documentation of the entry tuple

The code in revlog, and outside revlog directly use the index's entry tuple,
with direct integer indexing. This is a voluntary trade off to obtains better
performance from the  Python code at the expense of the developers sanity.

Let's at least have a clear and central documentation about what this tuple is
about.
