revlog: use `format_version` to dispatch different version in index_get
This is semantically more correct.

revlog: add a "data compression mode" entry in the index tuple
That will make it possible to keep track of compression information in the
revlog index, opening the way to more efficient revision restoration (in native
code, but the python usage is already defeating performance work).
We start with adding a new entry to the index tuple, using a value matching the
current behavior. We will introduce storage and other value in later changesets.

This is not a proper index tuple.

revlog: create a create `null_item` attribute for V0
This value is currently wrong, but at least it is now -obviously- wrong.

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.

revlog: simplify entry update logic in `rewrite_sidedata`
We don't need to rebuild the full entry. So lets just gather the data we need
to pass to `replace_sidedata_info`.
