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.
