revlog: deal with special "postfix" explicitely
revlog usually use a straight forward '.i' and '.d' naming except for two cases
"in-transaction" changelog, and censoring. Our goal is to let the revlog code
deal with the internal of the file naming itself. To do so, we need to start
dealing with these postfix explicitly.

revlog: split the option initialisation in its own method
The part of the code is huge, keeping it separated will keep the `_loadindex`
method simpler and help keeping logic well insulated.

revlog: always "append" full size tuple
Same reasoning as the previous patch.

revlog: make the index always return the same tuple
It is simpler to manage the diferrence in on disk format in the internal index
code itself and lets the rest of the code always handle the same object.
This will become even more important when the data we store will be entirely
different (for example the changelog does not need the "linkrev" field.
We start with item reading, we will deal with item writing in the next
changesets.

revlog: introduce an explicit `format_version` member in the index struct
This will allow for cleaner check than assuming each version has a different
size. Unsurprisingly I am planning to use this to introduce more format variant.

revlog: rename `hdrsize` to `entry_size` in the C code
This is the size of and index entry, so lets make it clearer.
