revlogv2: don't assume that the sidedata of the last rev is right after data
We are going to be rewriting sidedata soon, it's going to be appended to the
revlog data file, meaning that the data and the sidedata might not be
contiguous.

sidedata: move to new sidedata storage in revlogv2
The current (experimental) sidedata system uses flagprocessors to signify the
presence and store/retrieve sidedata from the raw revlog data. This proved to be
quite fragile from an exchange perspective and a lot more complex than simply
having a dedicated space in the new revlog format.
This change does not handle exchange (ironically), so the test for amend - that
uses a bundle - is broken. This functionality is split into the next patches.

cext: add support for revlogv2
This enables the C code to retrieve/create entries in the revlog v2 format.
This is mainly a matter of taking into account the additional slots for
sidedata, etc.

format: remove sidedata format variant
This format variant can only exist when also using revlog v2, so it's useless
now.

revlogv2: allow upgrading to v2
Revlogv2 implies sidedata.
Right now sidedata is not really used in production, and Revlogv2 will be used
for the first production-ready version of sidedata support.

revlog: introduce v2 format
As documented in [1], this is still tentative and could be subject to change,
but we need to lay down the foundations in order to work on the next abstraction
layers.

rebase: inline simple function for finding obsolete subset of commits
`_filterobsoleterevs()` is just one line long. It was introduced in
2d294dada4f8 (rebase: small refactoring to allow better extensibility
from extensions, 2016-01-14), for use by the "inhibit" extension. That
extension was removed from the evolve repo in 87e87881059d (compat:
drop the inhibit hacky extension, 2017-10-24).
