delta: add sidedata field to revision delta
When emitting revision delta, we need to also emit the sidedata information just
added in the revlogv2 format if appropriate.

changegroup: add v4 changegroup for revlog v2 exchange
This change only adds the required infrastructure for the new changegroup format
and does not do any actual exchange. This will be done in the next patches.

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.
