rust-cpython: using rustext.dagop.headrevs in revlog As with the previous oxidation series, revlog plays the role of the factory, either using its parents function, or passing the index. We include below results of revsetbenchmarks.py taken on the PyPy repository on those of contrib/all-revsets.tx that involve `heads()`. In most of the cases, this seems to be either neutral or an improvement. In the cases where it's actually a bit slower, we suspect that differences in `heads()` performance is actually burried in variance on the incoming revset (probably several orders of magnitude slower). The precheck for filtered revisions of parent changeset has a significative performance benefit, too.

## What is it?

     2

     3

This extension adds ability to save certain pushes to a remote blob store

     4

as bundles and to serve commits from remote blob store.

     5

The revisions are stored on disk or in everstore.

     6

The metadata are stored in sql or on disk.
