revlog: add one more assert about state of thing when splitting This assert is currently happy, but it does not hurt to adds it to clarify expected state and catch potential error in the future.

add: don't attempt to add back removed files unless explicitly listed This fixes the bug demonstrated by the previous patch.

tests: show failure to `hg add -I` a dir->symlink transition

setup: try a non-pure version of the local Mercurial if the pure fails Things like `zstd` can make the pure version fails.

setup: make debug simpler by adding a `__repr__` to `hgcommand` This help when trying to debug this logic.

censor: fix things around inlining The temporary revlog cannot go through the inline → split process as this would break at transaction commit. (that might be fixable, but lets keep things simple for now). We introduce a cleaner way to enforce this as the previous one was broken in 6.6 On the way we remove multiple weird, fragile and broken overwrite of revlog attributes and we focus on passing the configuration across. We also had to update the test to actually create a non-inline revlog.

revlog: add a `may_inline` argument to revlog This allow for a clean skipping of the inline feature when needed, for example by censor.

revlog: allow explicit passing of config to revlog This will be useful to fix censor in a later changeset.

censor: show that the `not-inline` → `inline` test is broken The source revlog should not be inlined and it is…
