ui: fix crash in `hg paths` when pulled-delta-reuse-policy is in use
The crash is a result of [value] being an int, but being used
as a bytestring.

re2: fix reporting of availability in `hg debuginstall`
We add and use an official API to check is re2 is available. This prevent the
bug previously in place were debuginstall was considering confusing `None`
(i.e. non-initialized) and `False` (i.e. unavailable).

re: make _checkre2 a static method
There is no need to it to be a method, so we make it at least a static method to
make it easier to call.

re2: exit `_checkre2` early if calling it is useless
If we already know if re2 is supported there is no need to run the check again.
Stricly speaking we don't call it twice, but this seems a simple enough
safeguard to include in this series.

test-dirstate-version-fallback: future-proof the test for a different default
Dirstate-v2 will become the default at some point, which would cause this
test to fail. Let's save someone else the headache later.

revlog: avoid possible collision between directory and temporary index
Since 6.4, we create a temporary index file to write the split data without
overwriting the inline version too early. However, the store encoding does not
prevent these new `.i.s` file to collide with a directory with the same name.
While the odds for such a collision to happens are fairly low, the collision
would prevent Mercurial from working.
The store encoding have a mitigation solution in place to prevent such
collisions from happening for `.i` and `.d` files, but not for other extensions.
We cannot update this encoding scheme to solve the issue since it would diverge
from older version of Mercurial.
Instead, we create an alternative directory tree dedicated to such files.
The use of the `.i` extension combined with store encoding will prevent
collisions there.

rust-dirstate: fall back to v1 if reading v2 failed
This will help us not fail when a v1 dirstate is present on disk while a v2
was expected (which could happen with a racy/interrupted upgrade).

rust-dirstate: rename `has_dirstate_v2` to `use_dirstate_v2`
It is closer to the right semantics. I added a docstring to better explain

of finding the "wrong" version of the dirstate on disk.

delta-find: fix pulled-delta-reuse-policy=forced behavior
The code that select delta still has too many oportunity to discard the delta
is has been forcibly asked to reuse. However is is fairly easy to use a
dedicated fastpath for this case. So we do so.
Cleaning other code that tries to enforce that policy will be done on default.
