rust-index: using `hg::index::Index` in `hg-cpython::dagops`
Hooking `headrevs` to the Rust index is straightforward as long as
we go the `PySharedRef` way. Direct attempts of obtaining a reference
to the inner `hg::index::Index` fail for lifetime reasons: the reference
is bound to the GIL, yet the `as_set` local variable is considered to
be static (the borrow checker clearly does not realize or care that this
set only stores `Revision` values).
In `rank()`, the chosen solution is the simplest as far as `hg-cpython` is
concerned, but it has the defect of removing an implementation
that would be easily adaptable if the core index did implement `RankedGraph`
(returning the same error as long as only `REVLOGV1` is supported), but that
would introduce a direct dependency of `hg-core` on the ``vcsgraph` crate.

There are some web servers in the wild that can serve static files with an
incorrect encoding (e.g. https://bz.mercurial-scm.org/show_bug.cgi?id=6559).
One way to prevent any issues is to not use any non-ASCII characters, e.g.
URL-encoding them or using HTML entities.
