rust-index: use interior mutability in head revs and caches
For upcoming changes in `hg-cpython` switching to the `hg-core` index in
ancestors iterators, we will need to avoid excessive mutability, restricting
the use of mutable references on `hg::index::Index` to methods that actually
logically mutate it, whereas the maintenance of caches such as `head_revs`
clearly does not. We illustrate that immediately by switching to immutable
borrows in the corresponding methods of `hg-cpython::MixedIndex`
"""collection of simple hooks for common tasks (EXPERIMENTAL)
This extension provides a number of simple hooks to handle issues
commonly found in repositories with many contributors:
- email notification when changesets move from draft to public phase
- email notification when changesets are obsoleted
- enforcement of draft phase for all incoming changesets
- enforcement of a no-branch-merge policy
- enforcement of a no-multiple-heads policy
The implementation of the hooks is subject to change, e.g. whether to
implement them as individual hooks or merge them into the notify
extension as option. The functionality itself is planned to be supported
long-term.
