rust-dirstatemap: add `NonNormalEntries` class
This fix introduces the same encapsulation as the `copymap`. There is no easy
way of doing this any better for now.

Pretty brutal regression!

rust-dirstatemap: cache non normal and other parent set
Performance of `hg update` was significantly worse since the introduction of
the Rust `dirstatemap`. This regression was noticed by Valentin Gatien-Baron
when working on a large repository, as it goes unnoticed for smaller
repositories like Mercurial itself.
This fix introduces the same getter/setter mechanism at `hg-core` level as
for `set/get_dirs`.
While this technique is, as previously discussed, quite suboptimal, it fixes an
important enough problem. Refactoring `hg-core` to use the typestate
pattern could be a good approach to improving code quality in a future patch.

chgserver: spawn new process if schemes change
The schemes extension updates hg.schemes table. It's technically possible
for hg.repository() to look for e.g. ui.schemes instead of depending on
module-local table, but I don't think the change would make much sense
since [schemes] is usually specified in ~/.hgrc and thus it can be considered
static data.

tests: accept new bzr message about switching branches
The new version apparently prints "Switched to branch at " instead of
"Switched to branch: ".

nodemap: keep track of the docket for loaded data
To perform incremental update of the on disk data, we need to keep tracks of
some aspect of that data.

nodemap: introduce an explicit class/object for the docket
We are about to add more information to this docket, having a clear location to

nodemap: keep track of the ondisk id of nodemap blocks

nodemap: provide the on disk data to indexes who support it
Time to start defining the API and prepare the rust index support. We provide
a method to do so. We use a distinct method instead of passing them in the
constructor because we will need this method anyway later (to refresh the mmap
once we update the data on disk).
