test: pin the number of CPU for issue4074 tests
On machine with an hundreds of CPUs, the "user" CPU time reported can be
inflated by the status steps. Since the test especially focus on the diff
computation, we restrict the number of CPU to avoid potential issues.

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.
`hg up -r null && time HGRCPATH= HGMODULEPOLICY=rust+c hg up tip` on Mozilla
Central, (not super recent, but it doesn't matter):
Before: 7:44,08 total
After: 1:03,23 total
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
stock them in memory will help.

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).
