dirstate-map: factor out the change to _dirs and _alldirs on dropping
This logic is complicated enough to deserves its own function. So it now does.
This will make it easier to reuse that logic in later changeset.

dirstate-v2: Separate iterators for dirfoldmap and debugdirstate
`dirstatemap.dirfoldmap` was recently changed to re-use a Rust iterator
that was added for the `hg debugdirstate` command.
That iterator was based on all nodes in the tree dirstate without an entry
only existing to hold child nodes, and therefore being directories.
However to optimize status further we may want to store additional nodes
for unknown or ignored files and directories. At that point the two users
of this iterator will want different things, so let’s make two iterators
instead.
See doc-comments in `dispatch.rs`.

dirstate-v2: Move fixed-size tree metadata into the docket file
Before this changeset, the dirstate-v2 data file contained not only nodes
and paths that may be reused when appending to an existing file,
but also some fixed-size metadata that applies to the entire tree
and was added at the end of the data file for every append.
This moves that metadata into the docket file, so that repeated "append"
operations without meaningful changes don’t actually need to grow any file.

dirstate-v2: Add heuristic for when to create a new data file
… instead of appending to the existing one. This is based on keeping track
of how much of the existing data is not used anymore.

dirstate-v2: Reuse existing paths when appending to a data file
When writing a dirstate in v2 format by appending to an existing data file,
filenames / paths that are borrowed from the previous on-disk representation
can be reused.

dirstate-v2: Reuse existing nodes when appending to a data file
When writing a dirstate in v2 format by appending to an existing data file,
nodes that are still "unparsed" from the previous on-disk representation
have been unchanged and can therefore be reused.
This makes the new data point to previously-existing data for tree nodes.
