verify: use some intermediate variables instead of a multi-liner
This is shorter and easier to read as the indentation remains the same.

dirstate-v2: Drop parent directory cache when removing a dirstate node
The premise of the directory cache is that the dirstate contains child nodes
for every entry that `read_dir` would return. When removing nodes, that may
not be the case anymore so the cache should be invalidated.

dirstate-v2: Add --dirs to debugdirstate command
`hg debugdirstate --dirs` also shows information stored in the dirstate
(for `read_dir` caching) about directories.

dirstate-v2: Skip readdir in status based on directory mtime
When calling `read_dir` during `status` and the directory is found to be
eligible for caching (see code comments), write the directory’s mtime to the
dirstate. The presence of a directory mtime in the dirstate is meaningful
and indicates eligibility.
When an eligible directory mtime is found in the dirstate and `stat()` shows
that the mtime has not changed, `status` can skip calling `read_dir` again
and instead rely on the names of child nodes in the dirstate tree.
The `tempfile` crate is used to create a temporary file in order to use its
modification time as "current time" with the same truncation as other files
and directories would have in their own modification time.

dirstate-v2: Allow tree nodes without an entry to store a timestamp
Timestamps are stored on 96 bits:
* 64 bits for the signed number of seconds since the Unix epoch
* 32 bits for the nanoseconds in the `0 <= ns < 1_000_000_000` range
For now timestamps are not used or set yet.
