dirstatemap: create `_dirs_incr/_dirs_decr` methods on the common class
The Rust wrapper does not need them. However having a default, no-op,
implementation will help use to write code used by both implementation.

Set up a repo
$ cat <<EOF >> $HGRCPATH
> [ui]
> interactive = true
> [extensions]
> record =
> EOF
$ hg init a
$ cd a
Record help
$ hg record -h
hg record [OPTION]... [FILE]...
interactively select changes to commit
If a list of files is omitted, all changes reported by 'hg status' will be
candidates for recording.
See 'hg help dates' for a list of formats valid for -d/--date.
If using the text interface (see 'hg help config'), you will be prompted
for whether to record changes to each modified file, and for files with
multiple changes, for each change to use. For each query, the following
responses are possible:
y - record this change
n - skip this change
e - edit this change manually
s - skip remaining changes to this file
f - record remaining changes to this file
d - done, skip remaining changes and files
a - record all changes to all remaining files
q - quit, recording no changes
? - display help
This command is not available when committing a merge.
(use 'hg help -e record' to show help for the record extension)
options ([+] can be repeated):
-A --addremove mark new/missing files as added/removed before
committing
--close-branch mark a branch head as closed
--amend amend the parent of the working directory
-s --secret use the secret phase for committing
-e --edit invoke editor on commit messages
-I --include PATTERN [+] include names matching the given patterns
-X --exclude PATTERN [+] exclude names matching the given patterns
-m --message TEXT use text as commit message
-l --logfile FILE read commit message from file
-d --date DATE record the specified date as commit date
-u --user USER record the specified user as committer
-S --subrepos recurse into subrepositories
-w --ignore-all-space ignore white space when comparing lines
-b --ignore-space-change ignore changes in the amount of white space
-B --ignore-blank-lines ignore changes whose lines are all blank
-Z --ignore-space-at-eol ignore changes in whitespace at EOL
(some details hidden, use --verbose to show complete help)
