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.

Checking how hg behaves when one side of a pull/push doesn't support some capability (because it's running an older hg version, usually). $ hg init repo1 $ cd repo1 $ echo a > a; hg add -q a; hg commit -q -m a $ hg bookmark a $ hg clone -q . ../repo2 $ cd ../repo2 $ touch $TESTTMP/disable-lookup.py $ disable_cap() { > rm -f $TESTTMP/disable-lookup.pyc # pyc caching is buggy > cat <<EOF > $TESTTMP/disable-lookup.py > from mercurial import extensions, wireprotov1server > def wcapabilities(orig, *args, **kwargs): > cap = orig(*args, **kwargs) > cap.remove(b'$1') > return cap > extensions.wrapfunction(wireprotov1server, '_capabilities', wcapabilities) > EOF > } $ cat >> ../repo1/.hg/hgrc <<EOF > [extensions] > disable-lookup = $TESTTMP/disable-lookup.py > EOF $ cat >> .hg/hgrc <<EOF > [ui] > ssh = "$PYTHON" "$TESTDIR/dummyssh" > EOF $ hg pull ssh://user@dummy/repo1 -r tip -B a pulling from ssh://user@dummy/repo1 no changes found $ disable_cap lookup $ hg pull ssh://user@dummy/repo1 -r tip -B a pulling from ssh://user@dummy/repo1 abort: other repository doesn't support revision lookup, so a rev cannot be specified.
