Nguyễn Thái Ngọc Duy b640313110 dir.c: fix missing dir invalidation in untracked code
Let's start with how create a new directory cache after the last one
becomes invalid (e.g. because its dir mtime has changed...). In
open_cached_dir():

1. We start out with valid_cached_dir() returning false, which should
   call invalidate_directory() to put a directory state back to
   initial state, no untracked entries (untracked_nr zero), no sub
   directory traversal (dirs[].recurse zero).

2. Since the cache cannot be used, we go the slow path opendir() and
   go through items one by one via readdir(). All the directories on
   disk will be added back to the cache (if not already exist in
   dirs[]) and its flag "recurse" gets changed to one to note that
   it's part of the cached dir travesal next time.

3. By the time we reach close_cached_dir() we should have a good
   subdir list in dirs[]. Those with "recurse" flag set are the ones
   present in the on-disk directory. The directory is now marked
   "valid".

Next time read_directory() is called, since the directory is marked
valid, it will skip readdir(), go fast path and traverse through
dirs[] array instead.

Steps one and two need some tight cooperation. If a subdir is removed,
readdir() will not find it and of course we cannot examine/invalidate
it. To make sure removed directories on disk are gone from the cache,
step one must make sure recurse flag of all subdirs are zero.

But that's not true. If "valid" flag is already false, there is a
chance we go straight to the end of valid_cached_dir() without calling
invalidate_directory(). Or we fail to meet the "if (untracked-valid)"
condition and skip over the invalidate_directory().

After step 3, we mark the cache valid. Any stale subdir with incorrect
recurse flag becomes a real subdir next time we traverse the directory
using dirs[] array.

We could avoid this by making sure invalidate_directory() is always
called (therefore dirs[].recurse cleared) at the beginning of
open_cached_dir(). Which is what this patch does.

As to how we get into this situation, the key in the test is this
command

    git checkout master

where "one/file" is replaced with "one" in the index. This index
update triggers untracked_cache_invalidate_path(), which clears valid
flag of the root directory while keeping "recurse" flag on the subdir
"one" on. On the next git-status, we go through steps 1-3 above and
save an incorrect cache on disk. The second git-status blindly follows
the bad cache data and shows the problem.

This is arguably because of a bad design where "recurse" flag plays
double roles: whether a directory should be saved on disk, and whether
it is part of a directory traversal.

We need to keep recurse flag set at "checkout master" because of the
first role: we need to keep subdir caches (dir "two" for example has
not been touched at all, no reason to throw its cache away).

As long as we make sure to ignore/reset "recurse" flag at the
beginning of a directory traversal, we're good. But maybe eventually
we should separate these two roles.

# On some filesystems (e.g. FreeBSD's ext2 and ufs) directory mtime
# is updated lazily after contents in the directory changes, which
# forces the untracked cache code to take the slow path. A test
# that wants to make sure that the fast path works correctly should
# call this helper to make mtime of the containing directory in sync
# with the reality before checking the fast path behaviour.
