This is retry of #1419.
I added flush_fscache macro to flush cached stats after disk writing
with tests for regression reported in #1438 and #1442.
git checkout checks each file path in sorted order, so cache flushing does not
make performance worse unless we have large number of modified files in
a directory containing many files.
Using chromium repository, I tested `git checkout .` performance when I
delete 10 files in different directories.

Teach "add" to use preload-index and fscache features
to improve performance on very large repositories.
During an "add", a call is made to run_diff_files()
which calls check_remove() for each index-entry. This
calls lstat(). On Windows, the fscache code intercepts
the lstat() calls and builds a private cache using the
FindFirst/FindNext routines, which are much faster.
Somewhat independent of this, is the preload-index code
which distributes some of the start-up costs across
multiple threads.
We need to keep the call to read_cache() before parsing the
pathspecs (and hence cannot use the pathspecs to limit any preload)
because parse_pathspec() is using the index to determine whether a
pathspec is, in fact, in a submodule. If we would not read the index
first, parse_pathspec() would not error out on a path that is inside
a submodule, and t7400-submodule-basic.sh would fail with
not ok 47 - do not add files from a submodule
We still want the nice preload performance boost, though, so we simply
call read_cache_preload(&pathspecs) after parsing the pathspecs.

Windows' equivalent to "bind mounts", NTFS junction points, can be
unlinked without affecting the mount target. This is clearly what users
expect to happen when they call `git clean -dfx` in a worktree that
contains NTFS junction points: the junction should be removed, and the
target directory of said junction should be left alone (unless it is
inside the worktree).

It seems to be not exactly rare on Windows to install NTFS junction
points (the equivalent of "bind mounts" on Linux/Unix) in worktrees,
e.g. to map some development tools into a subdirectory.
In such a scenario, it is pretty horrible if `git clean -dfx` traverses
into the mapped directory and starts to "clean up".
Let's just not do that. Let's make sure before we traverse into a
directory that it is not a mount point (or junction).

"git show-branch --no-topo-order" behaved exactly the same way as
"git show-branch --topo-order" did, which was nonsense. This was
because we choose between topo- and date- by setting a variable to
either REV_SORT_IN_GRAPH_ORDER or REV_SORT_BY_COMMIT_DATE with
OPT_SET_INT() and REV_SORT_IN_GRAPH_ORDER happens to be 0. The
OPT_SET_INT() macro assigns 0 to the target variable in respose to
the negated form of its option.
"--no-date-order" by luck behaves identically to "--topo-order"
exactly for the same reason, and it sort-of makes sense right now,
but the "sort-of makes sense" will quickly break down once we add a
third way to sort. Not-A may be B when there are only two choices
between A and B, but once your choices become among A, B, and C,
not-A does not mean B.
Just mark these two ordering options to reject negation, and add a
test, which was missing. "git show-branch --no-reflog" is also
unnegatable, so throw in a test for that while we are at it.

"git show-branch --no-sparse" behaved exactly the same way as "git

because it used a variable "dense" initialized to 1 by default to
give "non sparse" behaviour, and OPT_SET_INT() to set the varilable
to 0 in response to the "--sparse" option. Unfortunately,
OPT_SET_INT() sets 0 to the given variable when the option is
negated.
Flip the polarity of the variable "dense" by renaming it to "sparse"
and initializing it to 0, and have OPT_SET_INT() set the variable to
1 when "--sparse" is given. This way, "--no-sparse" would set 0 to
the variable and would give us the "dense" behaviour.

There are a few callback functions which are used with the fsck code,
but it's natural that not all callbacks need all parameters. For
reporting, even something as obvious as "the oid of the object which had
a problem" is not always used, as some callers are only checking a
single object in the first place. And for both reporting and walking,
things like void data pointers and the fsck_options aren't always
necessary.

In a narrow but common case, the user is the only author of a branch and
doesn't mind overwriting the corresponding branch on the remote. This
workflow is especially common on GitHub, GitLab, and Gerrit, which keep
a permanent record of every version of a branch that is pushed while a
pull request is open for that branch. On those platforms, force-pushing
is encouraged and is analogous to emailing a new version of a patchset.
When giving advice about divergent branches, tell the user about
`git pull`, but don't unconditionally instruct the user to do it. A less
prescriptive message will help prevent users from thinking that they are
required to create an integrated history instead of simply replacing the
previous history. Also, don't put `git pull` in an awkward
parenthetical, because `git pull` can always be used to reconcile
branches and is the normal way to do so.
Due to the difficulty of knowing which command for force-pushing is best
suited to the user's situation, no specific advice is given about
force-pushing. Instead, the user is directed to the Git documentation to
read about possible ways forward that do not involve integration.
