cygwin: Remove the Win32 l/stat() implementation

Commit adbc0b6b ("cygwin: Use native Win32 API for stat", 30-09-2008)
added a Win32 specific implementation of the stat functions. In order
to handle absolute paths, cygwin mount points and symbolic links, this
implementation may fall back on the standard cygwin l/stat() functions.
Also, the choice of cygwin or Win32 functions is made lazily (by the
first call(s) to l/stat) based on the state of some config variables.

Unfortunately, this "schizophrenic stat" implementation has been the
source of many problems ever since. For example, see commits 7faee6b8,
79748439, 452993c2, 085479e7, b8a97333, 924aaf3e, 05bab3ea and 0117c2f0.

In order to avoid further problems, such as the issue raised by the new
reference handling API, remove the Win32 l/stat() implementation.

builtin/rm.c: consolidate error reporting for removing submodules

We have two (not identical) copies of error reporting when
attempting to remove submodules that have their repositories
embedded within them.  Add a helper function so that we do not have
to repeat similar error messages with subtly different wording
without a good reason.

Noticed by Jiang Xin.

mv: move submodules together with their work trees

Currently the attempt to use "git mv" on a submodule errors out with:

  fatal: source directory is empty, source=<src>, destination=<dest>

The reason is that mv searches for the submodule with a trailing slash in
the index, which it doesn't find (because it is stored without a trailing
slash). As it doesn't find any index entries inside the submodule it
claims the directory would be empty even though it isn't.

Fix that by searching for the name without a trailing slash and continue
if it is a submodule. Then rename() will move the submodule work tree just
like it moves a file.

mv: move submodules using a gitfile

When moving a submodule which uses a gitfile to point to the git directory
stored in .git/modules/<name> of the superproject two changes must be made
to make the submodule work: the .git file and the core.worktree setting
must be adjusted to point from work tree to git directory and back.

Achieve that by remembering which submodule uses a gitfile by storing the
result of read_gitfile() of each submodule. If that is not NULL the new
function connect_work_tree_and_git_dir() is called after renaming the
submodule's work tree which updates the two settings to the new values.

Extend the man page to inform the user about that feature (and while at it
change the description to not talk about a script anymore, as mv is a
builtin for quite some time now).

functions to submodule.c. The first makes it possible for call sites to
see if the .gitmodules file did contain any unstaged modifications they
would accidentally stage in addition to those they intend to stage
themselves. The second function stages all modifications to the
.gitmodules file, both will be used by subsequent patches for the mv
and rm commands.
