"git ls-files -k" needs to crawl only the part of the working tree
that may overlap the paths in the index to find killed files, but
shared code with the logic to find all the untracked files, which
made it unnecessarily inefficient.
* jc/ls-files-killed-optim:
dir.c::test_one_path(): work around directory_exists_in_index_icase() breakage
t3010: update to demonstrate "ls-files -k" optimization pitfalls
ls-files -k: a directory only can be killed if the index has a non-directory
dir.c: use the cache_* macro to access the current index

directory_exists_in_index() takes pathname and its length, but its
helper function directory_exists_in_index_icase() reads one byte
beyond the end of the pathname and expects there to be a '/'.
This needs to be fixed, as that one-byte-beyond-the-end location may
not even be readable, possibly by not registering directories to
name hashes with trailing slashes. In the meantime, update the new
caller added recently to treat_one_path() to make sure that the path
buffer it gives the function is one byte longer than the path it is
asking the function about by appending a slash to it.

An earlier draft of the previous step used cache_name_exists() to
check the directory we were looking at, which missed the second case
described in its log message. Demonstrate why it is not sufficient.

When the working tree walker encounters a directory, it asks the
function treat_directory() if it should descend into it, show it as
an untracked directory, or do something else. When the directory is
the top of the submodule working tree, we used to say "That is an
untracked directory", which was bogus.
It is an entity that is tracked in the index of the repository we
are looking at, and that is not to be descended into it. Return
path_none, not path_untracked, to report that.
The existing case that path_untracked is returned for a newly
discovered submodule that is not tracked in the index (this only
happens when DIR_NO_GITLINKS option is not used) is unchanged, but
that is exactly because the submodule is not tracked in the index.

There are many instances where the treatment of symbolic links in the
object model and the algorithms are tested, but where it is not
necessary to actually have a symbolic link in the worktree. Make
adjustments to the tests and remove the SYMLINKS prerequisite when
appropriate in trivial cases, where "trivial" means:
- merely a replacement of 'ln -s a b && git add b' by test_ln_s_add
is needed;
- a test for symbolic link on the file system can be split off (and
remains protected by SYMLINKS);
- existing code is equivalent to test_ln_s_add.

In particular:
- move test preparations inside test_expect_success
- place test description on the test_expect_success line
- indent with a tab

Many tests depend on that symbolic links work. This introduces a check
that sets the prerequisite tag SYMLINKS if the file system supports
symbolic links. Since so many tests have to check for this prerequisite,
we do the check in test-lib.sh, so that we don't need to repeat the test
in many scripts.
To check for 'ln -s' failures, you can use a FAT partition on Linux:
$ mkdosfs -C git-on-fat 1000000
$ sudo mount -o loop,uid=j6t,gid=users,shortname=winnt git-on-fat /mnt
Clone git to /mnt and
$ GIT_SKIP_TESTS='t0001.1[34] t0010 t1301 t403[34] t4129.[47] t5701.7
t7701.3 t9100 t9101.26 t9119 t9124.[67] t9200.10 t9600.6' \
make test
(These additionally skipped tests depend on POSIX permissions that FAT on
Linux does not provide.)

Several old tests were written before test_cmp was introduced, convert
these to test_cmp.
If were are at it, fix the order of the arguments where necessary to
make expected come first, so the command shows how the test result
deviates from the correct output.

Add -m/--modified to show files that have been modified wrt. the index.
[jc: The original came from Brian Gerst on Sep 1st but it only checked
if the paths were cache dirty without actually checking the files were
modified. I also added the usage string and a new test.]
