On a sparse checked out repository, `git grep` (without --cached) ends
up searching the cache when an entry matches the search pathspec and has
the SKIP_WORKTREE bit set. This is confusing both because the sparse
paths are not expected to be in a working tree search (as they are not
checked out), and because the output mixes working tree and cache
results without distinguishing them. (Note that grep also resorts to the
cache on working tree searches that include --assume-unchanged paths.
But the whole point in that case is to assume that the contents of the
index entry and the file are the same. This does not apply to the case
of sparse paths, where the file isn't even expected to be present.)
Fix that by teaching grep to honor the sparse-checkout rules for working
tree searches. If the user wants to grep paths outside the current
sparse-checkout definition, they may either update the sparsity rules to
materialize the files, or use --cached to search all blobs registered in
the index.
Note: it might also be interesting to add a configuration option that
allow users to search paths that are present despite having the
SKIP_WORKTREE bit set, and/or to restrict searches in the index and past
revisions too. These ideas are left as future improvements to avoid
conflicting with other sparse-checkout topics currently in flight.

Switch all uses of $_z40 to $ZERO_OID so that they work correctly with
larger hashes. This commit was created by using the following sed
command to modify all files in the t directory except t/test-lib.sh:
sed -i 's/\$_z40/$ZERO_OID/g'

Similar to $EMPTY_TREE this makes it easier to recognize this special
SHA-1 and change hash later.

The option is spelled '--deleted'.

There is no need to duplicate the definition of $_z40 and $_x40 that
test-lib.sh supplies the test scripts.

Commit b4d1690 (Teach Git to respect skip-worktree bit (reading part))
fails to make "git commit -- a b c" respect skip-worktree
(i.e. not committing paths that are skip-worktree). This is because
when the index is reset back to HEAD, all skip-worktree information is
gone.
This patch saves skip-worktree information in the string list of
committed paths, then reuse it later on to skip skip-worktree paths.

grep: turn on --cached for files that is marked skip-worktree
ls-files: do not check for deleted file that is marked skip-worktree
update-index: ignore update request if it's skip-worktree, while still allows removing
diff*: skip worktree version
