Instead of discovering the .git/ directory, reading the config and then
trying to painstakingly reset all the global state if we did not find a
matching alias, let's use the early config machinery instead.
It may look like unnecessary work to discover the .git/ directory in the
early config machinery and then call setup_git_directory_gently() in the
case of a shell alias, repeating the very same discovery *again*.
However, we have to do this as the early config machinery takes pains
*not* to touch any global state, while shell aliases expect a possibly
changed working directory and at least the GIT_PREFIX and GIT_DIR
variables to be set.
This change also fixes a known issue where Git tried to read the pager
config from an incorrect path in a subdirectory of a Git worktree if an
alias expanded to a shell command.

When expanding aliases, the git_dir is set during the alias expansion
(by virtue of running setup_git_directory_gently()).
This git_dir may be relative to the current working directory, and
indeed often is simply ".git/".
When the alias expands to a shell command, we restore the original
working directory, though, yet we do not reset git_dir.
As a consequence, subsequent read_early_config() runs will mistake the
git_dir to be populated properly and not find the correct config.
Demonstrate this problem by adding a test case.

Git has this feature which suggests similar commands (including aliases)
in case the user specified an unknown command.
This feature currently relies on a side effect of the way we expand
aliases right now: when a command is not a builtin, we use the regular
config machinery (meaning: discovering the .git/ directory and
initializing global state such as the config cache) to see whether the
command refers to an alias.
However, we will change the way aliases are expanded in the next
commits, to use the early config instead. That means that the
autocorrect feature can no longer discover the available aliases by
looking at the config cache (because it has not yet been initialized).
So let's just use the early config machinery instead.
This is slightly less performant than the previous way, as the early
config is used *twice*: once to see whether the command refers to an
alias, and then to see what aliases are most similar. However, this is
hardly a performance-critical code path, so performance is less important
here.

When get_value() parses a key/value pair, it is possible that the line
number is decreased (because the \n has been consumed already) before the
key/value pair is passed to the callback function, to allow for the
correct line to be attributed in case of an error.
However, when git_parse_source() asks get_value() to parse the key/value
pair, the error reporting is performed *after* get_value() returns.
Which means that we have to be careful not to increase the line number
in get_value() after the callback function returned an error.

When discovering a .git/ directory, we take pains to ensure that its
repository format version matches Git's expectations, and we return NULL
otherwise.
However, we still appended the invalid path to the strbuf passed as
argument.
Let's just reset the strbuf to the state before we appended the .git/
directory that was eventually rejected.
There is another early return path in that function, when
setup_git_directory_gently_1() returns GIT_DIR_NONE or an error. In that
case, the gitdir parameter has not been touched, therefore there is no
need for an equivalent change in that code path.

The diff-so-fancy project is also written in perl, and most
of its users pipe diffs through both diff-highlight and
diff-so-fancy. It would be nice if this could be done in a
single script. So let's pull most of diff-highlight's code
into its own module which can be used by diff-so-fancy.
In addition, we'll abstract a few basic items like reading
from stdio so that a script using the module can do more
processing before or after diff-highlight handles the lines.
See the README update for more details.
One small downside is that the diff-highlight script must
now be built using the Makefile. There are ways around this,
but it quickly gets into perl arcana. Let's go with the
simple solution. As a bonus, our Makefile now respects the
PERL_PATH variable if it is set.

When illustrating how to normalize the line endings, the
documentation in gitattributes tells the user to `rm .git/index`.
This is incorrect for two reasons:
- Users shouldn't be instructed to mess around with the internal
implementation of Git using raw file system tools like `rm`.
- Within a submodule or an additional working tree `.git` is just a
file containing a `gitdir: <path>` pointer into the real `.git`
directory. Therefore `rm .git/index` does not work.
The purpose of the `rm .git/index` instruction is to remove all entries
from the index without touching the working tree. The way to do this
with Git is to use `read-tree --empty`.

In commit 46f0344 ("sha1_file: support reading from a loose object of
unknown type", 2015-05-06), "struct object_info" gained a "typename"
field that could represent a type name from a loose object file, whether
valid or invalid, as opposed to the existing "typep" which could only
represent valid types. Some relatively complex manipulations were added
to avoid breaking packed_object_info() without modifying it, but it is
much easier to just teach packed_object_info() about the new field.
Therefore, teach packed_object_info() as described above.

Some submodule tests do some setup outside of a test_expect
block. This is bad because we won't actually check the
outcome of those commands. But it's doubly so because "git
add submodule" now produces a warning to stderr, which is
not suppressed by the test scripts in non-verbose mode.
This patch does the minimal to fix the annoying warnings.
All three of these scripts could use more cleanup of related
setup.

It's an easy mistake to add a repository inside another
repository, like:
git clone $url
git add .
The resulting entry is a gitlink, but there's no matching
.gitmodules entry. Trying to use "submodule init" (or clone
with --recursive) doesn't do anything useful. Prior to
v2.13, such an entry caused git-submodule to barf entirely.
In v2.13, the entry is considered "inactive" and quietly
ignored. Either way, no clone of your repository can do
anything useful with the gitlink without the user manually
adding the submodule config.
In most cases, the user probably meant to either add a real
submodule, or they forgot to put the embedded repository in
their .gitignore file.
Let's issue a warning when we see this case. There are a few
things to note:
- the warning will go in the git-add porcelain; anybody
wanting to do low-level manipulation of the index is
welcome to create whatever funny states they want.
- we detect the case by looking for a newly added gitlink;
updates via "git add submodule" are perfectly reasonable,
and this avoids us having to investigate .gitmodules
entirely
- there's a command-line option to suppress the warning.
This is needed for git-submodule itself (which adds the
entry before adding any submodule config), but also
provides a mechanism for other scripts doing
submodule-like things.
We could make this a hard error instead of a warning.
However, we do add lots of sub-repos in our test suite. It's
not _wrong_ to do so. It just creates a state where users
may be surprised. Pointing them in the right direction with
a gentle hint is probably the best option.
There is a config knob that can disable the (long) hint. But
I intentionally omitted a config knob to disable the warning
entirely. Whether the warning is sensible or not is
generally about context, not about the user's preferences.
If there's a tool or workflow that adds gitlinks without
matching .gitmodules, it should probably be taught about the
new command-line option, rather than blanket-disabling the
warning.

ENOTDIR (less obvious). Instead of repeating comparison of errno
