We parse diff.wsErrorHighlight in git_diff_ui_config(), meaning that it
doesn't take effect for plumbing commands, only for porcelains like
git-diff itself. This is mildly annoying as it means scripts like
add--interactive, which produce a user-visible diff with color, don't
respect the option.
We could teach that script to parse the config and pass it along as
--ws-error-highlight to the diff plumbing. But there's a simpler
solution.
It should be reasonably safe for plumbing to respect this option, as it
only kicks in when color is otherwise enabled. And anybody parsing
colorized output must already deal with the fact that color.diff.* may
change the exact output they see; those options have been part of
git_diff_basic_config() since its inception in 9a1805a872 (add a "basic"
diff config callback, 2008-01-04).
So we can just move it to the "basic" config, which fixes
add--interactive, along with any other script in the same boat, with a
very low risk of hurting any plumbing users.

Make the diffstat interface (namely, the diffstat_t struct and
compute_diffstat) no longer be internal to diff.c and allow it to be used
by other parts of git.
This is helpful for code that may want to easily extract information
from files using the diff machinery, while flushing it differently from
how the show_* functions used by diff_flush() do it. One example is the
builtin implementation of git-add--interactive's status.

Since these macros already take a `keyvar' pointer of a known type,
we can rely on OFFSETOF_VAR to get the correct offset without
relying on non-portable `__typeof__' and `offsetof'.
Argument order is also rearranged, so `keyvar' and `member' are
sequential as they are used as: `keyvar->member'

While we cannot rely on a `__typeof__' operator being portable
to use with `offsetof'; we can calculate the pointer offset
using an existing pointer and the address of a member using
pointer arithmetic for compilers without `__typeof__'.
This allows us to simplify usage of hashmap iterator macros
by not having to specify a type when a pointer of that type
is already given.
In the future, list iterator macros (e.g. list_for_each_entry)
may also be implemented using OFFSETOF_VAR to save hackers the
trouble of using container_of/list_entry macros and without
relying on non-portable `__typeof__'.

`hashmap_free_entries' behaves like `container_of' and passes
the offset of the hashmap_entry struct to the internal
`hashmap_free_' function, allowing the function to free any
struct pointer regardless of where the hashmap_entry field
is located.
`hashmap_free' no longer takes any arguments aside from
the hashmap itself.

Using `container_of' can be verbose and choosing names for
intermediate "struct hashmap_entry" pointers is a hard problem.
So introduce "*_entry" APIs inspired by similar linked-list
APIs in the Linux kernel.
Unfortunately, `__typeof__' is not portable C, so we need an
extra parameter to specify the type.

In 7fbbcb21b1 ("diff: batch fetching of missing blobs", 2019-04-08),
diff was taught to batch the fetching of missing objects when operating
on a partial clone, but was not taught to refrain from fetching
GITLINKs. Teach diff to check if an object is a GITLINK before including
it in the set to be fetched.
(As stated in the commit message of that commit, unpack-trees was also
taught a similar thing prior, but unpack-trees correctly checks for
GITLINK before including objects in the set to be fetched.)

The line count in the outer diff's hunk headers of a range diff is not
all that interesting. It merely shows how far along the inner diff
are on both sides. That number is of no use for human readers, and
range-diffs are not meant to be machine readable.
In a subsequent commit we're going to add some more contextual
information such as the filename corresponding to the diff to the hunk
headers. Remove the unnecessary information, and just keep the "@@"
to indicate that a new hunk of the outer diff is starting.

When running an external diff from, say, a diff tool, it is safe to
assume that we want to write the files in question. On Windows, that
means that there cannot be any other process holding an open handle to
said files, or even just a mapped region.
So let's make sure that `git diff` itself is not holding any open handle
to the files in question.
In fact, we will just release the file pair right away, as the external
diff uses the files we just wrote, so we do not need to hold the file
contents in memory anymore.

Instead of using the repository_format_partial_clone global
and fetch_objects() directly, let's use has_promisor_remote()
and promisor_remote_get_direct().
This way all the configured promisor remotes will be taken
into account, not only the one specified by
extensions.partialClone.
Also when cloning or fetching using a partial clone filter,
remote.origin.promisor will be set to "true" instead of
setting extensions.partialClone to "origin". This makes it
possible to use many promisor remote just by fetching from
them.

Before d473e2e0e8 (diff.c: convert -U|--unified, 2019-01-27), -U and
--unified are implemented with a custom parser opt_arg() in diff.c. I
didn't check this code carefully and not realize that it's the
equivalent of PARSE_OPT_NONEG | PARSE_OPT_OPTARG.
In other words, if -U is specified without any argument, the option
should be accepted, and the default value should be used. Without
PARSE_OPT_OPTARG, parse_options() will reject this case and cause a
regression.
