9e2d884d0f config API: add "string" version of *_value_multi(), fix segfaults
Fix numerous and mostly long-standing segfaults in consumers of
the *_config_*value_multi() API. As discussed in the preceding commit
an empty key in the config syntax yields a "NULL" string, which these
users would give to strcmp() (or similar), resulting in segfaults.

As this change shows, most users users of the *_config_*value_multi()
API didn't really want such an an unsafe and low-level API, let's give
them something with the safety of git_config_get_string() instead.

This fix is similar to what the *_string() functions and others
acquired in[1] and [2]. Namely introducing and using a safer
"*_get_string_multi()" variant of the low-level "_*value_multi()"
function.

This fixes segfaults in code introduced in:

  - d811c8e17c (versionsort: support reorder prerelease suffixes, 2015-02-26)
  - c026557a37 (versioncmp: generalize version sort suffix reordering, 2016-12-08)
  - a086f921a7 (submodule: decouple url and submodule interest, 2017-03-17)
  - a6be5e6764 (log: add log.excludeDecoration config option, 2020-04-16)
  - 92156291ca (log: add default decoration filter, 2022-08-05)
  - 50a044f1e4 (gc: replace config subprocesses with API calls, 2022-09-27)

There are now two users ofthe low-level API:

- One in "builtin/for-each-repo.c", which we'll convert in a
  subsequent commit.

- The "t/helper/test-config.c" code added in [3].

As seen in the preceding commit we need to give the
"t/helper/test-config.c" caller these "NULL" entries.

We could also alter the underlying git_configset_get_value_multi()
function to be "string safe", but doing so would leave no room for
other variants of "*_get_value_multi()" that coerce to other types.

Such coercion can't be built on the string version, since as we've
established "NULL" is a true value in the boolean context, but if we
coerced it to "" for use in a list of strings it'll be subsequently
coerced to "false" as a boolean.

The callback pattern being used here will make it easy to introduce
e.g. a "multi" variant which coerces its values to "bool", "int",
"path" etc.

a428619309 config API: have *_multi() return an "int" and take a "dest"
Have the "git_configset_get_value_multi()" function and its siblings
return an "int" and populate a "**dest" parameter like every other
git_configset_get_*()" in the API.

As we'll take advantage of in subsequent commits, this fixes a blind
spot in the API where it wasn't possible to tell whether a list was
empty from whether a config key existed. For now we don't make use of
those new return values, but faithfully convert existing API users.

Most of this is straightforward, commentary on cases that stand out:

- To ensure that we'll properly use the return values of this function
  in the future we're using the "RESULT_MUST_BE_USED" macro introduced
  in [1].

  As git_die_config() now has to handle this return value let's have
  it BUG() if it can't find the config entry. As tested for in a
  preceding commit we can rely on getting the config list in
  git_die_config().

- The loops after getting the "list" value in "builtin/gc.c" could
  also make use of "unsorted_string_list_has_string()" instead of using
  that loop, but let's leave that for now.

- In "versioncmp.c" we now use the return value of the functions,
  instead of checking if the lists are still non-NULL.

values with configuration variables like "diff.noprefix", causing
receiving end of the patch that expects the standard -p1 format to

8d5213decf format-patch: add format.noprefix option
The previous commit dropped support for diff.noprefix in format-patch.
While this will do the right thing in most cases (where sending patches
without a prefix was an accidental side effect of the sender preferring
to see their local patches without prefixes), it left no good option for
a project or workflow where you really do want to send patches without
prefixes. You'd be stuck using "--no-prefix" for every invocation.

So let's add a config option specific to format-patch that enables this
behavior. That gives people who have such a workflow a way to get what
they want, but makes it hard to accidentally trigger it.

A more backwards-compatible way of doing the transition would be to have
format.noprefix default to diff.noprefix when it's not set. But that
doesn't really help the "accidental" problem; people would have to
manually set format.noprefix=false. And it's unlikely that anybody
really wants format.noprefix=true in the first place. I'm adding it here
mostly as an escape hatch, not because anybody has expressed any
interest in it.

c169af8f7a format-patch: do not respect diff.noprefix
The output of format-patch respects diff.noprefix, but this usually ends
up being a hassle for people receiving the patch, as they have to
manually specify "-p0" in order to apply it.

I don't think there was any specific intention for it to behave this
way. The noprefix option is handled by git_diff_ui_config(), and
format-patch exists in a gray area between plumbing and porcelain.
People do look at the output, and we'd expect it to colorize things,
respect their choice of algorithm, and so on. But this particular option
creates problems for the receiver (in theory so does diff.mnemonicprefix,
but since we are always formatting commits, the mnemonic prefixes will
always be "a/" and "b/").

So let's disable it. The slight downsides are:

  - people who have set diff.noprefix presumably like to see their
    patches without prefixes. If they use format-patch to review their
    series, they'll see prefixes. On the other hand, it is probably a
    good idea for them to look at what will actually get sent out.

    We could try to play games here with "is stdout a tty", as we do for
    color. But that's not a completely reliable signal, and it's
    probably not worth the trouble. If you want to see the patch with
    the usual bells and whistles, then you are better off using "git
    log" or "git show".

  - if a project really does have a workflow that likes prefix-less
    patches, and the receiver is prepared to use "-p0", then the sender
    now has to manually say "--no-prefix" for each format-patch
    invocation. That doesn't seem _too_ terrible given that the receiver
    has to manually say "-p0" for each git-am invocation.

36bf195890 alloc.h: move ALLOC_GROW() functions from cache.h
This allows us to replace includes of cache.h with includes of the much
smaller alloc.h in many places.  It does mean that we also need to add
includes of alloc.h in a number of C files.

50bebf98d9 format.attach: allow empty value to disable multi-part messages
When a lower precedence configuration file (e.g. /etc/gitconfig)
defines format.attach in any way, there was no way to disable it in
a more specific configuration file (e.g. $HOME/.gitconfig).

Change the behaviour of setting it to an empty string.  It used to
mean that the result is still a multipart message with only dashes
used as a multi-part separator, but now it resets the setting to
the default (which would be to give an inline patch, unless other
command line options are in effect).

fd2d4c135e gpg-interface: lazily initialize and read the configuration
Instead of forcing the porcelain commands to always read the
configuration variables related to the signing and verifying
signatures, lazily initialize the necessary subsystem on demand upon
the first use.

This hopefully would make it more future-proof as we do not have to
think and decide whether we should call git_gpg_config() in the
git_config() callback for each command.

A few git_config() callback functions that used to be custom
callbacks are now just a thin wrapper around git_default_config().
We could further remove, git_FOO_config and replace calls to
git_config(git_FOO_config) with git_config(git_default_config), but
to make it clear which ones are affected and the effect is only the
removal of git_gpg_config(), it is vastly preferred not to do such a
change in this step (they can be done on top once the dust settled).

Plug a small leak.

5b8db44bdd format-patch: unleak "-v <num>"
The "subject_prefix" member of "struct revision" usually is set to a
borrowed string (either a string literal like "PATCH" that appear in
the program text as a hardcoded default, or the value of
"format.subjectprefix") and is never freed when the containing
revision structure is released.  The "-v <num>" codepath however
violates this rule and stores a pointer to an allocated string to
this member, relinquishing the responsibility to free it when it is
done using the revision structure, leading to a small one-time leak.

Instead, keep track of the string it allocates to let the revision
structure borrow, and clean it up when it is done.

4810946f60 format-patch: support format.mboxrd with --stdout
mboxrd is a more robust output format when used with --stdout
and needs more exposure.  Introducing this config knob lets
users choose the more robust format for all their --stdout
uses.

Relying on --pretty=mboxrd and including all of pretty-formats.txt
in the `git format-patch' documentation would likely be
confusing to users.  Furthermore, this setting is useful across
multiple invocations.  So introduce `format.mboxrd' as a boolean
configuration knob that changes the default --pretty=email format
to --pretty=mboxrd when (and only when) --stdout is in use.

Adding "USE_THE_INDEX_COMPATIBILITY_MACROS" to these two appears to
have been unnecessary from the start, as going back and compiling
f8adbec9fe (cache.h: flip NO_THE_INDEX_COMPATIBILITY_MACROS switch,

Let's not have these ask for the compatibility macros from cache.h

Extract a function which finishes setting up the shortlog struct for
use. The caller in `make_cover_letter()` does not care about trailer
sorting, so it isn't strictly necessary to add a call there in this
patch.

But the next patch will add additional functionality to the new
`shortlog_finish_setup()` function, which the caller in
`make_cover_letter()` will care about.

5cf88fd8b0 git-compat-util.h: use "UNUSED", not "UNUSED(var)"
As reported in [1] the "UNUSED(var)" macro introduced in
2174b8c75d (Merge branch 'jk/unused-annotation' into next,
2022-08-24) breaks coccinelle's parsing of our sources in files where
it occurs.

Let's instead partially go with the approach suggested in [2] of
making this not take an argument. As noted in [1] "coccinelle" will
ignore such tokens in argument lists that it doesn't know about, and
it's less of a surprise to syntax highlighters.

This undoes the "help us notice when a parameter marked as unused is
actually use" part of 9b24034754 (git-compat-util: add UNUSED macro,
2022-08-19), a subsequent commit will further tweak the macro to
implement a replacement for that functionality.
