Move 'repository_format_worktree_config' out of the global scope and into
the 'repository' struct. This change is similar to how
'repository_format_partial_clone' was moved in ebaf3bcf1a (repository: move
global r_f_p_c to repo struct, 2021-06-17), adding it to the 'repository'
struct and updating 'setup.c' & 'repository.c' functions to assign the value
appropriately.
The primary goal of this change is to be able to load the worktree config of
a submodule depending on whether that submodule - not its superproject - has
'extensions.worktreeConfig' enabled. To ensure 'do_git_config_sequence()'
has access to the newly repo-scoped configuration, add a 'struct repository'
argument to 'do_git_config_sequence()' and pass it the 'repo' value from
'config_with_options()'.
Finally, add/update tests in 't3007-ls-files-recurse-submodules.sh' to
verify 'extensions.worktreeConfig' is read an used independently by
superprojects and submodules.

Add a 'struct repository' argument to 'config_with_options()' and remove the
'repo' field from 'struct git_config_source'.
A 'struct repository' instance was originally added to the config source in
e3e8bf046e (submodule-config: pass repo upon blob config read, 2021-08-16)
to improve how submodule blob config content was accessed. At the time, this
was the only use for a 'repository' instance, so it was naturally added only
where it was needed: to 'struct git_config_source'. However, in upcoming
patches, 'config_with_options()' will need the repository instance to access
extension information (regardless of whether a 'config_source' exists). To
make the 'struct repository' instance more easily accessible, move it into
the function's arguments.
Update all callers of 'config_with_options()' to pass the appropriate 'repo'
value:
* in 'builtin/config.c', use 'the_repository'
* in 'submodule--config.c', use the 'repo' arg in 'config_from_gitmodules()'
* in 'read_[very_]early_config()' & 'read_protected_config()', set 'repo' to
NULL (repository instances aren't available there)
* in 'populate_remote_urls()', use the repo instance that has been added to
the 'struct config_include_data'
* in 'repo_read_config()', use the given 'repo' arg
Finally, note that this patch eliminates the fallback to 'the_repository'
that previously existed for the 'config_source' repo instance if it was
NULL. The fallback is no longer necessary, as the 'repo' is set explicitly
in all cases where it is needed.

hash.h depends upon and includes repository.h, due to the definition and
use of the_hash_algo (defined as the_repository->hash_algo). However,
most headers trying to include hash.h are only interested in the layout
of the structs like object_id. Move the parts of hash.h that do not
depend upon repository.h into a new file hash-ll.h (the "low level"
parts of hash.h), and adjust other files to use this new header where
the convenience inline functions aren't needed.
This allows hash.h and object.h to be fairly small, minimal headers. It
also exposes a lot of hidden dependencies on both path.h (which was
brought in by repository.h) and repository.h (which was previously
implicitly brought in by object.h), so also adjust other files to be
more explicit about what they depend upon.

For a lot of uses of UNLEAK() it would be quite tricky to release the
memory involved, or we're missing the relevant *_(release|clear)()
functions. But in these cases we have them already, and can just
invoke them on the variable(s) involved, instead of UNLEAK().
For "builtin/worktree.c" the UNLEAK() was also added in [1], but the
struct member it's unleaking was removed in [2]. The only non-"int"
member of that structure is "const char *keep_locked", which comes to
us via "argv" or a string literal[3].
We have good visibility via the compiler and
tooling (e.g. SANITIZE=address) on bad free()-ing, but none on
UNLEAK() we don't need anymore. So let's prefer releasing the memory
when it's easy.
For "bugreport", "worktree" and "config" we need to start using a "ret
= ..." return pattern. For "builtin/bugreport.c" these UNLEAK() were
added in [4], and for "builtin/config.c" in [1].
For "config" the code seen here was the only user of the "value"
variable. For "ACTION_{RENAME,REMOVE}_SECTION" we need to be sure to
return the right exit code in the cases where we were relying on
falling through to the top-level.
I think there's still a use-case for UNLEAK(), but hat it's changed
since then. Using it so that "we can see the real leaks" is
counter-productive in these cases.
It's more useful to have UNLEAK() be a marker of the remaining odd
cases where it's hard to free() the memory for whatever reason. With
this change less than 20 of them remain in-tree.

The 'git config' builtin takes a 'value-pattern' parameter for several
actions. This can cause confusion when expecting exact value matches
instead of regex matches, especially when the input string contains
metacharacters. While callers can escape the patterns themselves, it
would be more friendly to allow an argument to disable the pattern
matching in favor of an exact string match.
Add a new '--fixed-value' option that does not currently change the
behavior. The implementation will be filled in by later changes for
each appropriate action. For now, check and test that --fixed-value
will abort the command when included with an incompatible action or
without a 'value-pattern' argument.
The name '--fixed-value' was chosen over something simpler like
'--fixed' because some commands allow regular expressions on the
key in addition to the value.

The 'value_regex' argument in the 'git config' builtin is poorly named,
especially related to an upcoming change that allows exact string
matches instead of ERE pattern matches.
Perform a mostly mechanical change of every instance of 'value_regex' to
'value_pattern' in the codebase. This is only critical for documentation
and error messages, but it is best to be consistent inside the codebase,
too.
For documentation, use 'value-pattern' which is better punctuation. This
affects Documentation/git-config.txt and the usage in builtin/config.c,
which was already mixed between 'value_regex' and 'value-regex'.
I gave some thought to leaving the value_regex variables inside config.c
that are regex_t pointers. However, it is probably best to keep the name
consistent with the rest of the variables.
This does not update the translations inside the po/ directory, as that
creates conflicts with ongoing work. The input strings should
automatically update through automation, and a few of the output strings
currently use "[value_regex]" directly.

A new repo extension is added, worktreeConfig. When it is present:
- Repository config reading by default includes $GIT_DIR/config _and_
$GIT_DIR/config.worktree. "config" file remains shared in multiple
worktree setup.
- The special treatment for core.bare and core.worktree, to stay
effective only in main worktree, is gone. These config settings are
supposed to be in config.worktree.
This extension is most useful in multiple worktree setup because you
now have an option to store per-worktree config (which is either
.git/config.worktree for main worktree, or
.git/worktrees/xx/config.worktree for linked ones).
This extension can be used in single worktree mode, even though it's
pretty much useless (but this can happen after you remove all linked
worktrees and move back to single worktree).
"git config" reads from both "config" and "config.worktree" by default
(i.e. without either --user, --file...) when this extension is
present. Default writes still go to "config", not "config.worktree". A
new option --worktree is added for that (*).
Since a new repo extension is introduced, existing git binaries should
refuse to access to the repo (both from main and linked worktrees). So
they will not misread the config file (i.e. skip the config.worktree
part). They may still accidentally write to the config file anyway if
they use with "git config --file <path>".
This design places a bet on the assumption that the majority of config
variables are shared so it is the default mode. A safer move would be
default writes go to per-worktree file, so that accidental changes are
isolated.
(*) "git config --worktree" points back to "config" file when this
extension is not present and there is only one worktree so that it
works in any both single and multiple worktree setups.

As reported here[0], Microsoft Visual Studio 2017.2 and "gcc -pedantic"

They insist on an array size:
d:\git\src\builtin\config.c(70,46): error C2133: 'builtin_config_options': unknown size
The thread [1] explains that this is due to the single-pass nature of
old compilers.
To work around this error, introduce the forward-declared function
usage_builtin_config() instead that uses the array
builtin_config_options only after it has been defined.
Also use this function in all other places where usage_with_options() is
called with the same arguments.

As of this commit, the canonical way to retreive an ANSI-compatible
color escape sequence from a configuration file is with the
`--get-color` action.
This is to allow Git to "fall back" on a default value for the color
should the given section not exist in the specified configuration(s).
With the addition of `--default`, this is no longer needed since:
$ git config --default red --type=color core.section
will be have exactly as:
$ git config --get-color core.section red
For consistency, let's introduce `--type=color` and encourage its use
with `--default` together over `--get-color` alone.

For some use cases, callers of the `git-config(1)` builtin would like to
fallback to default values when the variable asked for does not exist.
In addition, users would like to use existing type specifiers to ensure
that values are parsed correctly when they do exist in the
configuration.
For example, to fetch a value without a type specifier and fallback to
`$fallback`, the following is required:
$ git config core.foo || echo "$fallback"
This is fine for most values, but can be tricky for difficult-to-express
`$fallback`'s, like ANSI color codes.
This motivates `--get-color`, which is a one-off exception to the normal
type specifier rules wherein a user specifies both the configuration
variable and an optional fallback. Both are formatted according to their
type specifier, which eases the burden on the user to ensure that values
are correctly formatted.
This commit (and those following it in this series) aim to eventually
replace `--get-color` with a consistent alternative. By introducing
`--default`, we allow the `--get-color` action to be promoted to a
`--type=color` type specifier, retaining the "fallback" behavior via the
`--default` flag introduced in this commit.
For example, we aim to replace:
$ git config --get-color variable [default] [...]
with:
$ git config --default default --type=color variable [...]
Values filled by `--default` behave exactly as if they were present in
the affected configuration file; they will be parsed by type specifiers
without the knowledge that they are not themselves present in the
configuration.
Specifically, this means that the following will work:
$ git config --int --default 1M does.not.exist
1048576
In subsequent commits, we will offer `--type=color`, which (in
conjunction with `--default`) will be sufficient to replace
`--get-color`.

canonicalized under that type.
In another series, we propose to extend this functionality with
`--type=color` and `--default` to replace `--get-color`.
However, we traditionally use `--color` to mean "colorize this output",
instead of "this value should be treated as a color".
Currently, `git config` does not support this kind of colorization, but
we should be careful to avoid squatting on this option too soon, so that
`git config` can support `--color` (in the traditional sense) in the
future, if that is desired.
In this patch, we support `--type=<int|bool|bool-or-int|...>` in
addition to `--int`, `--bool`, and etc. This allows the aforementioned
upcoming patch to support querying a color value with a default via
`--type=color --default=...`, without squandering `--color`.
We retain the historic behavior of complaining when multiple,
legacy-style `--<type>` flags are given, as well as extend this to
conflicting new-style `--type=<type>` flags. `--int --type=int` (and its
commutative pair) does not complain, but `--bool --type=int` (and its
commutative pair) does.

Internally, we represent `git config`'s type specifiers as a bitset
using OPT_BIT. 'bool' is 1<<0, 'int' is 1<<1, and so on. This technique
allows for the representation of multiple type specifiers in the `int
types` field, but this multi-representation is left unused.
In fact, `git config` will not accept multiple type specifiers at a
time, as indicated by:
$ git config --int --bool some.section
error: only one type at a time.
This patch uses `OPT_SET_INT` to prefer the _last_ mentioned type
specifier, so that the above command would instead be valid, and a
synonym of:
$ git config --bool some.section
This change is motivated by two urges: (1) it does not make sense to
represent a singular type specifier internally as a bitset, only to
complain when there are multiple bits in the set. `OPT_SET_INT` is more
well-suited to this task than `OPT_BIT` is. (2) a future patch will
introduce `--type=<type>`, and we would like not to complain in the
following situation:
$ git config --int --type=int

This is similar to ff1e72483 (tag: change default of `pager.tag` to
"on", 2017-08-02) and is safe now that we do not consider `pager.config`
at all when we are not listing or getting configuration. This change
will help with listing large configurations, but will not hurt users of
`git config --edit` as it would have before the previous commit.
