The `struct string_list branch_list` is declared as `NODUP`, which makes
it not copy strings inserted into it. This causes memory leaks though,
as this means it also won't be responsible for _freeing_ inserted
strings. Thus, every branch we add to this will leak.
Fix this by marking the list as `DUP` instead and free the local copy we
have of the variable.

When we want to know the push urls for a remote, there is some simple
logic:
- if the user configured any remote.*.pushurl keys, then those make
the complete set of push urls
- otherwise we push to all urls in remote.*.url
Many spots implement this with a level of indirection, assigning to a
local url/url_nr pair. But since both arrays are now strvecs, we can
just use a pointer to select the appropriate strvec, shortening the code
a bit.
Even though this is now a one-liner, since it is application logic that
is present in so many places, it's worth abstracting a helper function.
In fact, we already have such a function, but it's local to
builtin/push.c. So we'll just make it available everywhere via remote.h.
There are two spots to pay special attention to here:
1. in builtin/remote.c's get_url(), we are selecting first based on
push_mode and then falling back to "url" when we're in push_mode
but no pushurl is defined. The updated code makes that much more
clear, compared to the original which had an "else" fall-through.
2. likewise in that file's set_url(), we _only_ respect push_mode,
sine the point is that we are adding to pushurl in that case
(whether it is empty or not). And thus it does not use our helper
function.

Now that the url/pushurl fields of "struct remote" own their strings, we
can switch from bare arrays to strvecs. This has a few advantages:
- push/clear are now one-liners
- likewise the free+assigns in alias_all_urls() can use
strvec_replace()
- we now use size_t for storage, avoiding possible overflow
- this will enable some further cleanups in future patches
There's quite a bit of fallout in the code that reads these fields, as
it tends to access these arrays directly. But it's mostly a mechanical
replacement of "url_nr" with "url.nr", and "url[i]" with "url.v[i]",
with a few variations (e.g. "*url" could become "*url.v", but I used
"url.v[0]" for consistency).

In `get_head_names()`, we assign the "refs/heads/*" string constant to
`struct refspec_item::{src,dst}`, which are both non-constant pointers.
Ideally, we'd refactor the code such that both of these fields were
constant. But `struct refspec_item` is used for two different usecases
with conflicting requirements:
- To query for a source or destination based on the given refspec. The
caller either sets `src` or `dst` as the branch that we want to
search for, and the respective other field gets populated. The
fields should be constant when being used as a query parameter,
which is owned by the caller, and non-constant when being used as an
out parameter, which is owned by the refspec item. This is is
contradictory in itself already.
- To store refspec items with their respective source and destination
branches, in which case both fields should be owned by the struct.
Ideally, we'd split up this interface to clearly separate between
querying and storing, which would enable us to clarify lifetimes of the
strings. This would be a much bigger undertaking though.
Instead, accept the status quo for now and cast away the constness of
the source and destination patterns. We know that those are not being
written to or freed, so while this is ugly it certainly is fine for now.

Add a new "const struct config_context *ctx" arg to config_fn_t to hold
additional information about the config iteration operation.
config_context has a "struct key_value_info kvi" member that holds
metadata about the config source being read (e.g. what kind of config
source it is, the filename, etc). In this series, we're only interested
in .kvi, so we could have just used "struct key_value_info" as an arg,
but config_context makes it possible to add/adjust members in the future
without changing the config_fn_t signature. We could also consider other
ways of organizing the args (e.g. moving the config name and value into
config_context or key_value_info), but in my experiments, the
incremental benefit doesn't justify the added complexity (e.g. a
config_fn_t will sometimes invoke another config_fn_t but with a
different config value).
In subsequent commits, the .kvi member will replace the global "struct
config_reader" in config.c, making config iteration a global-free
operation. It requires much more work for the machinery to provide
meaningful values of .kvi, so for now, merely change the signature and
call sites, pass NULL as a placeholder value, and don't rely on the arg
in any meaningful way.
Most of the changes are performed by
contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every
config_fn_t:
- Modifies the signature to accept "const struct config_context *ctx"
- Passes "ctx" to any inner config_fn_t, if needed
- Adds UNUSED attributes to "ctx", if needed
Most config_fn_t instances are easily identified by seeing if they are
called by the various config functions. Most of the remaining ones are
manually named in the .cocci patch. Manual cleanups are still needed,
but the majority of it is trivial; it's either adjusting config_fn_t
that the .cocci patch didn't catch, or adding forward declarations of
"struct config_context ctx" to make the signatures make sense.
The non-trivial changes are in cases where we are invoking a config_fn_t
outside of config machinery, and we now need to decide what value of
"ctx" to pass. These cases are:
- trace2/tr2_cfg.c:tr2_cfg_set_fl()
This is indirectly called by git_config_set() so that the trace2
machinery can notice the new config values and update its settings
using the tr2 config parsing function, i.e. tr2_cfg_cb().
- builtin/checkout.c:checkout_main()
This calls git_xmerge_config() as a shorthand for parsing a CLI arg.
This might be worth refactoring away in the future, since
git_xmerge_config() can call git_default_config(), which can do much
more than just parsing.
Handle them by creating a KVI_INIT macro that initializes "struct
key_value_info" to a reasonable default, and use that to construct the
"ctx" arg.

We return an error when trying to rename a remote that has no fetch

fatal: could not unset 'remote.foo.fetch'
To make things even more confusing, we actually _do_ complete the config
modification, via git_config_rename_section(). After that we try to
rewrite the fetch refspec (to say refs/remotes/foo instead of origin).
But our call to git_config_set_multivar() to remove the existing entries
fails, since there aren't any, and it calls die().
We could fix this by using the "gently" form of the config call, and
checking the error code. But there is an even simpler fix: if we know
that there are no refspecs to rewrite, then we can skip that part
entirely.

The "git remote rm" command's option parsing is fairly primitive: it
insists on a single argument, which it treats as the remote name, and
displays a usage message otherwise.
This is OK, and maybe even convenient, as you could run:
git remote rm --foo
to drop a remote named "--foo". But it's also weirdly unlike most of the
rest of Git, which would complain that there is no option "--foo". The
right way to spell it by our conventions is:
git remote rm -- --foo
but this doesn't currently work.
So let's bring the command in line with the rest of Git (including its
sibling subcommands!) by feeding argv to parse_options(). We already
have an empty options array for the usage helper.
Note that we have to adjust the argc index down by one, as
parse_options() eats the program name from the start of the array.

Recent commits such as bf0a6b65fc (builtin/multi-pack-index.c: let
parse-options parse subcommands, 2022-08-19) converted a few functions
to match our usual argc/argv/prefix conventions, but the prefix argument
remains unused.
However, there is a good use for it: they should pass it to their own
parse_options() functions, where it may be used to adjust the value of
any filename options. In all but one of these functions, there's no
behavior change, since they don't use OPT_FILENAME. But this is an
actual fix for one option, which you can see by modifying the test suite
like so:
diff --git a/t/t5326-multi-pack-bitmaps.sh b/t/t5326-multi-pack-bitmaps.sh

I'd emphasize that this wasn't broken by bf0a6b65fc; it has been broken
all along, because the sub-function never got to see the prefix. It is
that commit which is actually enabling us to fix it (and which also
brought attention to the problem because it triggers -Wunused-parameter!)
The other functions changed here don't use OPT_FILENAME at all. In their
cases this isn't fixing anything visible, but it's following the usual
pattern and future-proofing them against somebody adding new options and
being surprised.
I didn't include a test for the one visible case above. We don't
generally test routine parse-options behavior for individual options.
The challenge here was finding the problem, and now that this has been
done, it's not likely to regress. Likewise, we could apply the patch
above to cover it "for free" but it makes reading the rest of the test
unnecessarily complicated.

The callback passed to git_config() must conform to a particular
interface. But most callbacks don't actually look at the extra "void
*data" parameter. Let's mark the unused parameters to make
-Wunused-parameter happy.
Note there's one unusual case here in get_remote_default() where we
actually ignore the "value" parameter. That's because it's only checking
whether the option is found at all, and not parsing its value.

Functions used with for_each_ref(), etc, need to conform to the
each_ref_fn interface. But most of them don't need every parameter;
let's annotate the unused ones to quiet -Wunused-parameter.

'git remote' parses its subcommands with a long list of if-else if
statements. parse-options has just learned to parse subcommands, so
let's use that facility instead, with the benefits of shorter code,
handling unknown subcommands, and listing subcommands for Bash
completion. Make sure that the default operation mode doesn't accept
any arguments; and while at it remove the capitalization of the error
message and adjust the test checking it accordingly.
Note that 'git remote' has both 'remove' and 'rm' subcommands, and the
former is preferred [1], so hide the latter for completion.
Note also that the functions implementing each subcommand only accept
the 'argc' and '**argv' parameters, so add a (unused) '*prefix'
parameter to make them match the type expected by parse-options, and
thus avoid casting a bunch of function pointers.

Since 4a4b4cda (builtin-remote: Make "remote -v" display push urls,
2009-06-13), the string_list that was initialized with 0 in its
strdup_string member is immediately made to strdup its key strings
by flipping the strdup_string member to true. When 183113a5
(string_list: Add STRING_LIST_INIT macro and make use of it.,
2010-07-04) has introduced STRING_LIST_INIT macros, it mechanically
replaced the initialization to STRING_LIST_INIT_NODUP.
Instead, just use the other initialization macro to make it strdup
the key from the beginning.

By default, the git remote show command will query data from remotes to
show data about what might be done on a future git fetch. This process
currently does not handle negative refspecs. This can be confusing,
because the show command will list refs as if they would be fetched. For
example if the fetch refspec "^refs/heads/pr/*", it still displays the
following:
* remote jdk19
Fetch URL: git@github.com:openjdk/jdk19.git
Push URL: git@github.com:openjdk/jdk19.git
HEAD branch: master
Remote branches:
master tracked
pr/1 new (next fetch will store in remotes/jdk19)
pr/2 new (next fetch will store in remotes/jdk19)
pr/3 new (next fetch will store in remotes/jdk19)
Local ref configured for 'git push':
master pushes to master (fast-forwardable)
Fix this by adding an additional check inside of get_ref_states. If a
ref matches one of the negative refspecs, mark it as skipped instead of
marking it as new or tracked.
With this change, we now report remote branches that are skipped due to
negative refspecs properly:
* remote jdk19
Fetch URL: git@github.com:openjdk/jdk19.git
Push URL: git@github.com:openjdk/jdk19.git
HEAD branch: master
Remote branches:
master tracked
pr/1 skipped
pr/2 skipped
pr/3 skipped
Local ref configured for 'git push':
master pushes to master (fast-forwardable)
By showing the refs as skipped, it helps clarify that these references
won't actually be fetched.
This does not properly handle refs going stale due to a newly added
negative refspec. In addition, git remote prune doesn't handle that
negative refspec case either. Fixing that requires digging into
get_stale_heads and handling the case of a ref which exists on the
remote but is omitted due to a negative refspec locally.
Add a new test case which covers the functionality above, as well as a
new expected failure indicating the poor overlap with stale refs.
