Building with NO_CURL is currently broken since imap-send.c uses things
defined in "strbuf.h" wihtout including it.
The inclusion of that header was removed in eea0e59ffb (treewide: remove
unnecessary includes in source files, 2023-12-23), which failed to
notice that "strbuf.h" was transitively included in imap-send.c via
"http.h", but only if USE_CURL_FOR_IMAP_SEND is defined. Add back the
missing include. Note that it was explicitely added in 3307f7dde2
(imap-send: include strbuf.h, 2023-05-17) after a similar breakage in
ba3d1c73da (treewide: remove unnecessary cache.h includes, 2023-02-24) -
see the thread starting at [1].
It can be verified by inspection that this is the only case where a
header we include is dependent on a Makefile knob in the files modified
in eea0e59ffb.

The point of git_die_config() is to let configset users mention the
file/line info for invalid config, like:
if (!git_config_get_int("foo.bar", &value)) {
if (!is_ok(value))
git_die_config("foo.bar");
}
Using it from within a config callback is unnecessary, because we can
simply return an error, at which point the config machinery will mention
the file/line of the offending variable. Worse, using git_die_config()
can actually produce the wrong location when the key is found in
multiple spots. For instance, with config like:
[imap]
host
host = foo
we'll report the line number of the "host = foo" line, but the problem
is on the implicit-bool "host" line.
We can fix it by just returning an error code.

Earlier patches annotating unused parameters in imap-send missed a few
cases in code that is compiled only with NO_OPENSSL. These need to
retain the extra parameters to match the interfaces used when we compile
with openssl support.
Note in the case of socket_perror() that the function declaration and
parts of its code are shared between the two cases, and only the openssl
code looks at "sock". So we can't simply mark the parameter as always
unused. Instead, we can add a noop statement that references it. This is
ugly, but should be portable.

The imap_cmd_cb struct has several fields which are totally unused.
Presumably they did useful things in the upstream isync code from which
this is derived, but they don't in our more limited program. This is
particularly confusing for the "done" callback, which (as of the
previous patch) no longer matches the signature of the adjacent "cont"
callback.
Since we're unlikely to share code with isync going forward, we should
feel free to simplify the code here. Note that "done" is examined but
never set, so we can also drop a little bit of code outside of the
struct definition.

There's a generic callback mechanism for handling plus-continuation of
IMAP commands. It takes the imap_cmd struct itself as an argument. That
seems reasonable, and in a larger imap-using program it might be used.
But in imap-send, we have only one such callback (auth_cram_md5) and it
doesn't use this value, triggering -Wunused-parameter warnings.
We could just mark the parameter as UNUSED. But since this is the only
such function, and because we are not likely to share code with the
upstream isync anymore, we can just simplify the interface to remove
this parameter.

Our caller passes in an imap_server_conf struct, but we ignore it
totally, and instead read the config directly from the global "server"
variable. This works OK, since our sole caller will pass in that same
global variable. But the intent seems to have been to use the passed-in
variable, as otherwise it has no purpose (and many other functions use
the same pattern).
Let's use the passed-in value, which also silences a -Wunused-parameter
warning.
It would be nice if "server" was not a global here, as we could avoid
making similar mistakes. But changing that would be a larger refactor,
as it must be accessed as a global in a few spots (e.g., filling it in
with the config callback).

Plumb "struct key_value_info" through all code paths that end in
die_bad_number(), which lets us remove the helper functions that read
analogous values from "struct config_reader". As a result, nothing reads
config_reader.config_kvi any more, so remove that too.
In config.c, this requires changing the signature of
git_configset_get_value() to 'return' "kvi" in an out parameter so that
git_configset_get_<type>() can pass it to git_config_<type>(). Only
numeric types will use "kvi", so for non-numeric types (e.g.
git_configset_get_string()), pass NULL to indicate that the out
parameter isn't needed.
Outside of config.c, config callbacks now need to pass "ctx->kvi" to any
of the git_config_<type>() functions that parse a config string into a
number type. Included is a .cocci patch to make that refactor.
The only exceptional case is builtin/config.c, where git_config_<type>()
is called outside of a config callback (namely, on user-provided input),
so config source information has never been available. In this case,
die_bad_number() defaults to a generic, but perfectly descriptive
message. Let's provide a safe, non-NULL for "kvi" anyway, but make sure
not to change the message.

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.

As discussed in 644de29e22 (http: drop support for curl < 7.19.4,
2021-07-30) checking against LIBCURL_VERSION_NUM isn't as reliable as
checking specific symbols present in curl, as some distros have been
known to backport features.
However, while some of the curl_easy_setopt() arguments we rely on are
macros, others are enum, and we can't assume that those that are
macros won't change into enums in the future.
So we're still going to have to check LIBCURL_VERSION_NUM, but by
doing that in one central place and using a macro definition of our
own, anyone who's backporting features can define it themselves, and
thus have access to more modern curl features that they backported,
even if they didn't bump the LIBCURL_VERSION_NUM.
More importantly, as shown in a preceding commit doing these version
checks makes for hard to read and possibly buggy code, as shown by the
bug fixed there where we were conflating base 10 for base 16 when
comparing the version.
By doing them all in one place we'll hopefully reduce the chances of
such future mistakes, furthermore it now becomes easier to see at a
glance what the oldest supported version is, which makes it easier to
reason about any future deprecation similar to the recent
e48a623dea (Merge branch 'ab/http-drop-old-curl', 2021-08-24).

Support for ancient versions of cURL library (pre 7.19.4) has been

In the last commit we dropped support for curl < 7.11.1, let's
continue that and drop support for versions older than 7.16.0. This
allows us to get rid of some now-obsolete #ifdefs.
Choosing 7.16.0 is a somewhat arbitrary cutoff:
1. It came out in October of 2006, almost 15 years ago.
Besides being a nice round number, around 10 years is
a common end-of-life support period, even for conservative
distributions.
2. That version introduced the curl_multi interface, which
gives us a lot of bang for the buck in removing #ifdefs
RHEL 5 came with curl 7.15.5[1] (released in August 2006). RHEL 5's
extended life cycle program ended on 2020-11-30[1]. RHEL 6 comes with
curl 7.19.7 (released in November 2009), and RHEL 7 comes with
7.29.0 (released in February 2013).

We eventually want to drop the argv_array name and just use strvec

Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts remaining files from the first half of the alphabet,
to keep the diff to a manageable size.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '
