Code which split an argv_array call across multiple lines, like:
argv_array_pushl(&args, "one argument",
"another argument", "and more",
NULL);
was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:
strvec_pushl(&args, "one argument",
"another argument", "and more",
NULL);
Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
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 '
s/ARGV_ARRAY/STRVEC/g;
s/argv_array/strvec/g;
'
and then selectively staging files with "git add '[abcdefghjkl]*'".
We'll deal with any indentation/style fallouts separately.

finish_http_pack_request() does multiple tasks, including some
housekeeping on a struct packed_git - (1) closing its index, (2)
removing it from a list, and (3) installing it. These concerns are
independent of fetching a pack through HTTP: they are there only because
(1) the calling code opens the pack's index before deciding to fetch it,
(2) the calling code maintains a list of packfiles that can be fetched,
and (3) the calling code fetches it in order to make use of its objects
in the same process.
In preparation for a subsequent commit, which adds a feature that does
not need any of this housekeeping, remove (1), (2), and (3) from
finish_http_pack_request(). (2) and (3) are now done by a helper
function, and (1) is the responsibility of the caller (in this patch,
done closer to the point where the pack index is opened).

When Git fetches a pack using dumb HTTP, (among other things) it invokes
index-pack on a ".pack.temp" packfile, specifying the filename as an
argument.
A future commit will require the aforementioned invocation of index-pack
to also generate a "keep" file. To use this, we either have to use
index-pack's naming convention (because --keep requires the pack's
filename to end with ".pack") or to pass the pack through stdin. Of the
two, it is simpler to pass the pack through stdin.
Thus, teach http to pass --stdin to index-pack. As a bonus, the code is
now simpler.

We may feed a URL like "cert:///path/to/cert.pem" into the credential
machinery to get the key for a client-side certificate. That
credential has no hostname field, which is about to be disallowed (to
avoid confusion with protocols where a helper _would_ expect a
hostname).
This means as of the next patch, credential helpers won't work for
unlocking certs. Let's fix that by doing two things:
- when we parse a url with an empty host, set the host field to the
empty string (asking only to match stored entries with an empty
host) rather than NULL (asking to match _any_ host).
- when we build a cert:// credential by hand, similarly assign an
empty string
It's the latter that is more likely to impact real users in practice,
since it's what's used for http connections. But we don't have good
infrastructure to test it.
The url-parsing version will help anybody using git-credential in a
script, and is easy to test.

In 93b980e58f (http: use xmalloc with cURL, 2019-08-15), we started to
ask cURL to use `xmalloc()`, and if compiled with nedmalloc, that means
implicitly a different allocator than the system one.
Which means that all of cURL's allocations and releases now _need_ to
use that allocator.
However, the `http_options()` function used `slist_append()` to add any
configured extra HTTP header(s) _before_ asking cURL to use `xmalloc()`,
and `http_cleanup()` would release them _afterwards_, i.e. in the
presence of custom allocators, cURL would attempt to use the wrong
allocator to release the memory.
A naïve attempt at fixing this would move the call to
`curl_global_init()` _before_ the config is parsed (i.e. before that
call to `slist_append()`).
However, that does not work, as we _also_ parse the config setting
`http.sslbackend` and if found, call `curl_global_sslset()` which *must*
be called before `curl_global_init()`, for details see:
https://curl.haxx.se/libcurl/c/curl_global_sslset.html
So let's instead make the config parsing entirely independent from
cURL's data structures. Incidentally, this deletes two more lines than
it introduces, which is nice.

The fread/fwrite-like functions in http.c, namely fread_buffer,
fwrite_buffer, fwrite_null, fwrite_sha1_file all return the
multiplication of the size and number of items they are being given.
Practically speaking, it doesn't matter, because in all contexts where
those functions are used, size is 1.
But those functions being similar to fread and fwrite (the curl API is
designed around being able to use fread and fwrite directly), it might
be preferable to make them behave like fread and fwrite, which, from
the fread/fwrite manual page, is:
On success, fread() and fwrite() return the number of items read
or written. This number equals the number of bytes transferred
only when size is 1. If an error occurs, or the end of the file
is reached, the return value is a short item count (or zero).

our pointer, rather than dealing with magic numbers. This also fixes a
few small shortcomings:
- if we see a line with the right prefix, suffix, and length, i.e.
matching /P pack-.{40}.pack\n/, we'll interpret the middle part as
hex without checking if it could be parsed. This could lead to us
looking at uninitialized garbage in the hash array. In practice this
means we'll just make a garbage request to the server which will
fail, though it's interesting that a malicious server could convince
us to leak 40 bytes of uninitialized stack to them.

The loose object access code in sha1-file.c is some of the oldest in
Git, and could use some modernizing. It mostly uses "unsigned char *"
for object ids, which these days should be "struct object_id".
It also uses the term "sha1_file" in many functions, which is confusing.
The term "loose_objects" is much better. It clearly distinguishes
them from packed objects (which didn't even exist back when the name
"sha1_file" came into being). And it also distinguishes it from the
checksummed-file concept in csum-file.c (which until recently was
actually called "struct sha1file"!).
This patch converts the functions {open,close,map,stat}_sha1_file() into
open_loose_object(), etc, and switches their sha1 arguments for
object_id structs. Similarly, path functions like fill_sha1_path()
become fill_loose_path() and use object_ids.

just drop the "sha1" (and teach it to use object_id).

(and the other callers always use an empty buffer, so they don't care
either way). Let's handle this automatically.

This config value should only be set to "false" if you are in an

no alternative options.
This is only supported in cURL 7.44 or later.
Note: originally, we wanted to call the config setting
`http.schannel.checkRevoke`. This, however, does not work: the `http.*`
