Add new service (git-upload-archive) support in remote-curl, so we can
support remote archive over HTTP/HTTPS protocols. Differences between
git-upload-archive and other services:
1. The git-archive program does not expect to see protocol version and
capabilities when connecting to remote-helper, so do not send them
in remote-curl for the git-upload-archive service.
2. We need to detect protocol version by calling discover_refs().
Fallback to use the git-upload-pack service (which, like
git-upload-archive, is a read-only operation) to discover protocol
version.

The reftable format encodes the hash function used by the repository
inside of its tables. The reftable backend thus needs to be initialized
with the correct hash function right from the start, or otherwise we may
end up writing tables with the wrong hash function. But git-clone(1)
initializes the reference database before learning about the hash
function used by the remote repository, which has never been a problem
with the reffiles backend.
To fix this, we'll have to change git-clone(1) to be more careful and
only create the reference backend once it learned about the remote hash
function. This creates a problem for git-remote-curl(1), which will then
be spawned at a time where the repository is not yet fully-initialized.
Consequentially, git-remote-curl(1) will fail to detect the repository,
which eventually causes it to error out once it is asked to fetch remote
objects.
We can address this issue by trying to re-discover the Git repository in
case none was detected at startup time. With this change, the clone will
look as following:
1. git-clone(1) sets up the initial repository, excluding the
reference database.
2. git-clone(1) spawns git-remote-curl(1), which will be unable to
detect the repository due to a missing "HEAD".
3. git-clone(1) asks git-remote-curl(1) to list remote references.
This works just fine as this step does not require a local
repository
4. git-clone(1) creates the reference database as it has now learned
about the hash function.
5. git-clone(1) asks git-remote-curl(1) to fetch the remote packfile.
The latter notices that it doesn't have a repository available, but
it now knows to try and re-discover it.
If the re-discovery succeeds in the last step we can continue with the
clone.

hex2chr() takes care not to run over the end of a NUL-terminated string.
It's used in packet_length(), but both callers of that function pass a
four-byte buffer, making NUL-checks unnecessary. packet_length() could
accidentally be used with a pointer to a buffer of unknown size at new
call-sites, though, and the compiler wouldn't complain.
Add a size parameter plus check, and remove the NUL-checks by calling
hexval() directly. This trades three NUL checks against one size check
and the ability to report the use of a short buffer at runtime.
If any of the four bytes is NUL or -- more generally -- not a
hexadecimal digit, then packet_length() still returns a negative value.

There's code in git_connect() that checks whether we are doing a push
with protocol_v2, and if so, drops us to protocol_v0 (since we know
how to do v2 only for fetches). But it misses some corner cases:
1. it checks the "prog" variable, which is actually the path to
receive-pack on the remote side. By default this is just
"git-receive-pack", but it could be an arbitrary string (like
"/path/to/git receive-pack", etc). We'd accidentally stay in v2
mode in this case.
2. besides "receive-pack" and "upload-pack", there's one other value
we'd expect: "upload-archive" for handling "git archive --remote".
Like receive-pack, this doesn't understand v2, and should use the
v0 protocol.
In practice, neither of these causes bugs in the real world so far. We
do send a "we understand v2" probe to the server, but since no server
implements v2 for anything but upload-pack, it's simply ignored. But
this would eventually become a problem if we do implement v2 for those
endpoints, as older clients would falsely claim to understand it,
leading to a server response they can't parse.
We can fix (1) by passing in both the program path and the "name" of the
operation. I treat the name as a string here, because that's the pattern
set in transport_connect(), which is one of our callers (we were simply
throwing away the "name" value there before).
We can fix (2) by allowing only known-v2 protocols ("upload-pack"),
rather than blocking unknown ones ("receive-pack" and "upload-archive").
That will mean whoever eventually implements v2 push will have to adjust
this list, but that's reasonable. We'll do the safe, conservative thing
(sticking to v0) by default, and anybody working on v2 will quickly
realize this spot needs to be updated.
The new tests cover the receive-pack and upload-archive cases above, and
re-confirm that we allow v2 with an arbitrary "--upload-pack" path (that
already worked before this patch, of course, but it would be an easy
thing to break if we flipped the allow/block logic without also handling
"name" separately).
Here are a few miscellaneous implementation notes, since I had to do a
little head-scratching to understand who calls what:
- transport_connect() is called only for git-upload-archive. For
non-http git remotes, that resolves to the virtual connect_git()
function (which then calls git_connect(); confused yet?). So
plumbing through "name" in connect_git() covers that.
- for regular fetches and pushes, callers use higher-level functions
like transport_fetch_refs(). For non-http git remotes, that means
calling git_connect() under the hood via connect_setup(). And that
uses the "for_push" flag to decide which name to use.
- likewise, plumbing like fetch-pack and send-pack may call
git_connect() directly; they each know which name to use.
- for remote helpers (including http), we already have separate
parameters for "name" and "exec" (another name for "prog"). In
process_connect_service(), we feed the "name" to the helper via
"connect" or "stateless-connect" directives.
There's also a "servpath" option, which can be used to tell the
helper about the "exec" path. But no helpers we implement support
it! For http it would be useless anyway (no reasonable server
implementation will allow you to send a shell command to run the
server). In theory it would be useful for more obscure helpers like
remote-ext, but even there it is not implemented.
It's tempting to get rid of it simply to reduce confusion, but we
have publicly documented it since it was added in fa8c097cc9
(Support remote helpers implementing smart transports, 2009-12-09),
so it's possible some helper in the wild is using it.
- So for v2, helpers (again, including http) are mainly used via
stateless-connect, driven by the main program. But they do still
need to decide whether to do a v2 probe. And so there's similar
logic in remote-curl.c's discover_refs() that looks for
"git-receive-pack". But it's not buggy in the same way. Since it
doesn't support servpath, it is always dealing with a "service"
string like "git-receive-pack". And since it doesn't support
straight "connect", it can't be used for "upload-archive".
So we could leave that spot alone. But I've updated it here to match
the logic we're changing in connect_git(). That seems like the least
confusing thing for somebody who has to touch both of these spots
later (say, to add v2 push support). I didn't add a new test to make
sure this doesn't break anything; we already have several tests (in
t5551 and elsewhere) that make sure we are using v2 over http.

The IOCTLFUNCTION option has been deprecated, and generates a compiler
warning in recent versions of curl. We can switch to using SEEKFUNCTION
instead. It was added in 2008 via curl 7.18.0; our INSTALL file already
indicates we require at least curl 7.19.4.
But there's one catch: curl says we should use CURL_SEEKFUNC_{OK,FAIL},
and those didn't arrive until 7.19.5. One workaround would be to use a
bare 0/1 here (or define our own macros). But let's just bump the
minimum required version to 7.19.5. That version is only a minor version
bump from our existing requirement, and is only a 2 month time bump for
versions that are almost 13 years old. So it's not likely that anybody
cares about the distinction.
Switching means we have to rewrite the ioctl functions into seek
functions. In some ways they are simpler (seeking is the only
operation), but in some ways more complex (the ioctl allowed only a full
rewind, but now we can seek to arbitrary offsets).
Curl will only ever use SEEK_SET (per their documentation), so I didn't
bother implementing anything else, since it would naturally be
completely untested. This seems unlikely to change, but I added an
assertion just in case.
Likewise, I doubt curl will ever try to seek outside of the buffer sizes
we've told it, but I erred on the defensive side here, rather than do an
out-of-bounds read.

Migrate those run-command API users that assign directly to the "argv"

In these cases it did not make sense to further refactor these
callers, e.g. daemon.c could be made to construct the arguments closer
to handle(), but that would require moving the construction from its
cmd_main() and pass "argv" through two intermediate functions.
It would be possible for a change like this to introduce a regression

cp.argv = argv;
argv[1] = "foo";
And changed the code, as is being done here, to:
strvec_pushv(&cp.args, argv);

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

We could solve these compilation problems with more #ifdefs,
but it's not worth the trouble. Version 7.11.1 came out in
March of 2004, over 17 years ago. Let's declare that too old
and drop any existing ifdefs that go further back. One
obvious benefit is that we'll have fewer conditional bits
cluttering the code.

patch was sent, it included an oversight where the error messages
referenced "stateless separator", the work-in-progress name, over
"response end", the final name chosen.
Correct these error messages by having them correctly reference
a "response end" packet.

The remote-https process needs to update it's own instance of
`the_repository' when it sees an HTTP(S) remote is using sha256.
Without this, parse_oid_hex() fails to handle sha256 OIDs when
it's eventually called by parse_fetch().
Tested with:
git clone https://yhbt.net/sha256test.git
GIT_SMART_HTTP=0 git clone https://yhbt.net/sha256test.git
(plain http:// also works)
Cloning the URL via git:// required no changes

The previous commit added the necessary machinery to implement the
"--force-if-includes" protection, when "--force-with-lease" is used
without giving exact object the remote still ought to have. Surface
the feature by adding a command line option and a configuration
variable to enable it.
- Add a flag: "TRANSPORT_PUSH_FORCE_IF_INCLUDES" to indicate that the
new option was passed from the command line of via configuration
settings; update command line and configuration parsers to set the
new flag accordingly.
- Introduce a new configuration option "push.useForceIfIncludes", which
is equivalent to setting "--force-if-includes" in the command line.
- Update "remote-curl" to recognize and pass this option to "send-pack"
when enabled.
- Update "advise" to catch the reject reason "REJECT_REF_NEEDS_UPDATE",
set when the ref status is "REF_STATUS_REJECT_REMOTE_UPDATED" and
(optionally) print a help message when the push fails.
- The new option is a "no-op" in the following scenarios:
* When used without "--force-with-lease".
* When used with "--force-with-lease", and if the expected commit
on the remote side is specified as an argument.

Updates to on-demand fetching code in lazily cloned repositories.
* jt/lazy-fetch:
fetch: no FETCH_HEAD display if --no-write-fetch-head
fetch-pack: remove no_dependents code
promisor-remote: lazy-fetch objects in subprocess
fetch-pack: do not lazy-fetch during ref iteration
fetch: only populate existing_refs if needed
fetch: avoid reading submodule config until needed
fetch: allow refspecs specified through stdin
negotiator/noop: add noop fetch negotiator
88e2f9ed8e ("introduce fetch-object: fetch one promisor object",
2017-12-05) plumbed through the from_promisor parameter but did
not document it everywhere it appeared. Add the documentation.
(It also plumbed through the no_dependents parameter, but I have left
that alone because it is being removed in a commit under review [1].)

Now that Git has switched to using a subprocess to lazy-fetch missing
objects, remove the no_dependents code as it is no longer used.

The argv_array API is useful for not just managing argv but any
"vector" (NULL-terminated array) of strings, and has seen adoption
to a certain degree. It has been renamed to "strvec" to reduce the
barrier to adoption.
* jk/strvec:
strvec: rename struct fields
strvec: drop argv_array compatibility layer
strvec: update documention to avoid argv_array
strvec: fix indentation in renamed calls
strvec: convert remaining callers away from argv_array name
strvec: convert more callers away from argv_array name
strvec: convert builtin/ callers away from argv_array name
quote: rename sq_dequote_to_argv_array to mention strvec
strvec: rename files from argv-array to strvec
argv-array: rename to strvec
argv-array: use size_t for count and alloc
The "argc" and "argv" names made sense when the struct was argv_array,
but now they're just confusing. Let's rename them to "nr" (which we use
for counts elsewhere) and "v" (which is rather terse, but reads well
when combined with typical variable names like "args.v").
Note that we have to update all of the callers immediately. Playing
tricks with the preprocessor is hard here, because we wouldn't want to
rewrite unrelated tokens.
