Now that the previous commit removed the possibility that a "struct
remote" will ever have zero url fields, we can drop a number of
redundant checks and untriggerable code paths.

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).

Each of these were checked with
gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE}
to ensure that removing the direct inclusion of the header actually
resulted in that header no longer being included at all (i.e. that
no other header pulled it in transitively).
...except for a few cases where we verified that although the header
was brought in transitively, nothing from it was directly used in
that source file. These cases were:
* builtin/credential-cache.c
* builtin/pull.c
* builtin/send-pack.c

Ever since a64215b6cd ("object.h: stop depending on cache.h; make
cache.h depend on object.h", 2023-02-24), we have a few headers that
could have replaced their include of cache.h with an include of
object.h. Make that change now.
Some C files had to start including cache.h after this change (or some
smaller header it had brought in), because the C files were depending
on things from cache.h but were only formerly implicitly getting
cache.h through one of these headers being modified in this patch.

Commit 70b9c10373 (bundle-uri client: add helper for testing server,
2022-12-22) added a cmd_ls_remote() function which contains "uploadpack"
and "server_options" variables. Neither of these variables is ever
modified after being initialized, so the code to handle non-NULL and
non-empty values is impossible to reach.
While in theory we might add command-line parsing to set these, let's
drop the dead code for now in the name of cleanliness. It's easy enough
to add it back later if need be.
Noticed by Coverity.

Bundle providers may want to distribute that data across multiple CDNs.
This might require a change in the base URI, all the way to the domain
name. If all bundles require an absolute URI in their 'uri' value, then
every push to a CDN would require altering the table of contents to
match the expected domain and exact location within it.
Allow a bundle list to specify a relative URI for the bundles. This URI
is based on where the client received the bundle list. For a list
provided in the 'bundle-uri' protocol v2 command, the Git remote URI is
the base URI. Otherwise, the bundle list was provided from an HTTP URI
not using the Git protocol, and that URI is the base URI. This allows
easier distribution of bundle data.

Add a 'test-tool bundle-uri ls-remote' command. This is a thin wrapper
for issuing protocol v2 "bundle-uri" commands to a server, and to the
parsing routines in bundle-uri.c.
In the "git clone" case we'll have already done the handshake(),
but not here. Add an extra case to check for this handshake in
get_bundle_uri() for ease of use for future callers.

When a bundle provider wants to operate independently from a Git remote,
they want to provide a single, consistent URI that users can use in
their 'git clone --bundle-uri' commands. At this point, the Git client
expects that URI to be a single bundle that can be unbundled and used to
bootstrap the rest of the clone from the Git server. This single bundle
cannot be re-used to assist with future incremental fetches.
To allow for the incremental fetch case, teach Git to understand a
bundle list that could be advertised at an independent bundle URI. Such
a bundle list is likely to be inspected by human readers, even if only
by the bundle provider creating the list. For this reason, we can take
our expected "key=value" pairs and instead format them using Git config
format.
Create bundle_uri_parse_config_format() to parse a file in config format
and convert that into a 'struct bundle_list' filled with its
understanding of the contents.
Be careful to use error_action CONFIG_ERROR_ERROR when calling
git_config_from_file_with_options() because the default action for
git_config_from_file() is to die() on a parsing error. The current
warning isn't particularly helpful if it arises to a user, but it will
be made more verbose at a higher layer later.
Update 'test-tool bundle-uri' to take this config file format as input.
It uses a filename instead of stdin because there is no existing way to
parse a FILE pointer in the config machinery. Using
git_config_from_mem() is overly complicated and more likely to introduce
bugs than this simpler version.

Create a new 'test-tool bundle-uri' test helper. This helper will assist
in testing logic deep in the bundle URI feature.
This change introduces the 'parse-key-values' subcommand, which parses
an input file as a list of lines. These are fed into
bundle_uri_parse_line() to test how we construct a 'struct bundle_list'
from that data. The list is then output to stdout as if the key-value
pairs were a Git config file.
We use an input file instead of stdin because of a future change to
parse in config-file format that works better as an input file.
