Add a new 'remote.<name>.negotiationInclude' multi-valued config option that
provides default values for --negotiation-include when no
--negotiation-include arguments are specified over the command line. This
is a mirror of how 'remote.<name>.negotiationRestrict' specifies defaults
for the --negotiation-restrict arguments.
Each value is either an exact ref name or a glob pattern whose tips should
always be sent as 'have' lines during negotiation. The config values are
resolved through the same resolve_negotiation_include() codepath as the CLI
options.
This option is additive with the normal negotiation process: the negotiation
algorithm still runs and advertises its own selected commits, but the refs
matching the config are sent unconditionally on top of those heuristically
selected commits.
Similar to the negotiationRestrict config, an empty value resets the value
list to allow ignoring earlier config values, such as those that might be
set in system or global config.

Add a new --negotiation-include option to 'git fetch', which ensures
that certain ref tips are always sent as 'have' lines during fetch
negotiation, regardless of what the negotiation algorithm selects.
This is useful when the repository has a large number of references, so
the normal negotiation algorithm truncates the list. This is especially
important in repositories with long parallel commit histories. For
example, a repo could have a 'dev' branch for development and a
'release' branch for released versions. If the 'dev' branch isn't
selected for negotiation, then it's not a big deal because there are
many in-progress development branches with a shared history. However, if
'release' is not selected for negotiation, then the server may think
that this is the first time the client has asked for that reference,
causing a full download of its parallel commit history (and any extra
data that may be unique to that branch). This is based on a real example
where certain fetches would grow to 60+ GB when a release branch
updated.
This option is a complement to --negotiation-restrict, which reduces the
negotiation ref set to a specific list. In the earlier example, using
--negotiation-restrict to focus the negotiation to 'dev' and 'release'
would avoid those problematic downloads, but would still not allow
advertising potentially-relevant user branches. In this way, the
'include' version solves the problem I mention while allowing
negotiation to pick other references opportunistically. The two options
can also be combined to allow the best of both worlds.
The argument may be an exact ref name or a glob pattern. Non-existent
refs are silently ignored. This behavior is also updated in the ref matching
logic for the related --negotiation-restrict option to match.
The implementation outputs the requested objects as haves before the
negotiator performs its own algorithm to choose the next haves. Use the new
have_sent() interface to signal these have commits were sent before engaging
with the negotiator's next() iterator.
Also add --negotiation-include to 'git pull' passthrough options.

The --negotiation-tip option to 'git fetch' and 'git pull' allows users
to specify that they want to focus negotiation on a small set of
references. This is a _restriction_ on the negotiation set, helping to
focus the negotiation when the ref count is high. However, it doesn't
allow for the ability to opportunistically select references beyond that
list.
This subtle detail that this is a 'maximum set' and not a 'minimum set'
is not immediately clear from the option name. This makes it more
complicated to add a new option that provides the complementary behavior
of a minimum set.
For now, create a new synonym option, --negotiation-restrict, that
behaves identically to --negotiation-tip. Update the documentation to
make it clear that this new name is the preferred option, but we keep
the old name for compatibility. Mark --negotiation-tip as an alias of the
new, preferred option.
Update a few warning messages with the new option, but also make them
translatable with the option name inserted by formatting. At least one
of these messages will be reused later for a new option.

In c39952b92 (fetch: choose a sensible default with --jobs=0 again,
2023-02-20), the `--jobs=0` behavior was (re)introduced, but it went
undocumented. Since this is the same behavior as `git -c fetch.parallel=0
fetch`, which is documented, this change creates symmetry between the two
documentation sections.

Previous commits have set up an infrastructure for `--filter=auto` to
automatically prepare a partial clone filter based on what the server
advertised and the client accepted.
Using that infrastructure, let's now enable the `--filter=auto` option
in `git clone` and `git fetch` by setting `allow_auto_filter` to 1.
Note that these small changes mean that when `git clone --filter=auto`
or `git fetch --filter=auto` are used, "auto" is automatically saved
as the partial clone filter for the server on the client. Therefore
subsequent calls to `git fetch` on the client will automatically use
this "auto" mode even without `--filter=auto`.
Let's also set `allow_auto_filter` to 1 in `transport.c`, as the
transport layer must be able to accept the "auto" filter spec even if
the invoking command hasn't fully parsed it yet.
When an "auto" filter is requested, let's have the "fetch-pack.c" code
in `do_fetch_pack_v2()` compute a filter and send it to the server.
In `do_fetch_pack_v2()` the logic also needs to check for the
"promisor-remote" capability and call `promisor_remote_reply()` to
parse advertised remotes and populate the list of those accepted (and
their filters).

The `--filter=<filter-spec>` option is documented in most commands that
support it except `git fetch`.
Let's fix that and document this option. To ensure consistency across
commands, let's reuse the exact description currently found in
`git clone`.

- Switch the synopsis to a synopsis block which will automatically
format placeholders in italics and keywords in monospace
- Use _<placeholder>_ instead of <placeholder> in the description
- Use `backticks` for keywords and more complex option
descriptions. The new rendering engine will apply synopsis rules to
these spans.

For better searchability, this commit adds a check to ensure that parameters
expressed in the form of `--[no-]parameter` are not used in the
documentation. In the place of such parameters, the documentation should
list two separate parameters: `--parameter` and `--no-parameter`.

We presently use the ".txt" extension for our AsciiDoc files. While not
wrong, most editors do not associate this extension with AsciiDoc,
meaning that contributors don't get automatic editor functionality that
could be useful, such as syntax highlighting and prose linting.
It is much more common to use the ".adoc" extension for AsciiDoc files,
since this helps editors automatically detect files and also allows
various forges to provide rich (HTML-like) rendering. Let's do that
here, renaming all of the files and updating the includes where
relevant. Adjust the various build scripts and makefiles to use the new
extension as well.
Note that this should not result in any user-visible changes to the
documentation.
