A previous commit allowed a server to pass additional fields through
the "promisor-remote" protocol capability after the "name" and "url"
fields, specifically the "partialCloneFilter" and "token" fields.
Let's make it possible for a client to check if these fields match
what it expects before accepting a promisor remote.
We allow this by introducing a new "promisor.checkFields"
configuration variable. It should contain a comma or space separated
list of fields that will be checked.
By limiting the protocol to specific well-defined fields, we ensure
both server and client have a shared understanding of field
semantics and usage.

For now the "promisor-remote" protocol capability can only pass "name"
and "url" information from a server to a client in the form
"name=<remote_name>,url=<remote_url>".
To allow clients to make more informed decisions about which promisor
remotes they accept, let's make it possible to pass more information
by introducing a new "promisor.sendFields" configuration variable.
On the server side, information about a remote `foo` is stored in
configuration variables named `remote.foo.<variable-name>`. To make
it clearer and simpler, we use `field` and `field name` like this:
* `field name` refers to the <variable-name> part of such a
configuration variable, and
* `field` refers to both the `field name` and the value of such a
configuration variable.
The "promisor.sendFields" configuration variable should contain a
comma or space separated list of field names that will be looked up
in the configuration of the remote on the server to find the values
that will be passed to the client.
Only a set of predefined field names are allowed. The only field
names in this set are "partialCloneFilter" and "token". The
"partialCloneFilter" field name specifies the filter definition used
by the promisor remote, and the "token" field name can provide an
authentication credential for accessing it.
For example, if "promisor.sendFields" is set to "partialCloneFilter",
and the server has the "remote.foo.partialCloneFilter" config
variable set to a value, then that value will be passed in the
"partialCloneFilter" field in the form "partialCloneFilter=<value>"
after the "name" and "url" fields.
A following commit will allow the client to use the information to
decide if it accepts the remote or not. For now the client doesn't do
anything with the additional information it receives.

As part of the ongoing effort to consolidate reference handling,
introduce a new `exists` subcommand. This command provides the same
functionality and exit-code behavior as `git show-ref --exists`, serving
as its modern replacement.
The logic for `show-ref --exists` is minimal. Rather than creating a
shared helper function which would be overkill for ~20 lines of code,
its implementation is intentionally duplicated here. This contrasts with
`git refs list`, where sharing the larger implementation of
`for-each-ref` was necessary.
Documentation for the new subcommand is also added to the `git-refs(1)`
man page.

Our codebase uses a lot of bit field variables, generally to mark
boolean type variables. While there is a formatting rule in the
'.clang-format', there is no guideline specified in the
'CodingGuidelines'.
Since the '.clang-format' is not yet enforced, let's also add a
guideline with the same rule as mentioned in the '.clang-format', which
is to not use any spaces around the colon, like so:
unsigned my_field:1;
unsigned other_field:1;
unsigned field_with_longer_name:1;
This would allow us not to modify the clang-format file, and more
importantly, discourage people from doing ugly alignment with spaces,
i.e.
unsigned my_field : 1;
unsigned other_field : 1;
unsigned field_with_longer_name : 1;

When "core.commentString" is set to "auto" then "git commit" will
automatically select the comment character ensuring that it is not the
first character on any of the lines in the commit message. This was
introduced by commit 84c9dc2c5a (commit: allow core.commentChar=auto
for character auto selection, 2014-05-17). The motivation seems to be
to avoid commenting out lines from the existing message when amending
a commit that was created with a message from a file.
Unfortunately this feature does not work with:
* commit message templates that contain comments.
* prepare-commit-msg hooks that introduce comments.
* "git commit --cleanup=strip --edit -F <file>" which means that it
is incompatible with
- the "fixup" and "squash" commands of "git rebase -i" as the
comments added by those commands are then treated as part of
the commit message.
- the conflict comments added to the commit message by "git
cherry-pick", "git rebase" etc. as these comments are then
treated as part of the commit message.
It is also ignored by "git notes" when amending a note.
The issues with comments coming from a template, hook or file are a
consequence of the design of this feature and are therefore hard to
fix.
As the costs of this feature outweigh the benefits, deprecate it and
remove it in Git 3.0. If someone comes up with some patches that fix
all the issues in a maintainable way then I'd be happy to see this
change reverted.
The next commits will add a warning and some advice for users on how
they can update their config settings.

The compatibility object format is only implemented for loose objects,
not packed objects, so anyone attempting to push or fetch data into a
repository with this option will likely not see it work as expected. In
addition, the underlying storage of loose object mapping is likely to
change because the current format is inefficient and does not handle
important mapping information such as that of submodules.
It would have been preferable to initially document that this was not
yet ready for prime time, but we did not do so. We hinted at the fact
that this functionality is incomplete in the description, but did not
say so explicitly. Let's do so now: indicate that this feature is
incomplete and subject to change and that the option is not designed to
be used by end users.

Using one of the start_delayed_*() functions, clients of the progress
API can request that a progress meter is only shown after some time.
To do that, the implementation intends to count down the number of
seconds stored in struct progress by observing flag progress_update,
which the timer interrupt handler sets when a second has elapsed. This
works during the first second of the delay. But the code forgets to
reset the flag to zero, so that subsequent calls of display_progress()
think that another second has elapsed and decrease the count again
until zero is reached. Due to the frequency of the calls, this happens
without an observable delay in practice, so that the effective delay is
always just one second.
This bug has been with us since the inception of the feature. Despite
having been touched on various occasions, such as 8aade107dd
(progress: simplify "delayed" progress API), 9c5951cacf (progress:
drop delay-threshold code), and 44a4693bfc (progress: create
GIT_PROGRESS_DELAY), the short delay went unnoticed.
Copy the flag state into a local variable and reset the global flag
right away so that we can detect the next clock tick correctly.
Since we have not had any complaints that the delay of one second is
too short nor that GIT_PROGRESS_DELAY is ignored, people seem to be
comfortable with the status quo. Therefore, set the default to 1 to
keep the current behavior.
