Make the mergetool used with "meld" backend behave similarly to "vimdiff" by
telling it to auto-merge non-conflicting parts and highlight the conflicting
parts when `mergetool.meld.useAutoMerge` is configured with `true`, or `auto`
for detecting the `--auto-merge` option automatically.

Enable ref-filter to process multiple merged and no-merged filters, and
extend functionality to git branch, git tag and git for-each-ref. This
provides an easy way to check for branches that are "graduation
candidates:"
$ git branch --no-merged master --merged next
If passed more than one merged (or more than one no-merged) filter, refs
must be reachable from any one of the merged commits, and reachable from
none of the no-merged commits.

The options indicate user intent for the whole fetch operation, and

"git status" has trouble showing where it came from by interpreting
reflog entries that recordcertain events, e.g. "checkout @{u}", and
gives a hard/fatal error. Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error to allow "status" show its

Currently, when index-pack resolves deltas, it does not split up delta
trees into threads: each delta base root (an object that is not a
REF_DELTA or OFS_DELTA) can go into its own thread, but all deltas on
that root (direct or indirect) are processed in the same thread.
This is a problem when a repository contains a large text file (thus,
delta-able) that is modified many times - delta resolution time during
fetching is dominated by processing the deltas corresponding to that
text file.
This patch contains a solution to that. When cloning using
git -c core.deltabasecachelimit=1g clone \
https://fuchsia.googlesource.com/third_party/vulkan-cts
on my laptop, clone time improved from 3m2s to 2m5s (using 3 threads,
which is the default).
The solution is to have a global work stack. This stack contains delta
bases (objects, whether appearing directly in the packfile or generated
by delta resolution, that themselves have delta children) that need to
be processed; whenever a thread needs work, it peeks at the top of the
stack and processes its next unprocessed child. If a thread finds the
stack empty, it will look for more delta base roots to push on the stack
instead.
The main weakness of having a global work stack is that more time is
spent in the mutex, but profiling has shown that most time is spent in
the resolution of the deltas themselves, so this shouldn't be an issue
in practice. In any case, experimentation (as described in the clone
command above) shows that this patch is a net improvement.

When formatting a patch series over `origin..HEAD`, one would expect
that range to be used as the current-series-range when computing a
range-diff between the previous and current versions of a patch series.
However, infer_range_diff_ranges() ignores `origin..HEAD` when
--range-diff=<prev> specifies a single revision rather than a range, and
instead unexpectedly computes the current-series-range based upon
<prev>. Address this anomaly by unconditionally using `origin..HEAD` as
the current-series-range regardless of <prev> as long as `origin` is
known, and only fall back to basing current-series-range on <prev> when
`origin` is not known.

To compute and show an interdiff, show_interdiff() needs only the two
OID's to compare and a diffopts, yet it expects callers to supply an
entire rev_info. The demand for rev_info is not only overkill, but also
places unnecessary burden on potential future callers which might not
otherwise have a rev_info at hand. Address this by tightening its
signature to require only the items it needs instead of a full rev_info.

show_interdiff() is a relatively small function and not likely to grow
larger or more complicated. Rather than dedicating an entire source file
to it, relocate it to diff-lib.c which houses other "take two things and
compare them" functions meant to be re-used but not so low-level as to
reside in the core diff implementation.

We have had parallel implementations of "add -i/-p" since 2.25 and
have been using them from various codepaths since 2.26 days, but
never made the built-in version the default.
We have found and fixed a handful of corner case bugs in the
built-in version, and it may be a good time to start switching over
the user base from the scripted version to the built-in version.
Let's enable the built-in version for those who opt into the
feature.experimental guinea-pig program to give wider exposure.

Like `git switch` and `git checkout`, `git worktree add` can check out a
branch or set up a detached HEAD. However, unlike those other commands,
`git worktree add` does not understand -d as shorthand for --detach,
which may confound users accustomed to using -d for this purpose.
Address this shortcoming by teaching `add` to recognize -d for --detach,
thus bringing it in line with the other commands.

map_refspec() either returns the passed in ref string or a detached
strbuf. This makes it hard for callers to release the possibly
allocated memory, and set_refspecs() consequently leaks it.
Let map_refspec() append any refspecs directly and release its own
strbufs after use. Rename it to refspec_append_mapped() and don't
return anything to reflect its increased responsibility.
set_refspecs() also leaks its strbufs. Do the same here and directly
call refspec_append() in each if branch instead of holding onto a
detached strbuf, then dispose of the allocated memory after use. We
need to add an else branch for the final call because all the other
conditional branches already add their formatted refspec now.
setup_push_upstream() and setup_push_current() forgot to release their
strbufs as well; plug these leaks, too, while at it.
None of these leaks were likely to impact users, because the number
and sizes of refspecs are usually small and the allocations are only
done once per program run. Clean them up nevertheless, as another
step on the long road towards zero memory leaks.

When fetching recursively with submodules, for each ref in the
superproject, we call check_for_new_submodule_commits() which collects all
the objects that have to be checked for submodule changes on
calculate_changed_submodule_paths(). On the first call, it also collects all
the existing refs for excluding them from the scan.
calculate_changed_submodule_paths() creates an argument array with all the
collected new objects, followed by --not and all the old objects. This argv
is passed to setup_revisions, which parses each argument, converts it back
to an oid and resolves the object. The parsing itself also does redundant
work, because it is treated like user input, while in fact it is a full
oid. So it needlessly attempts to look it up as ref (checks if it has ^, ~
etc.), checks if it is a file name etc.
For a repository with many refs, all of this is expensive. But if the fetch
in the superproject did not update the ref (i.e. the objects that are
required to exist in the submodule did not change), there is no need to
include it in the list.
Before commit be76c212 (fetch: ensure submodule objects fetched,
2018-12-06), submodule reference changes were only detected for refs that
were changed, but not for new refs. This commit covered also this case, but
what it did was to just include every ref.
This change should reduce the number of scanned refs by about half (except
the case of a no-op fetch, which will not scan any ref), because all the
existing refs will still be listed after --not.
The regression was reported here:

When a user checks out the upstream branch of HEAD, the upstream branch
not being a local branch, and then runs "git status", like this:
git clone $URL client
cd client
git checkout @{u}
git status
no status is printed, but instead an error message:
fatal: HEAD does not point to a branch
(This error message when running "git branch" persists even after
checking out other things - it only stops after checking out a branch.)
This is because "git status" reads the reflog when determining the "HEAD
detached" message, and thus attempts to DWIM "@{u}", but that doesn't
work because HEAD no longer points to a branch.
Therefore, when calculating the status of a worktree, tolerate dangling
marks. This is done by adding an additional parameter to
dwim_ref() and repo_dwim_ref().

887952b8c6 ("fetch: optionally allow disabling FETCH_HEAD update",
2020-08-18) introduced the ability to disable writing to FETCH_HEAD
during fetch, but did not suppress the "<source> -> FETCH_HEAD" message
when this ability is used. This message is misleading in this case,
because FETCH_HEAD is not written. Also, because "fetch" is used to
lazy-fetch missing objects in a partial clone, this significantly
clutters up the output in that case since the objects to be fetched are
potentially numerous.
Therefore, suppress this message when --no-write-fetch-head is passed
(but not when --dry-run is set).

The intention of `git init --separate-work-dir=<path>` is to move the
.git/ directory to a location outside of the main worktree. When used
within a linked worktree, however, rather than moving the .git/
directory as intended, it instead incorrectly moves the worktree's
.git/worktrees/<id> directory to <path>, thus disconnecting the linked
worktree from its parent repository and breaking the worktree in the
process since its local .git file no longer points at a location at
which it can find the object database. Fix this broken behavior.
An intentional side-effect of this change is that it also closes a
loophole not caught by ccf236a23a (init: disallow --separate-git-dir
with bare repository, 2020-08-09) in which the check to prevent
--separate-git-dir being used in conjunction with a bare repository was
unable to detect the invalid combination when invoked from within a
linked worktree. Therefore, add a test to verify that this loophole is
closed, as well.

A linked worktree's .git file is a "gitfile" pointing at the
.git/worktrees/<id> directory within the repository. When `git init
--separate-git-dir=<path>` is used on an existing repository to relocate
the repository's .git/ directory to a different location, it neglects to
update the .git files of linked worktrees, thus breaking the worktrees
by making it impossible for them to locate the repository. Fix this by
teaching --separate-git-dir to repair the .git file of each linked
worktree to point at the new repository location.

The .git/worktrees/<id>/gitdir file points at the location of a linked
worktree's .git file. Its content must be of the form
/path/to/worktree/.git (from which the location of the worktree itself
can be derived by stripping the "/.git" suffix). If the gitdir file is
deleted or becomes corrupted or outdated, then Git will be unable to
find the linked worktree. An easy way for the gitdir file to become
outdated is for the user to move the worktree manually (without using
"git worktree move"). Although it is possible to manually update the
gitdir file to reflect the new linked worktree location, doing so
requires a level of knowledge about worktree internals beyond what a
user should be expected to know offhand.
Therefore, teach "git worktree repair" how to repair broken or outdated
.git/worktrees/<id>/gitdir files automatically. (For this to work, the
command must either be invoked from within the worktree whose gitdir
file requires repair, or from within the main or any linked worktree by
providing the path of the broken worktree as an argument to "git
worktree repair".)
