The experimental 'git history' command has been taught a new 'squash'
subcommand to fold a range of commits into a single commit, with any
descendants replayed on top.

Add a built-in userdiff driver for the Swift programming language so that
diff hunk headers and word diffs work out of the box for ".swift" files.
The funcname pattern is built for Swift's own declaration grammar: an
optional run of attributes ("@objc", "@available(iOS 13, *)", ...),
followed by an optional run of lowercase modifiers ("public", "static",
"final", ...), followed by a declaration keyword (func, class, struct,
enum, protocol, extension, actor, init, deinit, subscript). The keyword
is followed by a boundary that allows whitespace, "(" (init/subscript),
"?" or "!" (failable init), or "<" (generics), while still acting as a
word boundary so e.g. "initialize(" does not match.
The word regex recognizes Swift identifiers, hexadecimal, octal, binary,
integer and floating-point literals, and the language's operators.

The object database enumeration interface odb_for_each_object() has
been taught to accept object filters, allowing the underlying backends
to optimize the traversal by using reachability bitmaps when
available. 'git cat-file --batch-all-objects' has been updated to use
this generic interface, simplifying its code and avoiding direct
access to ODB backend internals.

submodule--helper: accept '-i' shorthand for update --init
A few memory problems in the Rust interface to C hash functions have
been corrected. The 'Clone' implementation of 'CryptoHasher' now
properly initializes the context before cloning, and its 'Drop'
implementation now discards the context to prevent leaks.
* bc/rust-hash-cleanups:
rust: discard hash context when finished

The stream-based object signature verification path has been
corrected to avoid double-closing the stream on read errors.
* ps/odb-stream-double-close-fix:
object-file: fix closing object stream twice
The rebase post-rewrite notes-copying logic has been corrected. When
a commit is dropped during rebase (e.g., because its changes are
already upstream), it is no longer recorded as rewritten, preventing
its notes from being copied to an unrelated commit.

refactored to take a repository parameter, allowing the removal of the
implicit dependency on the global 'the_repository' variable in
'copy.c'.
* ps/copy-wo-the-repository:
copy: drop dependency on `the_repository`
The enumeration of untracked and ignored files in 'git status' has
been optimized by avoiding quadratic complexity insertion into string
lists, reducing the construction cost from O(n^2) to O(n log n).
* sc/wt-status-avoid-quadratic-insertion:
wt-status: avoid repeated insertion for untracked paths
The dependency on the global 'the_repository' variable in the
'refspec.c' API has been removed by passing the hash algorithm
explicitly to refspec-parsing functions and storing it in 'struct
refspec'.
* ps/refspec-wo-the-repository:
refspec: stop depending on `the_repository`
refspec: let callers pass in hash algorithm when parsing items
refspec: group related structures and functions
Move the global 'has_symlinks' configuration into the

The ce_mode_from_stat() function is a performance-critical static
inline helper in 'read-cache.h'. As we migrate configuration
variables into the repository struct, this helper needs access
to the repository context.
Update the signature of ce_mode_from_stat() to take a 'struct
repository *' parameter, and update all callers to pass the
appropriate repository instance.
To prepare for the overhead of replacing cheap global variable
accesses with getter functions, the boolean expressions are
reordered to evaluate 'S_ISREG(mode)' first.
While at it, add a comment for ce_mode_from_stat().

By default "git history squash" reuses the oldest commit's message, or
the replacement body from an amend! commit targeting it. When
--reedit-message is given it only reopened that selected message, so the
messages of the other commits in the range were lost.
Gather the message of every commit in the range and build the same editor
template that "git rebase -i --autosquash" shows for a squash, reusing
add_squash_combination_header(), add_squash_message_header() and
squash_subject_comment_len(). Feed the range through
todo_list_rearrange_squash() so that each fixup!, squash! or amend! is
grouped under the commit it targets rather than shown in commit order,
exactly as autosquash would arrange them.
Only the message text differs, the changes are always folded in. A fixup!
message is commented out in full under a "will be skipped" header, a
squash! keeps its body with only the marker subject commented, and an
amend! replaces its target's message unless a squash! already folded into
that target, in which case it behaves like a squash!.

When "git rebase -i" squashes commits it builds an editor template with a
"This is a combination of N commits." banner, a "This is the 1st/Nth
commit message:" header above each kept message (or a "will be skipped"
header for a dropped one), and a commented-out subject for any fixup!,
squash! or amend! commit. The banner, the headers and the
subject-commenting all live in static helpers in sequencer.c wired to the
rebase state, so no other command can present a squash the same way.
Pull the three pieces out into add_squash_combination_header(),
add_squash_message_header() (which takes a flag for the "will be skipped"
variant) and squash_subject_comment_len(), and use them from
update_squash_messages() and append_squash_message(). Also move the
todo_item_flags enum to the header, so a caller reading the output of
todo_list_rearrange_squash() can tell an amend! (TODO_REPLACE_FIXUP_MSG)
from a plain fixup!. A later change reuses all of this to give "git
history squash --reedit-message" the same template.
No change in behavior.

Folding a series of commits into one required either an interactive
rebase where each commit after the first was hand-edited to "fixup", or
a "git reset --soft" to the merge base followed by "git commit --amend".
Add "git history squash <revision-range>" to do this directly. It folds
every commit in the range into the oldest one, keeping that commit's
authorship and taking the tree of the newest commit, then replays the
commits above the range on top. The squashed message comes from the
oldest commit by default, or from the body of the last amend! commit
targeting it. An editor opens with the selected message when
--reedit-message is given. A fixup!, squash! or amend! commit is refused
unless the commit it targets is also in the range, so the fold does not
silently absorb a marker meant for a commit outside it. The check runs
the range through todo_list_rearrange_squash(), which leaves such a
marker as a plain pick. Markers whose target is in the range fold in as
usual. As an exception, a range made up entirely of markers for one
target is combined anyway, taking its message from the last amend! if
there is one, so a batch of fixups for the same commit can be collapsed.
The range is read like the arguments to "git rev-list", so several
revisions such as "HEAD~3..HEAD ^topic" may be given, and rev-list
options are accepted too. As "git replay" does, the walk options the fold
relies on are forced after setup_revisions() and a warning is printed if
an option changed them, so the first commit returned is the range's
oldest and its parent is the base regardless of what the user passed
(including after a "--"). A merge inside the range is folded when its
other parent is reachable from the base, otherwise the range has more
than one base and is rejected. By default the command also refuses when a
ref points at a commit that the fold would discard. Use --update-refs=head
to rewrite only the current branch instead.

When a bisection finishes, "git bisect" reports the first bad commit
but leaves the session active until "git bisect reset" is run by hand.
Add a "--reset-when-found[=<where>]" option, accepted by both "git
bisect start" and "git bisect run", that resets as soon as the first
bad commit is found. The "original" value returns to the commit checked
out before "git bisect start", while "found" leaves the first bad commit
checked out; omitting the value defaults to "original".
Persist the selected target in a BISECT_RESET_WHEN_FOUND state file
and perform the reset quietly.
For "git bisect run", defer the reset until after the captured output
is printed and BISECT_RUN is closed. This lets cleanup remove the file
on systems that cannot unlink an open file.

When we allocate a context but then abandon it, we never discard it,
which means that the underlying crypto library context may leak. This
doesn't happen with our default block code, but it may with OpenSSL.
Note that we do call git_hash_free, which frees the memory we called
from git_hash_alloc, but doesn't discard the underlying context itself.
This can be seen with the following command when compiling with OpenSSL
and running with nightly Rust:
RUSTFLAGS='-Z sanitizer=leak' cargo test
Discard the context in our context handler. Note that it is fine to do
so even after finalizing the context, so our final functions which take
self instead of &mut self will not mishandle memory.

wt_status_collect_untracked() copies entries from dir.entries and
dir.ignored into string_lists using string_list_insert(). At first glance
this seems quadratic, because inserting into the sorted list may shift the
backing array, incurring O(n) work for each insert.
In practice, though, the entries in the dir struct are already sorted, so
we should not have to shift the array and only pay the O(log n) lookup cost
for each insertion. But this is subtle and depends on the behavior of
fill_directory().
Collect the entries with string_list_append() instead, then sort and
deduplicate each list once with string_list_sort_u(). This preserves the
sorted, duplicate-free result while making the collection strategy explicit.
