df6e874496 diff.h: remove unnecessary include of oidset.h
This also made it clear that several .c files depended upon various
things that oidset included, but had omitted the direct #include for
those headers.  Add those now.

bc5c5ec044 cache.h: remove this no-longer-used header
Since this header showed up in some places besides just #include
statements, update/clean-up/remove those other places as well.

Note that compat/fsmonitor/fsm-path-utils-darwin.c previously got
away with violating the rule that all files must start with an include
of git-compat-util.h (or a short-list of alternate headers that happen
to include it first).  This change exposed the violation and caused it
to stop building correctly; fix it by having it include
git-compat-util.h first, as per policy.

08c46a499a read-cache*.h: move declarations for read-cache.c functions from cache.h
For the functions defined in read-cache.c, move their declarations from
cache.h to a new header, read-cache-ll.h.  Also move some related inline
functions from cache.h to read-cache.h.  The purpose of the
read-cache-ll.h/read-cache.h split is that about 70% of the sites don't
need the inline functions and the extra headers they include.

f394e093df treewide: be explicit about dependence on gettext.h
Dozens of files made use of gettext functions, without explicitly
including gettext.h.  This made it more difficult to find which files
could remove a dependence on cache.h.  Make C files explicitly include
gettext.h if they are using it.

However, while compat/fsmonitor/fsm-ipc-darwin.c should also gain an
include of gettext.h, it was left out to avoid conflicting with an
in-flight topic.

a6dc3d364c treewide: remove unnecessary cache.h inclusion from a few headers
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.

bdafeae0b9 cache.h & test-tool.h: add & use "USE_THE_INDEX_VARIABLE"
In a preceding commit we fully applied the
"index-compatibility.pending.cocci" rule to "t/helper/*".

Let's now stop defining "USE_THE_INDEX_COMPATIBILITY_MACROS" in
test-tool.h itself, and instead instead define
"USE_THE_INDEX_VARIABLE" in the individual test helpers that need
it. This mirrors how we do the same thing in the "builtin/" directory.

c541e77cf8 test-fast-rebase helper: use release_revisions() (again)
Fix a bug in 0139c58ab9 (revisions API users: add "goto cleanup" for
release_revisions(), 2022-04-13), in that commit a release_revisions()
call was added to this function, but it never did anything due to this
TODO memset() added in fe1a21d526 (fast-rebase: demonstrate
merge-ort's API via new test-tool command, 2020-10-29).

Simply removing the memset() will fix the "cmdline" which can be seen
when running t5520-pull.sh.

This sort of thing could be detected automatically with a rule similar
to the unused.cocci merged in 7fa60d2a5b (Merge branch
'ab/cocci-unused' into next, 2022-07-11). The following rule on top
would catch the case being fixed here:

	@@
	type T;
	identifier I;
	identifier REL1 =~ "^[a-z_]*_(release|reset|clear|free)$";
	identifier REL2 =~ "^(release|clear|free)_[a-z_]*$";
	@@

	- memset(\( I \| &I \), 0, ...);
	  ... when != \( I \| &I \)
	(
	  \( REL1 \| REL2 \)( \( I \| &I \), ...);
	|
	  \( REL1 \| REL2 \)( \( &I \| I \) );
	)
	  ... when != \( I \| &I \)

That rule should arguably use only &I, not I (as we might be passed a
pointer). The distinction would matter if anyone cared about the
side-effects of a memset() followed by release() of a pointer to a
variable passed into the function.

As such a pattern would be at best very confusing, and most likely
point to buggy code as in this case, the above rule is probably fine
as-is.

But as this rule only found one such bug in the entire codebase let's
not add it to contrib/coccinelle/unused.cocci for now, we can always
dig it up in the future if it's deemed useful.

b925fcf129 t/helper/test-fast-rebase.c: don't leak "struct strbuf"
Fix a memory leak that's been with us since f9500261e0 (fast-rebase:
write conflict state to working tree, index, and HEAD, 2021-05-20)
changed this code to move these strbuf_release() into an if/else
block.

We'll also add to "reflog_msg" in the "else" arm of the "if" block
being modified here, and we'll append to "branch_msg" in both
cases. But after f9500261e0 only the "if" block would free these two
"struct strbuf".

f9500261e0 fast-rebase: write conflict state to working tree, index, and HEAD
Previously, when fast-rebase hit a conflict, it simply aborted and left
HEAD, the index, and the working tree where they were before the
operation started.  While fast-rebase does not support restarting from a
conflicted state, write the conflicted state out anyway as it gives us a
way to see what the conflicts are and write tests that check for them.

This will be important in the upcoming commits, because sequencer.c is
only superficially integrated with merge-ort.c; in particular, it calls
merge_switch_to_result() after EACH merge instead of only calling it at
the end of all the sequence of merges (or when a conflict is hit).  This
not only causes needless updates to the working copy and index, but also
causes all intermediate data to be freed and tossed, preventing caching
information from one merge to the next.  However, integrating
sequencer.c more deeply with merge-ort.c is a big task, and making this
small extension to fast-rebase.c provides us with a simple way to test
the edge and corner cases that we want to make sure continue working.

caba91c373 fast-rebase: change assert() to BUG()
assert() can succinctly document expectations for the code, and do so in
a way that may be useful to future folks trying to refactor the code and
change basic assumptions; it allows them to more quickly find some
places where their violations of previous assumptions trips things up.

Unfortunately, assert() can surround a function call with important
side-effects, which is a huge mistake since some users will compile with
assertions disabled.  I've had to debug such mistakes before in other
codebases, so I should know better.  Luckily, this was only in test
code, but it's still very embarrassing.  Change an assert() to an if
(...) BUG (...).

fe1a21d526 fast-rebase: demonstrate merge-ort's API via new test-tool command
Add a new test-tool command named 'fast-rebase', which is a
super-slimmed down and nowhere near as capable version of 'git rebase'.
'test-tool fast-rebase' is not currently planned for usage in the
testsuite, but is here for two purposes:

  1) Demonstrate the desired API of merge-ort.  In particular,
     fast-rebase takes advantage of the separation of the merging
     operation from the updating of the index and working tree, to
     allow it to pick N commits, but only update the index and working
     tree once at the end.  Look for the calls to
     merge_incore_nonrecursive() and merge_switch_to_result().

  2) Provide a convenient benchmark that isn't polluted by the heavy
     disk writing and forking of unnecessary processes that comes from
     sequencer.c and merge-recursive.c.  fast-rebase is not meant to
     replace sequencer.c, just give ideas on how sequencer.c can be
     changed.  Updating sequencer.c with these goals is probably a
     large amount of work; writing a simple targeted command with
     no documentation, less-than-useful help messages, numerous
     limitations in terms of flags it can accept and situations it can
     handle, and which is flagged off from users is a much easier
     interim step.
