In 24876ebf68 (commit-reach(repo_in_merge_bases_many): report missing
commits, 2024-02-28), I taught `merge_submodule()` to handle errors
reported by `repo_in_merge_bases_many()`.
However, those errors were not passed through to the callers. That was
unintentional, and this commit remedies that.
Note that `find_first_merges()` can now also return -1 (because it
passes through that return value from `repo_in_merge_bases()`), and this
commit also adds the forgotten handling for that scenario.

The `merge_submodule()` function returns an integer that indicates
whether the merge was clean (returning 1) or unclean (returning 0).
Like the version in `merge-ort.c`, the version in `merge-recursive.c`
does not report any errors (such as repository corruption) by returning
-1 as of time of writing, even if the callers in `merge-ort.c` are
prepared for exactly such errors.
However, we want to teach (both variants of) the `merge_submodule()`
function that trick: to report errors by returning -1. Therefore,
prepare the caller in `merge-recursive.c` to handle that scenario.

Records store their keys prefix-compressed. As many records will share a
common prefix (e.g. "refs/heads/"), this can end up saving quite a bit
of disk space. The downside of this is that it is not possible to just
seek into the middle of a block and consume the corresponding record
because it may depend on prefixes read from preceding records.
To help with this usecase, the reftable format writes every n'th record
without using prefix compression, which is called a "restart". The list
of restarts is stored at the end of each block so that a reader can
figure out entry points at which to read a full record without having to
read all preceding records.
This allows us to do a binary search over the records in a block when
searching for a particular key by iterating through the restarts until
we have found the section in which our record must be located. From
thereon we perform a linear search to locate the desired record.
This mechanism is broken though. In `block_reader_seek()` we call
`binsearch()` over the count of restarts in the current block. The
function we pass to compare records with each other computes the key at
the current index and then compares it to our search key by calling
`strbuf_cmp()`, returning its result directly. But `binsearch()` expects
us to return a truish value that indicates whether the current index is
smaller than the searched-for key. And unless our key exactly matches
the value at the restart counter we always end up returning a truish
value.
The consequence is that `binsearch()` essentially always returns 0,
indicacting to us that we must start searching right at the beginning of
the block. This works by chance because we now always do a linear scan
from the start of the block, and thus we would still end up finding the
desired record. But needless to say, this makes the optimization quite
useless.
Fix this bug by returning whether the current key is smaller than the
searched key. As the current behaviour was correct it is not possible to
write a test. Furthermore it is also not really possible to demonstrate
in a benchmark that this fix speeds up seeking records.
This may cause the reader to question whether this binary search makes
sense in the first place if it doesn't even help with performance. But
it would end up helping if we were to read a reftable with a much larger
block size. Blocks can be up to 16MB in size, in which case it will
become much more important to avoid the linear scan. We are not yet
ready to read or write such larger blocks though, so we have to live
without a benchmark demonstrating this.

When decoding records it is customary to reuse a `struct
reftable_ref_record` across calls. Thus, it may happen that the record
already holds some allocated memory. When decoding ref and log records
we handle this by releasing or reallocating held memory. But we fail to
do this for object records, which causes us to leak memory.
Fix this memory leak by releasing object records before we decode into
them. We may eventually want to reuse memory instead to avoid needless
reallocations. But for now, let's just plug the leak and be done.

If
(a) There is a "---" divider in a commit message,
(b) At some point beyond that divider, there is a cut-line (that is,
"# ------------------------ >8 ------------------------") in the
commit message,
(c) the user does not explicitly set the "no-divider" option,
then "git interpret-trailers" will hang indefinitively.
This is because when (a) is true, find_end_of_log_message() will invoke
ignored_log_message_bytes() with a len that is intended to make it
ignore the part of the commit message beyond the divider. However,
ignored_log_message_bytes() calls wt_status_locate_end(), and that
function ignores the length restriction when it tries to locate the cut
line. If it manages to find one, the returned cutoff value is greater
than len. At this point, ignored_log_message_bytes() goes into an
infinite loop, because it won't advance the string parsing beyond len,
but the exit condition expects to reach cutoff.
Make wt_status_locate_end() honor the length parameter passed in, to
fix this issue.
In general, if wt_status_locate_end() is given a piece of the memory
that lacks NUL at all, strstr() may continue across page boundaries
and run into an unmapped page. For our current callers, this is not
a problem, as all of them except one uses a memory owned by a strbuf
(which guarantees an implicit NUL-termination after its payload),
and the one exception in trailer.c:find_end_of_log_message() uses
strlen() to compute the length before calling this function.

Teach fsmonitor_refresh_callback() to handle case-insensitive
lookups if case-sensitive lookups fail on case-insensitive systems.
This can cause 'git status' to report stale status for files if there
are case issues/errors in the worktree.
The FSMonitor daemon sends FSEvents using the observed spelling
of each pathname. On case-insensitive file systems this may be
different than the expected case spelling.
The existing code uses index_name_pos() to find the cache-entry for
the pathname in the FSEvent and clear the CE_FSMONITOR_VALID bit so
that the worktree scan/index refresh will revisit and revalidate the
path.
On a case-insensitive file system, the exact match lookup may fail
to find the associated cache-entry. This causes status to think that
the cached CE flags are correct and skip over the file.

if necessary.
