A few preliminary minor clean-ups in the area around submodules.
* sb/submodule-cleanup:

"git rebase -i", when a 'merge <branch>' insn in its todo list
fails, segfaulted, which has been (minimally) corrected.

rebase -i: fix SIGSEGV when 'merge <branch>' fails
t3430: add conflicting commit
When "git rebase -i" is told to squash two or more commits into
one, it labeled the log message for each commit with its number.
It correctly called the first one "1st commit", but the next one
was "commit #1", which was off-by-one. This has been corrected.

rebase -i: fix numbering in squash message
Recent update to "git config" broke updating variable in a
subsection, which has been corrected.

git-config: document accidental multi-line setting in deprecated syntax
config: fix case sensitive subsection names on writing
t1300: document current behavior of setting options
After a partial clone, repeated fetches from promisor remote would
have accumulated many packfiles marked with .promisor bit without
getting them coalesced into fewer packfiles, hurting performance.
"git repack" now learned to repack them.

The API to iterate over all objects learned to optionally list
objects in the order they appear in packfiles, which helps locality
of access if the caller accesses these objects while as objects are
enumerated.

commands at wrong places, which has been corrected.
* js/rebase-merges-exec-fix:
rebase --exec: make it work with --rebase-merges
t3430: demonstrate what -r, --autosquash & --exec should do
"git pull --rebase=interactive" learned "i" as a short-hand for
"interactive".

pull --rebase=<type>: allow single-letter abbreviations for the type
"git merge --abort" etc. did not clean things up properly when
there were conflicted entries in the index in certain order that

* en/abort-df-conflict-fixes:
read-cache: fix directory/file conflict handling in read_index_unmerged()
t1015: demonstrate directory/file conflict recovery failures
The http-backend (used for smart-http transport) used to slurp the
whole input until EOF, without paying attention to CONTENT_LENGTH
that is supplied in the environment and instead expecting the Web
server to close the input stream. This has been fixed.
* mk/http-backend-content-length:
t5562: avoid non-portable "export FOO=bar" construct
http-backend: respect CONTENT_LENGTH for receive-pack
http-backend: respect CONTENT_LENGTH as specified by rfc3875
http-backend: cleanup writing to child process
Update to a few other topics around 'git fetch'.
* ab/fetch-nego:
fetch doc: cross-link two new negotiation options
negotiator: unknown fetch.negotiationAlgorithm should error out
"git fetch $there refs/heads/s" ought to fetch the tip of the
branch 's', but when "refs/heads/refs/heads/s", i.e. a branch whose
name is "refs/heads/s" exists at the same time, fetched that one
instead by mistake. This has been corrected to honor the usual
disambiguation rules for abbreviated refnames.
* jt/refspec-dwim-precedence-fix:
remote: make refspec follow the same disambiguation rule as local refs
The automatic tree-matching in "git merge -s subtree" was broken 5
years ago and nobody has noticed since then, which is now fixed.
* jk/merge-subtree-heuristics:
score_trees(): fix iteration over trees with missing entries
The test performed at the receiving end of "git push" to prevent
bad objects from entering repository can be customized via
receive.fsck.* configuration variables; we now have gained a
counterpart to do the same on the "git fetch" side, with
fetch.fsck.* configuration variables.

If a merge command in the todo list specifies just a branch to merge
with no -C/-c argument then item->commit is NULL. This means that if
there are merge conflicts error_with_patch() is passed a NULL commit
which causes a segmentation fault when make_patch() tries to look it up.
This commit implements a minimal fix which fixes the crash and allows
the user to successfully commit a conflict resolution with 'git rebase
--continue'. It does not write .git/rebase-merge/patch,
.git/rebase-merge/stopped-sha or update REBASE_HEAD. To sensibly get the
hashes of the merge parents would require refactoring do_merge() to
extract the code that parses the merge parents into a separate function
which error_with_patch() could then use to write the parents into the
stopped-sha file. To create meaningful output make_patch() and 'git
rebase --show-current-patch' would also need to be modified to diff the
merge parent and merge base in this case.

The test 'pack-objects to file can use bitmap' added in 645c432d61
(pack-objects: use reachability bitmap index when generating
non-stdout pack, 2016-09-10) is silently buggy and doesn't check what
it's supposed to.
In 't5310-pack-bitmaps.sh', the 'list_packed_objects' helper function
does what its name implies by running:
git show-index <"$1" | cut -d' ' -f2
The test in question invokes this function like this:
list_packed_objects <packa-$packasha1.idx >packa.objects &&
list_packed_objects <packb-$packbsha1.idx >packb.objects &&
test_cmp packa.objects packb.objects
Note how these two callsites don't specify the name of the pack index
file as the function's parameter, but redirect the function's standard
input from it. This triggers an error message from the shell, as it
has no filename to redirect from in the function, but this error is
ignored, because it happens upstream of a pipe. Consequently, both
invocations produce empty 'pack{a,b}.objects' files, and the
subsequent 'test_cmp' happily finds those two empty files identical.
Fix these two 'list_packed_objects' invocations by specifying the pack
index files as parameters. Furthermore, eliminate the pipe in that
function by replacing it with an &&-chained pair of commands using an
intermediate file, so a failure of 'git show-index' or the shell
redirection will fail the test.

If you're going to access the contents of every object in a
packfile, it's generally much more efficient to do so in
pack order, rather than in hash order. That increases the
locality of access within the packfile, which in turn is
friendlier to the delta base cache, since the packfile puts
related deltas next to each other. By contrast, hash order
is effectively random, since the sha1 has no discernible
relationship to the content.
This patch introduces an "--unordered" option to cat-file
which iterates over packs in pack-order under the hood. You
can see the results when dumping all of the file content:
$ time ./git cat-file --batch-all-objects --buffer --batch | wc -c
6883195596
real 0m44.491s
user 0m42.902s
sys 0m5.230s
$ time ./git cat-file --unordered \
--batch-all-objects --buffer --batch | wc -c
6883195596
real 0m6.075s
user 0m4.774s
sys 0m3.548s
Same output, different order, way faster. The same speed-up
applies even if you end up accessing the object content in a
different process, like:
git cat-file --batch-all-objects --buffer --batch-check |
grep blob |
git cat-file --batch='%(objectname) %(rest)' |
wc -c
Adding "--unordered" to the first command drops the runtime
in git.git from 24s to 3.5s.
Side note: there are actually further speedups available
for doing it all in-process now. Since we are outputting
the object content during the actual pack iteration, we
know where to find the object and could skip the extra
lookup done by oid_object_info(). This patch stops short
of that optimization since the underlying API isn't ready
for us to make those sorts of direct requests.
So if --unordered is so much better, why not make it the
default? Two reasons:
1. We've promised in the documentation that --batch-all-objects
outputs in hash order. Since cat-file is plumbing,
people may be relying on that default, and we can't
change it.
2. It's actually _slower_ for some cases. We have to
compute the pack revindex to walk in pack order. And
our de-duplication step uses an oidset, rather than a
sort-and-dedup, which can end up being more expensive.
If we're just accessing the type and size of each
object, for example, like:
git cat-file --batch-all-objects --buffer --batch-check
my best-of-five warm cache timings go from 900ms to
1100ms using --unordered. Though it's possible in a
cold-cache or under memory pressure that we could do
better, since we'd have better locality within the
packfile.
And one final question: why is it "--unordered" and not
"--pack-order"? The answer is again two-fold:
1. "pack order" isn't a well-defined thing across the
whole set of objects. We're hitting loose objects, as
well as objects in multiple packs, and the only
ordering we're promising is _within_ a single pack. The
rest is apparently random.
2. The point here is optimization. So we don't want to
promise any particular ordering, but only to say that
we will choose an ordering which is likely to be
efficient for accessing the object content. That leaves
the door open for further changes in the future without
having to add another compatibility option.
