rev_info.early_output started out as an unsigned int in cdcefbc97 (Add
"--early-output" log flag for interactive GUI use, 2007-11-03), but
later it was turned into a single bit in a bit field in cc243c3ce
(show: --ignore-missing, 2011-05-18) without explanation, though the
code using it still expects it to be a regular integer type and uses
it as a counter. Consequently, any even number given via
'--early-output=<N>', or indeed a plain '--early-output' defaulting to
100 effectively disabled the feature.
Turn rev_info.early_output back into its origin unsigned int data
type, making '--early-output' work again.

Similar functions exist in apply.c and builtin/show-branch.c for
counting the number of slashes in a string. Also in the later
patches, we introduce a third caller for the same. Hence, we unify
it now by cleaning the existing functions and declaring a common
function count_slashes in dir.h and implementing it in dir.c to
remove this code duplication.

Commit 28ed9830b1 (get_packed_ref_cache(): assume "packed-refs" won't
change while locked, 2017-05-22) assumes that the "packed-refs" file
cannot change while we hold the lock. That assumption is
justified *if* the lock has been held the whole time since the
"packed-refs" file was last read.
But in `lock_packed_refs()`, we ourselves lock the "packed-refs" file
and then call `get_packed_ref_cache()` to ensure that the cache agrees
with the file. The intent is to guard against the possibility that
another process changed the "packed-refs" file the moment before we
locked it.
This check was defeated because `get_packed_ref_cache()` saw that the
file was locked, and therefore didn't do the `stat_validity_check()`
that we want.
The mistake was compounded with a misleading comment in
`lock_packed_refs()` claiming that it was doing the right thing. That
comment came from an earlier draft of the mh/packed-ref-store-prep
patch series when the commits were in a different order.
So instead:
* Extract a function `validate_packed_ref_cache()` that does the
validity check independent of whether the lock is held.
* Change `get_packed_ref_cache()` to call the new function, but only
if the lock *isn't* held.
* Change `lock_packed_refs()` to call the new function in any case
before calling `get_packed_ref_cache()`.
* Fix the comment in `lock_packed_refs()`.

In 618e613a70, 10 years ago, the default for pack depth used for
git-pack-objects and git-repack was changed from 10 to 50, while
leaving fast-import's default to 10.
There doesn't seem to be a reason besides oversight for the change not
having happened in fast-import as well.
Interestingly, fast-import uses pack.depth when it's set, and the
git-config manual says the default for pack.depth is 50. While the
git-fast-import manual does say the default depth is 10, the
inconsistency is also confusing.

Update sha1dc from the latest version by the upstream
maintainer[1].
See commit a0103914c2 ("sha1dc: update from upstream", 2017-05-20) for
the latest update. That update was done sans some whitespace changes
by upstream, which is why the diff here isn't the same as the upstream
cc46554..e139984.
It also brings in a change[2] upstream made which should hopefully
address the breakage in 2.13.1 on Cygwin, see [3]. Cygwin defines both
_BIG_ENDIAN and _LITTLE_ENDIAN.
Adam Dinwoodie reports on the mailing list that that upstream commit
fixes the issue on Cygwin[4].

The upstream sha1dc code indents some lines with spaces.
While this doesn't match Git's coding guidelines, it's better
to leave this imported code untouched than to try to make it
match our style. However, we can use .gitattributes to tell
"diff --check" and "git am" not to bother us about it.

Commit a1283866b (t5313: test bounds-checks of
corrupted/malicious pack/idx files, 2016-02-25) added a test
that requires our corrupted pack index to have two objects.
The entry for the first one remains untouched, but we
corrupt the entry for second one. Since the index stores the
entries in sha1-sorted order, this means that the test must
make sure that the sha1 of the object we expect to be
corrupted ("$object") sorts after the other placeholder
object.
That commit used the HEAD commit as the placeholder, but the
script never calls test_tick. That means that the commit
object (and thus its sha1) depends on the timestamp when the
test script is run. This usually works in practice, because
the sha1 of $object starts with "fff". The commit object
will sort after that only 1 in 4096 times, but when it does
the test will fail.
One obvious solution is to add the test_tick call to get a
deterministic commit sha1. But since we're relying on the
sort order for the test to function, let's make that very
explicit by just generating a second blob with a known sha1.

Since commit 99caeed05 (Let 'git <command> -h' show usage
without a git dir, 2009-11-09), the git wrapper handles "-h"
specially, skipping any repository setup but still calling
the builtin's cmd_foo() function. This means that every
cmd_foo() must be ready to handle this case, but we don't
have any systematic tests. This led to "git am -h" being
broken for some time without anybody noticing.
This patch just tests that "git foo -h" works for every
builtin, where we see a 129 exit code (the normal code for
our usage() helper), and that the word "usage" appears in
the output.

It can be useful in the test suite to be able to iterate
over the list of builtins. We could do this with some
Makefile magic. But since the authoritative list is in the

handy for debugging, let's add a hidden command-line option
to dump that list.

The "git version" command didn't traditionally accept any
options, and in fact ignores any you give it. When we added
simple option parsing for "--build-options" in 6b9c38e14, we
didn't improve this; we just loop over the arguments and
pick out the one we recognize.
Instead, let's move to a real parsing loop, complain about
nonsense options, and recognize conventions like "-h".

"git $builtin -h" bypasses the usual repository setup and calls the
cmd_$builtin() function, expecting it to show the help text.
Unfortunately the commands in the log- and the diff- family want to
call into the revisions machinery, which by definition needs to have
a repository already discovered. Strictly speaking, they may not
need a repository only for parsing "-h", but it is a good discipline
to future-proof codepath to ensure that setup_revisions() is called
after we know that a repository is there.
Handle the "git $builtin -h" special case very early in these
commands to work around potential issues.
