"git $cmd -h" for builtin commands calls the implementation of the

When an existing repository is used for t/perf testing, we first
create bit-for-bit copy of it, which may grab a transient state of
the repository and freeze it into the repository used for testing,
which then may cause Git operations to fail. Single out "the index
being locked" case and forcibly drop the lock from the copy.

The convention for a command line is to follow "git cmdname
--options" with revisions followed by an optional "--"
disambiguator and then finally pathspecs. When "--" is not there,
we make sure early ones are all interpretable as revs (and do not
look like paths) and later ones are the other way around. A
pathspec with "magic" (e.g. ":/p/a/t/h" that matches p/a/t/h from
the top-level of the working tree, no matter what subdirectory you
are working from) are conservatively judged as "not a path", which
required disambiguation more often. The command line parser
learned to say "it's a pathspec" a bit more often when the syntax
looks like so.

verify_filename(): flip order of checks
verify_filename(): treat ":(magic)" as a pathspec

We added an FREAD_READS_DIRECTORIES Makefile knob long ago
in cba22528f (Add compat/fopen.c which returns NULL on
attempt to open directory, 2008-02-08) to handle systems
where reading from a directory returned garbage. This works
by catching the problem at the fopen() stage and returning
NULL.
More recently, we found that there is a class of systems
(including Linux) where fopen() succeeds but fread() fails.
Since the solution is the same (having fopen return NULL),
they use the same Makefile knob as of e2d90fd1c
(config.mak.uname: set FREAD_READS_DIRECTORIES for Linux and
FreeBSD, 2017-05-03).
This works fine except for one thing: the autoconf test in
configure.ac to set FREAD_READS_DIRECTORIES actually checks
whether fread succeeds. Which means that on Linux systems,
the knob isn't set (and we even override the config.mak.uname
default). t1308 catches the failure.
We can fix this by tweaking the autoconf test to cover both
cases. In theory we might care about the distinction between
the traditional "fread reads directories" case and the new
"fopen opens directories". But since our solution catches
the problem at the fopen stage either way, we don't actually
need to know the difference. The "fopen" case is a superset.
This does mean the FREAD_READS_DIRECTORIES name is slightly
misleading. Probably FOPEN_OPENS_DIRECTORIES would be more
accurate. But it would be disruptive to simply change the
name (people's existing build configs would fail), and it's
not worth the complexity of handling both. Let's just add a
comment in the knob description.

Our code often opens a path to an optional file, to work on its
contents when we can successfully open it. We can ignore a failure
to open if such an optional file does not exist, but we do want to
report a failure in opening for other reasons (e.g. we got an I/O
error, or the file is there, but we lack the permission to open).
The exact errors we need to ignore are ENOENT (obviously) and
ENOTDIR (less obvious). Instead of repeating comparison of errno
with these two constants, introduce a helper function to do so.

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
commands array inside git.c, and since this could also be
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.
