update a few Porcelain-ish for ref lock safety.
This updates the use of git-update-ref in git-branch, git-tag
and git-commit to make them safer in a few corner cases as
demonstration.
- git-tag makes sure that the named tag does not exist, allows
you to edit tag message and then creates the tag. If a tag
with the same name was created by somebody else in the
meantime, it used to happily overwrote it. Now it notices
the situation.

Fix broken sha1 locking
Current git#next is totally broken wrt. cloning over HTTP, generating refs
at random directories. Of course it's caused by the static get_pathname()
buffer. lock_ref_sha1() stores return value of mkpath()'s get_pathname()
call, then calls lock_ref_sha1_basic() which calls git_path(ref) which
calls get_pathname() at that point returning pointer to the same buffer.
So now you are sprintf()ing a format string into itself, wow! The resulting
pathnames are really cute. (If you've been paying attention, yes, the
mere fact that a format string _could_ write over itself is very wrong
and probably exploitable here. See the other mail I've just sent.)
I've never liked how we use return values of those functions so liberally,
the "allow some random number of get_pathname() return values to work
concurrently" is absolutely horrible pit and we've already fallen in this
before IIRC. I consider it an awful coding practice, you add a call
somewhere and at some other point some distant caller of that breaks since
it reuses the same return values. Not to mention this takes quite some time
to debug.
My gut feeling tells me that there might be more of this. I don't have
time to review the rest of the users of the refs.c functions though.

Enable the packed refs file format
This actually "turns on" the packed ref file format, now that the
infrastructure to do so sanely exists (ie notably the change to make the
reference reading logic take refnames rather than pathnames to the loose
objects that no longer necessarily even exist).
In particular, when the ref lookup hits a refname that has no loose file
associated with it, it falls back on the packed-ref information. Also, the
ref-locking code, while still using a loose file for the locking itself
(and _creating_ a loose file for the new ref) no longer requires that the
old ref be in such an unpacked state.
Finally, this does a minimal hack to git-checkout.sh to rather than check
the ref-file directly, do a "git-rev-parse" on the "heads/$refname".
That's not really wonderful - we should rather really have a special
routine to verify the names as proper branch head names, but it is a
workable solution for now.
With this, I can literally do something like
git pack-refs
find .git/refs -type f -print0 | xargs -0 rm -f --
and the end result is a largely working repository (ie I've done two
commits - which creates _one_ unpacked ref file - done things like run
"gitk" and "git log" etc, and it all looks ok).
There are probably things missing, but I'm hoping that the missing things
are now of the "small and obvious" kind, and that somebody else might want
to start looking at this too. Hint hint ;)

turn it into a pathname once we actually look it up in the filesystem.

yet, only for listing them (ie "for_each_ref()" and friends see the
packed refs, but none of the other single-ref lookup routines).
Note how we keep two separate lists: one for the loose refs, and one for
the packed refs we read. That's so that we can easily keep the two apart,
and read only one set or the other (and still always make sure that the
loose refs take precedence).
[ From this, it's not actually obvious why we'd keep the two separate
lists, but it's important to have the packed refs on their own list
later on, when I add support for looking up a single loose one.
For that case, we will want to read _just_ the packed refs in case the
single-ref lookup fails, yet we may end up needing the other list at
some point in the future, so keeping them separated is important ]

For the latter case, we assume wrongly that one call to

by call and the the pipe capacity can be larger than that (on current
Linux kernel, it is 65536 bytes). Therefore the child can write 32ko

POLLIN _and_ POLLHUP and the parent will read only 16ko of data.

apply --unidiff-zero: loosen sanity checks for --unidiff=0 patches
In "git-apply", we have a few sanity checks and heuristics that
expects that the patch fed to us is a unified diff with at least
one line of context.
* When there is no leading context line in a hunk, the hunk
must apply at the beginning of the preimage. Similarly, no
trailing context means that the hunk is anchored at the end.
* We learn a patch deletes the file from a hunk that has no
resulting line (i.e. all lines are prefixed with '-') if it
has not otherwise been known if the patch deletes the file.
Similarly, no old line means the file is being created.
And we declare an error condition when the file created by a
creation patch already exists, and/or when a deletion patch
still leaves content in the file.
These sanity checks are good safety measures, but breaks down
when people feed a diff generated with --unified=0. This was
recently noticed first by Matthew Wilcox and Gerrit Pape.
This adds a new flag, --unified-zero, to allow bypassing these
checks. If you are in control of the patch generation process,
you should not use --unified=0 patch and fix it up with this
flag; rather you should try work with a patch with context. But
if all you have to work with is a patch without context, this
flag may come handy as the last resort.

Add "git show-ref" builtin command
It's kind of like "git peek-remote", but works only locally (and thus
avoids the whole overhead of git_connect()) and has some extra
verification features.
For example, it allows you to filter the results, and to choose whether
you want the tag dereferencing or not. You can also use it to just test
whether a particular ref exists.
For example:
git show-ref master
will show all references called "master", whether tags or heads or
anything else, and regardless of how deep in the reference naming
hierarchy they are (so it would show "refs/heads/master" but also
"refs/remote/other-repo/master").
When using the "--verify" flag, the command requires an exact ref path:
git show-ref --verify refs/heads/master
will only match the exact branch called "master".
If nothing matches, show-ref will return an error code of 1, and in the
case of verification, it will show an error message.
For scripting, you can ask it to be quiet with the "--quiet" flag, which
allows you to do things like
git-show-ref --quiet --verify -- "refs/heads/$headname" ||
echo "$headname is not a valid branch"
to check whether a particular branch exists or not (notice how we don't
actually want to show any results, and we want to use the full refname for
it in order to not trigger the problem with ambiguous partial matches).
To show only tags, or only proper branch heads, use "--tags" and/or
"--heads" respectively (using both means that it shows tags _and_ heads,
but not other random references under the refs/ subdirectory).
To do automatic tag object dereferencing, use the "-d" or "--dereference"
flag, so you can do
git show-ref --tags --dereference
to get a listing of all tags together with what they dereference.

Fix git-am safety checks
An earlier commit
cbd64af added a check that prevents "git-am"
to run without its standard input connected to a terminal while
resuming operation. This was to catch a user error to try
feeding a new patch from its standard input while recovery.
The assumption of the check was that it is an indication that a
new patch is being fed if the standard input is not connected to
a terminal. It is however not quite correct (the standard input
can be /dev/null if the user knows the operation does not need
any input, for example). This broke t3403 when the test was run
with its standard input connected to /dev/null.
When git-am is given an explicit command such as --skip, there
is no reason to insist that the standard input is a terminal; we
are not going to read a new patch anyway.
Credit goes to Gerrit Pape for noticing and reporting the
problem with t3403-rebase-skip test.
