A new option, --allow-binary-replacement, is introduced.
When you feed a diff that records full SHA1 name of pre- and
post-image blob on its index line to git-apply with this option,
the post-image blob replaces the path if what you have in the
working tree matches the pre-image _and_ post-image blob is
already available in the object directory.
Later we _might_ want to enhance the diff output to also include
the full binary data of the post-image, to make this more
useful, but this is good enough for local rebasing application.

This makes it possible to have a "sparse" git object subdirectory
structure, something that has become much more attractive now that people
use pack-files all the time.
As a result of pack-files, a git object directory doesn't necessarily have
any individual objects lying around, and in that case it's just wasting
space to keep the empty first-level object directories around: on many
filesystems the 256 empty directories will be aboue 1MB of diskspace.
Even more importantly, after you re-pack a project that _used_ to be
unpacked, you could be left with huge directories that no longer contain
anything, but that waste space and take time to look through.
With this change, "git prune-packed" can just do an rmdir() on the
directories, and they'll get removed if empty, and re-created on demand.
This patch also tries to fix up "write_sha1_from_fd()" to use the new
common infrastructure for creating the object files, closing a hole where
we might otherwise leave half-written objects in the object database.
[jc: I unoptimized the part that really removes the fan-out directories
to ease transition. init-db still wastes 1MB of diskspace to hold 256
empty fan-outs, and prune-packed rmdir()'s the grown but empty directories,
but runs mkdir() immediately after that -- reducing the saving from 150KB
to 146KB. These parts will be re-introduced when everybody has the
on-demand capability.]

I have noticed that "make test" fails without any explanations when the
"merge" utility is missing. I don't think tests should be silent in
case of failure.
It turned out that the particular test was using "exit" to interrupt the
test in case of an error. This caused the whole test script to exit.
No further tests would be run even if "--immediate" wasn't specified.
No error message was printed.
This patch does following:
All instances of "exit", "exit 1" and "(exit 1)" in tests have been
replaced with "return 1". In fact, "(exit 1)" had no effect.
File descriptor 5 is duplicated from file descriptor 1. This is needed
to print important error messages from tests.
New function test_run_() has been introduced. Any "return" in the test
would merely cause that function to return without skipping calls to
test_failure_() and test_ok_(). The new function also traps "exit" and
treats it like a fatal error (in case somebody reintroduces "exit" in
the tests).
test_expect_failure() and test_expect_success() check both the result of
eval and the return value of test_run_(). If the later is not 0, it's
always a failure because it indicates the the test didn't complete.

This adds more tests for --emu23. One is to show how it can
carry forward more local changes than the straightforward
two-way fast forward, and another is to show the recent
overeager optimization of directory/file conflict check broke
things, which will be fixed in the next commit.

1. --merge-order doesn't deal properly with a specified head that has no parent
* FAIL 11: head has no parent
2. --merge-order doesn't deal properly with arguments of the form
head ^head
* FAIL 30: head ^head --merge-order git-rev-list --merge-order
--show-breaks a3 ^a3
3. if one of the specified heads is reachable from the other, the
head gets printed twice and this causes problems for upcoming
versions of gitk. This is true for both --merge-order and non
--merge-order style of invocations.
* FAIL 24: one specified head reachable from another a4, c3, --merge-order
* FAIL 26: one specified head reachable from another a4, c3, no --merge-order
* FAIL 27: one specified head reachable from another c3, a4, no --merge-order
4. --merge-order aborts with commits that list the same parent twice...it should handle it more gracefully.
* no longer unit testable
5. broken interaction between --merge-order and --max-age
previously posted as:
"[PATCH 1/2] Test case that demonstrates problem with --merge-order, --max-age interaction"
* FAIL 23: --max-age=c3, --merge-order
Later patches in this patch set fix these problems.

Patch for a completely rewritten file detected by the -B flag
was shown as a pair of creation followed by deletion in earlier
versions. This was an misguided attempt to make reviewing such
a complete rewrite easier, and unnecessarily ended up confusing
git-apply. Instead, show the entire contents of old version
prefixed with '-', followed by the entire contents of new
version prefixed with '+'. This gives the same easy-to-review
for human consumer while keeping it a single, regular
modification patch for machine consumption, something that even
GNU patch can grok.

Like diff-tree, this patch makes -C option for diff-* brothers
to use only pre-image of modified files as rename/copy detection
by default. Give --find-copies-harder to use unmodified files
to find copies from as well.
This also fixes "diff-files -C" problem earlier noticed by
Linus. It was feeding the null sha1 even when the file in the
work tree was known to match what is in the index file. This
resulted in diff-files showing everything in the project.

This patch teaches read-tree 3-way merge that, when only "the
other tree" changed a path, and if the index file already has
the same change, we are not in a situation that would clobber
the index and the work tree, and lets the merge succeed; this is
case #14ALT in t1000 test. It does not change the result of the
merge, but prevents it from failing when it does not have to.

This adds #3ALT rule (and #2ALT rule for symmetry) to the
read-tree 3-way merge logic that collapses paths that are added
only in one branch and not in the other internally.
This makes --emu23 to succeed in the last remaining case where
the pure 2-way merge succeeded and earlier one failed. Running
diff between t1001 and t1005 test scripts shows that the only
difference between the two is that --emu23 can leave the states
into separate stages so that the user can use usual 3-way merge
resolution techniques to carry forward the local changes when
pure 2-way merge would have refused to run.

This fixes too strong index requirement 3-way merge enforces in
one case: the same file is added in both branches.
In this case, the original code insisted that if the index file
has that path, it must match our branch and be up-to-date.
However in this particular case, it only has to match it, and
can be dirty. We just need to make sure that we keep the
work-tree copy instead of checking out the merge result.
The resolution of such a path, however, cannot be left to
outside script, because we will not keep the original stage0
entries for unmerged paths when read-tree finishes, and at that
point, the knowledge of "if we resolve it to match the new file
added in both branches, the merge succeeds and the work tree
would not lose information, but we should _not_ update the work
tree from the resulting index file" is lost. For this reason,
the now code needs to resolve this case (#5ALT) internally.
This affects some existing tests in the test suite, but all in
positive ways. In t1000 (3-way test), this #5ALT case now gets
one stage0 entry, instead of an identical stage2 and stage3
entry pair, for such a path, and one test that checked for merge
failure (because the test assumed the "stricter-than-necessary"
behaviour) does not have to fail anymore. In t1005 (emu23
test), two tests that involves a case where the work tree
already had a change introduced in the upstream (aka "merged
head"), the merge succeeds instead of failing.

This new flag causes two-way fast forward to internally use the
three-way merge mechanism. This behaviour is intended to offer
a better fast forward semantics when used in a dirty work tree.
The new test t1005 is parallel to the existing t1001 "pure
2-way" tests, but some parts that are commented out would fail.
These failures are due to three-way merge enforcing too strict
index requirements for cases that could succeed. This problem
will be addressed by later patches.
Without even changing three-way mechanism, the --emu23 two-way
fast forward already gives the user an easier-to-handle merge
result when a file that "merged head" updates has local
modifications. This is demonstrated as "case 16" test in t1005.
