This adds the ability to actually create delta objects using a new tool:
git-mkdelta. It uses an ordered list of potential objects to deltafy
against earlier objects in the list. A cap on the depth of delta
references can be provided as well, otherwise the default is to not have
any limit. A limit of 0 will also undeltafy any given object.
Also provided is the beginning of a script to deltafy an entire
repository.

This makes the core code aware of delta objects and undeltafy them as
needed. The convention is to use read_sha1_file() to have
undeltafication done automatically (most users do that already so this
is transparent).
If the delta object itself has to be accessed then it must be done
through map_sha1_file() and unpack_sha1_file().
In that context mktag.c has been switched to read_sha1_file() as there
is no reason to do the full map+unpack manually.

Fix various things that sparse complains about:
- use NULL instead of 0
- make sure we declare everything properly, or mark it static
- use proper function declarations ("fn(void)" instead of "fn()")
Sparse is always right.
Instead of swapping the arguments just before output, this patch
makes the swapping happen on the input side of the diff core,
when "reverse-diff" is in effect. This greatly simplifies the
logic, but more importantly it is necessary for upcoming "copy
detection" work.

The same check we added earlier to update-cache to catch ENOTDIR
turns out to be missing from diff-files. This causes a
difference not being reported when you have DF/DF (a file in a
subdirectory) in the cache and DF is a file on the filesystem.

This one compares two pathnames that may be partial basenames, not
full paths. We need to get the path sorting right, since a directory
name will sort as if it had the final '/' at the end.
Add '-R' flag to diff-tree, and change the test subdirectory
shell files to be executable (something that Junio couldn't
get me to do through the pure patch with my current patch
handling infrastructure).
This cleans up the way calls are made into the diff core from diff-tree
family and diff-helper. Earlier, these programs had "if
(generating_patch)" sprinkled all over the place, but those ugliness are
gone and handled uniformly from the diff core, even when not generating
patch format.
This also allowed diff-cache and diff-files to acquire -R
(reverse) option to generate diff in reverse. Users of
diff-tree can swap two trees easily so I did not add -R there.
[ Linus' note: I'll add -R to "diff-tree" too, since a "commit
diff" doesn't have another tree to switch around: the other
tree is always the parent(s) of the commit ]
Also -M<digits-as-mantissa> suggestion made by Linus has been
implemented.
Documentation updates are also included.

This moves the git manpage to man7, since "git" isn't a direct command
per se. It also does two other things:
* Sort of works around the asciidoc 6.0.3 bug where the manpages all
get called "git.1". It just renames them to what they should have
been called.
* Fixes a cut-n-paste bug in git-diff-helper.txt that was making
asciidoc choke.

This rips out the rename detection engine from diff-helper and moves it
to the diff core, and updates the internal calling convention used by
diff-tree family into the diff core. In order to give the same option
name to diff-tree family as well as to diff-helper, I've changed the
earlier diff-helper '-r' option to '-M' (stands for Move; sorry but the
natural abbreviation 'r' for 'rename' is already taken for 'recursive').
Although I did a fair amount of test with the git-diff-tree with
existing rename commits in the core GIT repository, this should still be
considered beta (preview) release. This patch depends on the diff-delta
infrastructure just committed.
This implements almost everything I wanted to see in this series of
patch, except a few minor cleanups in the calling convention into diff
core, but that will be a separate cleanup patch.

I just remembered why I placed that bogus "sb->len ==0 implies
sb->eof" condition there. We need at least something like this
to catch the normal EOF (that is, line termination immediately
followed by EOF) case. "if (feof(fp))" fires when we have
already read the eof, not when we are about read it.

Fix diff parsing for created and deleted files
This normally doesn't matter, but if you have a filename that is
sometimes a directory and sometimes a regular file (or symlink),
we don't want the regular file case to trigger a "partial match".
We used to trigger the "interesting subdirectory" check for any
matching name that started with the same character series, regardless
of whether it had the matching slash or not.
We can't just do the "sha1_to_hex()" thing directly, since the
buffer in question will be overwritten by the name of the parent.
So teach diff_tree_commit() to generate the proper hex name itself.
We use "--" to mark end of command line switches, not "-". Also,
allow more flexibility in the passed-in sha1 names, in that a
single sha1 uses the "commit-diff" logic that compares against
its parent(s).
This patch adds a framework and a stub implementation of rename
detection to diff-helper program.
The current stub code is just enough to detect pure renames in
diff-tree output and not fancier. The plan is perhaps to use
the same delta code when Nico's delta storage patch is merged
for similarity evaluation purposes.

We already had that as separate logic in git-prune-script, so this

fsck, making normal usage be much simpler.
