This changes the link detection logic to accept strings of between 6
and 40 hex characters as a possible SHA1 ID of another commit, rather
than insisting on seeing the full 40 hex characters.
To make the logic that turns a possible link into an actual link work
with abbreviated IDs, this changes the way the commitinterest array is
used, and puts the code that deals with it in a pair of new functions.
The commitinterest array is now indexed by just the first 4 characters
of the interesting SHA1 ID, and each element is a list of id + command
pairs. This also pulls out the logic for expanding an abbreviated
SHA1 to the list of matching full IDs into its own function (the way
it is done is still the same slow way it was done before, which should
be improved some day).
This also fixes the bug where clicking on a link would take you to the
wrong commit if the line number of the target had changed since the
link was made.
This is based on a patch by Linus Torvalds, but totally rewritten by me.

Since commit 9441b61dc5, two issues affected correct behavior of
index-pack:
1) The real_type of a delta object is the 'real_type' of its base, not
the 'type' which can be a "delta type". Consequence of this is a
corrupted pack index file which only needs to be recreated with a
good index-pack command ('git verify-pack' will flag those).
2) The code sequence:
result->data = patch_delta(get_base_data(base), base->obj->size,
delta_data, delta_size, &result->size);
has two issues of its own since base->obj->size should instead be
base->size as we want the size of the actual object data and not
the size of the delta object it is represented by. Except that
simply replacing base->obj->size with base->size won't make the
code more correct as the C language doesn't enforce a particular
ordering for the evaluation of needed arguments for a function call,
hence base->size could be pushed on the stack before get_base_data()
which initializes base->size is called.

06cbe855 (Make core.sharedRepository more generic, 2008-04-16) made
several testcases in t1301-shared-repo.sh which fail if on a system
which creates files with extended attributes (e.g. SELinux), since ls
appends a '+' sign to the permission set in such cases. In fact,
POSIX.1 allows ls to add a single printable character after the usual
3x3 permission bits to show that an optional alternate/additional access
method is associated with the path.
This fixes the testcase to strip any such sign prior to verifying the
permission set.

When diffing binary files, it is sometimes nice to see the
differences of a canonical text form rather than either a
binary patch or simply "binary files differ."
Until now, the only option for doing this was to define an
external diff command to perform the diff. This was a lot of
work, since the external command needed to take care of
doing the diff itself (including mode changes), and lost the
benefit of git's colorization and other options.
This patch adds a text conversion option, which converts a
file to its canonical format before performing the diff.
This is less flexible than an arbitrary external diff, but
is much less work to set up. For example:
$ echo '*.jpg diff=exif' >>.gitattributes
$ git config diff.exif.textconv exiftool
$ git config diff.exif.binary false
allows one to see jpg diffs represented by the text output
of exiftool.

The "diff" gitattribute is somewhat overloaded right now. It
can say one of three things:
1. this file is definitely binary, or definitely not
(i.e., diff or !diff)
2. this file should use an external diff engine (i.e.,
diff=foo, diff.foo.command = custom-script)
3. this file should use particular funcname patterns
(i.e., diff=foo, diff.foo.(x?)funcname = some-regex)
Most of the time, there is no conflict between these uses,
since using one implies that the other is irrelevant (e.g.,
an external diff engine will decide for itself whether the
file is binary).
However, there is at least one conflicting situation: there
is no way to say "use the regular rules to determine whether
this file is binary, but if we do diff it textually, use
this funcname pattern." That is, currently setting diff=foo
indicates that the file is definitely text.
This patch introduces a "binary" config option for a diff
driver, so that one can explicitly set diff.foo.binary. We
default this value to "don't know". That is, setting a diff
attribute to "foo" and using "diff.foo.funcname" will have
no effect on the binaryness of a file. To get the current
behavior, one can set diff.foo.binary to true.
This patch also has one additional advantage: it cleans up
the interface to the userdiff code a bit. Before, calling
code had to know more about whether attributes were false,
true, or unset to determine binaryness. Now that binaryness
is a property of a driver, we can represent these situations
just by passing back a driver struct.

Both sets of code assume that one specifies a diff profile
as a gitattribute via the "diff=foo" attribute. They then
pull information about that profile from the config as
diff.foo.*.
The code for each is currently completely separate from the
other, which has several disadvantages:
- there is duplication as we maintain code to create and
search the separate lists of external drivers and
funcname patterns
- it is difficult to add new profile options, since it is
unclear where they should go
- the code is difficult to follow, as we rely on the
"check if this file is binary" code to find the funcname
pattern as a side effect. This is the first step in
refactoring the binary-checking code.
This patch factors out these diff profiles into "userdiff"
drivers. A file with "diff=foo" uses the "foo" driver, which
is specified by a single struct.
Note that one major difference between the two pieces of
code is that the funcname patterns are always loaded,
whereas external drivers are loaded only for the "git diff"
porcelain; the new code takes care to retain that situation.

format-patch is most commonly used for multiple patches at once when
sending a patchset, in which case we want to number the patches; on
the other hand, single patches are not usually expected to be
numbered.
In other words, the typical behavior expected from format-patch is the
one obtained by enabling autonumber, so we set it to be the default.
Users that want to disable numbering for a particular patchset can do
so with the existing -N command-line switch. Users that want to
change the default behavior can use the format.numbering config key.

When the "git status" display code was originally converted
to C, we copied the code from ls-files to discover whether a
pathname returned by read_directory was an "other", or
untracked, file.
Much later, 5698454e updated the code in ls-files to handle
some new cases caused by gitlinks. This left the code in
wt-status.c broken: it would display submodule directories
as untracked directories. Nobody noticed until now, however,
because unless status.showUntrackedFiles was set to "all",
submodule directories were not actually reported by
read_directory. So the bug was only triggered in the
presence of a submodule _and_ this config option.
This patch pulls the ls-files code into a new function,
cache_name_is_other, and uses it in both places. This should
leave the ls-files functionality the same and fix the bug
in status.
