This adds scoring logic to blame_entry to prevent blames on very
trivial chunks (e.g. lots of empty lines, indent followed by a
closing brace) from being passed down to unrelated lines in the
parent.
The current heuristics are quite simple and may need to be
tweaked later, but we need to start somewhere.

Instead of comparing number of lines matched, look at the
matched characters and count alnums, so that we do not pass
blame on not-so-interesting lines, such as an empty line and
a line that is indentation followed by a closing brace.
Add an option --score-debug to show the score of each
blame_entry while we cook this further on the "next" branch.

This patch only adds the streaming capability to index-pack. Although
the code is different it has the exact same functionality as before to
make sure nothing broke.
This is in preparation for receiving packs over the net, parse them on
the fly, fix them up if they are "thin" packs, and keep the resulting
pack instead of exploding it into loose objects. But such functionality
should come separately.
One immediate advantage of this patch is that index-pack can now deal
with packs up to 4GB in size even on 32-bit architectures since the pack
is not entirely mmap()'d all at once anymore.

This completes the initial round of git-pickaxe. In addition to
the detection of line movements we already have, this finds new
lines that were created by moving or cutting-and-pasting lines
from different files in the parent.
With this,
git pickaxe -f -n -C v1.4.0 -- revision.c
finds that a major part of that file actually came from
rev-list.c when Linus split the latter at commit ae563642 and
blames them to earlier commits that touch rev-list.c.

This makes pickaxe more intelligent than the classic blame.
A typical example is a change that moves one static C function
from lower part of the file to upper part of the same file,
because you added a new caller in the middle.
The versions in the parent and the child would look like this:
parent child
A static foo() {
B ...
C }
D A
E B
F C
G D
static foo() { ... call foo();
... E
} F
H G
H
With the classic blame algorithm, we can blame lines A B C D E F
G and H to the parent. The child is guilty of introducing the
line "... call foo();", and the blame is placed on the child.
However, the classic blame algorithm fails to notice that the
implementation of foo() at the top of the file is not new, and
moved from the lower part of the parent.
This commit introduces detection of such line movements, and
correctly blames the lines that were simply moved in the file to
the parent.

Currently it does what git-blame does, but only faster.
More importantly, its internal structure is designed to support
content movement (aka cut-and-paste) more easily by allowing

inflating 64 bytes is way overkill. Limit it to 20 bytes instead which
should be plenty enough for a couple years to come.

The "union delta_base" is a strange beast. It is a 20-byte
binary blob key to search a binary searchable deltas[] array,
each element of which uses it to represent its base object with
either a full 20-byte SHA-1 or an offset in the pack. Which
representation is used is determined by another field of the
deltas[] array element, obj->type, so there is no room for
confusion, as long as we make sure we compare the keys for the
same type only with appropriate length. The code compared the
full union with memcmp().
When storing the in-pack offset, the union was first cleared
before storing an unsigned long, so comparison worked fine.
On 64-bit architectures, however, the union typically is 24-byte
long; the code did not clear the remaining 4-byte alignment
padding when storing a full 20-byte SHA-1 representation. Using
memcmp() to compare the whole union was wrong.
This fixes the comparison to look at the first 20-bytes of the
union, regardless of the architecture. As long as ulong is
smaller than 20-bytes this works fine.

This was because the hash function used in the library is broken

In a busy project, reverting a commit almost always results
in a conflict between one or more files (depending on the
commit being reverted). It is useful to record this
conflict in the commit-to-be message of the resulting commit
(after the resolve). The process now becomes:
git-revert <SHA-1>
<git complains and prints failed automatic>
<user manually resolves>
git-update-index <resolved files>
git-commit -s
And the commit message is now a merge of the revert commit
message and the conflict commit message, giving the user a
chance to edit it or add more information:

the repository argument for git-clone should be relative to $PWD
instead of the given target directory. The old behavior gave us
surprising success and you need a few minute to know why it worked.
GIT_DIR is already exported so no need to cd into $D. And this makes
$PWD for git-fetch-pack, which is the actual command to take the given

apply_textdelta and send_stream can use a separate pool from the
