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 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
more than one paths to be taken from the same commit.

Supposing that both the base and result sizes were both full size 64-bit

inflating 64 bytes is way overkill. Limit it to 20 bytes instead which

Jim Mayering noticed that xdiff library took insanely long time
when comparing files with many identical lines.
This was because the hash function used in the library is broken
on 64-bit architectures and caused too many collisions.

This reverts commit 16854571aa.
Git as recent as v1.1.6 do not understand version 3 delta.
v1.2.0 is Ok and I personally would say it is old enough, but
the improvement between version 2 and version 3 delta is not
bit enough to justify breaking older clients.
We should resurrect this later, but when we do so we shold
make it conditional.

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
repository dir, the same as git-clone.

apply_textdelta and send_stream can use a separate pool from the
rest of the editor interface, so we'll use a separate SVN::Pool
for them and clear the pool after each file is sent to SVN.
This drastically reduces memory usage per-changeset committed,
and makes large commits (and initial imports) of several

Once a get_commit_editor has been called from an SVN session, RA
layer operations are not allowed (well, unless you're using
file:// or http(s)://). So we'll pass an alternate SVN::Ra
object to our editor object for running 'check-path'.
This should fix commits over svnserve (svn:// without ssh, too).

I'm using svn 1.4.0-4 in Debian unstable and apparently there's
a regression on the SVN side that prevents a symlink from
becoming a regular file (which git supports, of course).
It's not a noticeable regression for most people, but this broke
the full-svn-tests target in t/Makefile for me.
The SVN::* Perl libraries seem to have matured and improved over
the past year, and git-svn has supported them for several months
now, so with that I encourage all users to start using the
SVN::* Perl libraries with git-svn.
