This fixes an error introduced to git-apply-patch-script in the previous
round. We do not invoke patch for create/delete case, so we need to
be a bit careful about detecting conflicts like this.

(slightly updated from the version posted to the GIT mailing list
with small bugfixes).
This patch changes the git-apply-patch-script to exit non-zero when
the patch cannot be applied. Previously, the external diff driver
deliberately ignored the exit status of GIT_EXTERNAL_DIFF command,
which was a design mistake. It now stops the processing when
GIT_EXTERNAL_DIFF exits non-zero, so the damages from running
git-diff-* with git-apply-patch-script between two wrong trees can be
contained.
The "diff" command line generated by the built-in driver is changed to
always exit 0 in order to match this new behaviour. I know Pasky does
not use GIT_EXTERNAL_DIFF yet, so this change should not break Cogito,
either.

When git-apply-patch-script creates a new file without
executable mode set, a typo caused it not to report that
activity to the user. Also it was mistakenly running
git-update-cache twice for newly created or deleted paths. This
patch fixes these problems.

I said:
- Stop attempting to be compatible with cg-patch, and drop
(mode:XXXXXX) bits from the diff.
- Do keep the /dev/null change for created and deleted case.
- No "Index:" line, no "Mode change:" line, anywhere in the
output. Anything that wants the mode bits and sha1 hash can
do things from GIT_EXTERNAL_DIFF mechanism. Maybe document
suggested usage better.
This adds an example script git-apply-patch-script, that can be
used as the GIT_EXTERNAL_DIFF to apply changes between two trees
directly on the current work tree, like this:
GIT_EXTERNAL_DIFF=git-apply-patch-script git-diff-tree -p <tree> <tree>
