Martin Koegler b41860bf28 unpack-objects: prevent writing of inconsistent objects
This patch introduces a strict mode, which ensures that:
- no malformed object will be written
- no object with broken links will be written

The patch ensures this by delaying the write of all non blob object.
These object are written, after all objects they link to are written.

An error can only result in unreferenced objects.

=====================
NAME
----
git-unpack-objects - Unpack objects from a packed archive
SYNOPSIS
--------
'git-unpack-objects' [-n] [-q] [-r] <pack-file
DESCRIPTION
-----------
Read a packed archive (.pack) from the standard input, expanding
the objects contained within and writing them into the repository in
"loose" (one object per file) format.
Objects that already exist in the repository will *not* be unpacked
from the pack-file. Therefore, nothing will be unpacked if you use
this command on a pack-file that exists within the target repository.
Please see the `git-repack` documentation for options to generate
new packs and replace existing ones.
OPTIONS
-------
-n::
Dry run. Check the pack file without actually unpacking
the objects.
-q::
The command usually shows percentage progress. This
flag suppresses it.
-r::
When unpacking a corrupt packfile, the command dies at
the first corruption. This flag tells it to keep going
and make the best effort to recover as many objects as
possible.
--strict::
Don't write objects with broken content or links.
