indexer: properly free the packfile resources
The indexer needs to call the packfile's free function so it takes care of
freeing the caches.
We still need to close the mwf descriptor manually so we can rename the
packfile into its final name on Windows.

Revert "pack: packfile_free -> git_packfile_free and use it in the indexers"
This reverts commit f289f886cb81bb570bed747053d5ebf8aba6bef7, which
makes the tests fail on Windows. Revert until we can figure out a
solution.

pack: introduce a delta base cache
Many delta bases are re-used. Cache them to avoid inflating the same
data repeatedly.
This version doesn't limit the amount of entries to store, so it can
end up using a considerable amound of memory.

pack: add git_packfile_resolve_header
To paraphrase @peff:
You can get both size and type from a packed object reasonably cheaply.
If you have:
* An object that is not a delta; both type and size are available in the
packfile header.
* An object that is a delta. The packfile type will be OBJ_*_DELTA, and
you have to resolve back to the base to find the real type. That means
potentially a lot of packfile index lookups, but each one is
relatively cheap. For the size, you inflate the first few bytes of the
delta, whose header will tell you the resulting size of applying the
delta to the base.
For simplicity, we just decompress the whole delta for now.

pack: introduce a streaming API for raw objects
This allows us to take objects from the packfile as a stream instead
of having to keep it all in memory.

Make git_odb_foreach_cb take const param
This makes the first OID param of the ODB callback a const pointer
and also propogates that change all the way to the backends.

Migrate ODB files to new error handling
This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to
the new style of error handling. Also got the unix and win32
versions of map.c. There are some minor changes to other
files but no others were completely converted.
This also contains an update to filebuf so that a zeroed out
filebuf will not think that the fd (== 0) is actually open
(and inadvertently call close() on fd 0 if cleaned up).
Lastly, this was built and tested on win32 and contains a
bunch of fixes for the win32 build which was pretty broken.

*: correct and codify various file permissions
The following files now have 0444 permissions:
- loose objects
- pack indexes
- pack files
- packs downloaded by fetch
- packs downloaded by the HTTP transport
And the following files now have 0666 permissions:
- config files
- repository indexes
- reflogs
- refs
This brings libgit2 more in line with Git.
Note that git_filebuf_commit() and git_filebuf_commit_at() have both
gained a new mode parameter.
The latter change fixes an important issue where filebufs created with
GIT_FILEBUF_TEMPORARY received 0600 permissions (due to mkstemp(3)
usage). Now we chmod() the file before renaming it into place.
Tests have been added to confirm that new commit, tag, and tree
objects are created with the right permissions. I don't have access to
Windows, so for now I've guarded the tests with "#ifndef GIT_WIN32".

Tabify everything
There were quite a few places were spaces were being used instead of
tabs. Try to catch them all. This should hopefully not break anything.
Except for `git blame`. Oh well.

Cleanup legal data
1. The license header is technically not valid if it doesn't have a
copyright signature.
2. The COPYING file has been updated with the different licenses used in
the project.
3. The full GPLv2 header in each file annoys me.

Implement cooperative caching
When indexing a file with ref deltas, a temporary cache for the
offsets has to be built, as we don't have an index file yet. If the
user takes the responsiblity for filling the cache, the packing code
will look there first when it finds a ref delta.

Modify the given offset in git_packfile_unpack
The callers immediately throw away the offset, so we don't need any
logical changes in any of them. This will be useful for the indexer,
as it does need to know where the compressed data ends.
