This commit adds basic git notes support to libgit2, namely:
* git_note_read
* git_note_message
* git_note_oid
* git_note_create
* git_note_remove
In the long run, we probably want to provide some convenience callback
mechanism for merging and moving (filter-branch) notes.

This is legacy compat stuff for when `deflateBound` is not defined, but
we're not embedding zlib and that function is always available. Kill
that with fire.
git_commit_create is supposed to update the given reference
"update_ref", but segfaulted in case of a yet to be born
reference. Fix it.

This lovely and much delayed release of libgit2 ships from the cold city
of Brussels, which is currently hosting FOSDEM 2012.
There's been plenty of changes since the latest stable release, here's a
full summary:
- Git Attributes support (see git2/attr.h)
There is now support to efficiently parse and retrieve information
from `.gitattribute` files in a repository. Note that this
information is not yet used e.g. when checking out files.
- .gitignore support
Likewise, all the operations that are affected by `.gitignore` files
now take into account the global, user and local ignores when
skipping the relevant files.
- Cleanup of the object ownership semantics
The ownership semantics for all repository subparts (index, odb,
config files, etc) has been redesigned. All these objects are now
reference counted, and can be hot-swapped in the middle of
execution, allowing for instance to add a working directory and an
index to a repository that was previously opened as bare, or to
change the source of the ODB objects after initialization.
Consequently, the repository API has been simplified to remove all
the `_openX` calls that allowed setting these subparts *before*
initialization.
- git_index_read_tree()
Git trees can now be read into the index.
- More reflog functionality
The reference log has been optimized, and new API calls to rename
and delete the logs for a reference have been added.
- Rewrite of the References code with explicit ownership semantics
The references code has been mostly rewritten to take into account
the cases where another Git application was modifying a repository's
references while the Library was running.
References are now explicitly loaded and free'd by the user, and
they may be reloaded in the middle of execution if the user suspects
that their values may have changed on disk. Despite the new
ownership semantics, the references API stays the same.
- Simplified the Remotes API
Some of the more complex Remote calls have been refactored into
higher level ones, to facilitate the usual `fetch` workflow of a
repository.
- Greatly improved thread-safety
The library no longer has race conditions when loading objects from
the same ODB and different threads at the same time. There's now
full TLS support, even for error codes. When the library is built
with `THREADSAFE=1`, the threading support must be globally
initialized before it can be used (see `git_threads_init()`)
- Tree walking API
A new API can recursively traverse trees and subtrees issuing callbacks for
every single entry.
- Tree diff API
There is basic support for diff'ing an index against two trees.
- Improved windows support
The Library is now codepage aware under Windows32: new API calls
allow the user to set the default codepage for the OS in order to
avoid strange Unicode errors.
This fixes an issue which was detected while using one of the libgit2 bindings [0]. The lack of the trailing forward slash led the name of references returned by git_reference_listall() to be prefixed with a forward slash.

Add unit tests to confirm ignore directory pattern matches and
to confirm that ignore and attribute files are loaded properly
into the attribute file cache.
Now that is_dir is calculated correctly for attr/ignore paths,
it is possible to use it so that ignoring "dir/" will properly
match the directory name and ignore the entire directory.
When building an attr path object, the code that checks if the
file is a directory was evaluating the file as a relative path
to the current working directory, instead of using the repo root.
This lead to inconsistent behavior.
git_refspec_transform_r assumed that the reference name passed would
be only a branch or tag name. This is not the case, and we need to
take into consideration what's in the refspec's source to know how
much of the prefix to ignore.
