A bunch of redundant methods have been removed from the external API.

- All the reference/tag creation methods with `_f` are gone. The force
flag is now passed as an argument to the normal create methods.

- All the different commit creation methods are gone; commit creation
now always requires a `git_commit` pointer for parents and a `git_tree`
pointer for tree, to ensure that corrupted commits cannot be generated.

- All the different tag creation methods are gone; tag creation now
always requires a `git_object` pointer to ensure that tags are not
created to inexisting objects.

gitfo_read: fix read-loop

Two memory access fixes

Call gitfo_lstat with the full pathname instead of the relative one,
which fails in case the current working directory is different from
the workdir.

Also allow space for the null-terminator when allocating the buffer in
packfile_unpack_compressed. Up to now, the last newline had served as
a terminator, but 858ef372 searches for a double-newline and exposes
the problem.

On this rascalicious minor release of libgit2:

- We've dropped support for Waf. All the build process is now managed
through CMake for all platforms.

- We've removed the custom backends from the repository. You can now
find a collection of Custom backends on their own repo, under the
libgit2 org. Including MySQL and Memcache backends, courtesy of the
beardful Brian Lopez.

- We are rocking a new documentation system, Docurium, courtesy of the
insightful Scott Chacon. Check out the details for each single method
in our external API and the way they've evolved through the history
of the library:

	http://libgit2.github.com/libgit2/

This will certainly come in handy if you are developing bindings for
the library.

- You can now check the linked version of the library from your
application or bindings, using `git_libgit2_version`.

- We have a gazillion new features, courtesy of our invaluable
collaborators, including:

	* Support for Config files!
	* Support for prefix-only reads on the ODB
	* Repository discovery
	* Support for the Unmerged Entries index extension
	* Better Windows support
	* 30.000 bug fixes (actual number may be lower)

Thanks as always to everyone who makes this project possible.

Here's the full list of all external API changes:

- git_index_open_inrepo
- git_odb_backend_sqlite
- git_oid_mkraw
- git_oid_mkstr
- git_reference_listcb

Do not mess with environment variables anymore. The new external API has
more helper methods, and everything is explicit.

If a config has several files, we need to check all of them before we
can say that a variable doesn't exist.

The repo's configuration should take precedence over the global one.

Signed-off-by: Carlos Martín Nieto <cmn@elego.de>

It's not enough to load the config, we also need to explicitely parse
it after we create it.

This function puts the global and repository configurations in one
git_config object and gives it to the user.

Runtime checks are asserting on the embedded ZLib code because of
truncation (see zlib/trees.c:218). This is not good or pretty, but I'm
wary about patching the ZLib code even more.

There are two ways to fix this:

	- Patch the ZLib code, and start storing a diff/patchset on
	how does our version of ZLib differ from the original one, so we can
	be more or less on sync when new version of ZLib.

	- Go back to ZLib as an external dependency, which is np for *NIX
	users but annoying as dicks for Windows users.
