Now we use a simple closed-addressing cache. Cuckoo hashing was creating
too many issues with race conditions. Fuck that.

Let's see what happens performance wise, we may have to roll back or
come up with another way to implement an efficient multi-threaded cache.

Do not try to adquire the same node lock twice when the cuckoo hashing
resolves to the same node.

Fix a typo in README.md

This is not really an error, just a special return code to mark the end
of an iteration.

Updated fileops.c and repository.c to new error handling mechanism

fix git_otype typo when calling `git_odb_read_header`.

Replace errors

Add --with-redis flag to list of available build flags in README.

Hey, welcome to yet another minor libgit2 release. Sorry for the delay from
the last one. As you'll see the changelog is quite extensive -- hopefully from
now on we'll stick to more frequent minor releases.

Together with the usual bugfixes, here's a list of the new key features:

* Distfiles

	This version comes with proper distfiles as requested in #131. These are
	available in the Downloads section of the GitHub project.

* Error handling

	A new error handling API has been implemented that allows the library to
	return detailed error messages together with the generic error codes. We
	hope this will be a great when wrapping and integrating the library

	New external method to get the last detailed error message:

		+ git_lasterror(void)

	The old `git_strerror` still exists, but will be deprecated in the future
	as soon as every method in the library returns a valid error message.

	The task of writing error messages for every method is quite daunting.
	We appreciate pull requests with more error messages. Check the new error
	handling documentation in the following commit:

	https://github.com/libgit2/libgit2/commit/fa59f18d0ddbbb98d45e33934fb0efc3e2bf1557

* Redis backend

	We now have a Redis backend courtesy of Dmitry Kovega. Just like the
	SQLite backend, this allows the library to store Git objects in a Redis
	key-value store.

	The backend requires the `hiredis` library. Use `--with-redis` when
	building libgit2 to enable building the backend if `hiredis` is available.

* Commits

	New methods to access tree and parent data as a raw OID value
	instead of forcing a repository lookup

		+ git_commit_tree_oid(git_commit *commit)
		+ git_commit_parent_oid(git_commit *commit, unsigned int n)

* Index

	The `git_index_add` method has been split into 4 different calls
	which allow for appending and replacing in-memory entries and on-disk
	files to the index.

		+ git_index_add(git_index *index, const char *path, int stage)
		+ git_index_add2(git_index *index, const git_index_entry *source_entry)
		+ git_index_append(git_index *index, const char *path, int stage)
		+ git_index_append2(git_index *index, const git_index_entry *source_entry)

	Index entries can now also be efficiently removed from the index:

		+ git_index_remove(git_index *index, int position)

* References

	Methods to force the creation and renaming of references, even if those already
	exist on the repository.

		+ git_reference_create_symbolic_f(git_reference **ref_out, git_repository *repo,
				const char *name, const char *target)
		+ git_reference_create_oid_f(git_reference **ref_out, git_repository *repo,
				const char *name, const git_oid *id)
		+ git_reference_rename_f(git_reference *ref, const char *new_name)

* Repository

	New auxiliary methods with repository information

		+ git_repository_is_empty(git_repository *repo)
		+ git_repository_path(git_repository *repo)
		+ git_repository_workdir(git_repository *repo)

* Signatures

	New method to create a signature with the current date/time

		+ git_signature_now(const char *name, const char *email)

* Tags

	Several wrappers to automate tag creation.

		+ git_tag_create_frombuffer(git_oid *oid, git_repository *repo,
				const char *buffer)
		+ git_tag_create_f(git_oid *oid, git_repository *repo,
				const char *tag_name, const git_oid *target,
				git_otype target_type, const git_signature *tagger,
				const char *message);
		+ git_tag_create_fo(git_oid *oid, git_repository *repo,
				const char *tag_name, const git_object *target,
				const git_signature *tagger, const char *message)

	New functionality to delete and list tags in a repository without
	having to resort to the `references` API.

		+ git_tag_delete(git_repository *repo, const char *tag_name)

		+ git_tag_list(git_strarray *tag_names, git_repository *repo)

* Trees

	All instances of `git_tree_entry` are now returned and handled
	as constant, to remind the user that these opaque types are not
	supposed to be manually free'd.

	The `git_tree_entry_2object` method now takes a `git_repository`
	argument which defines in which repository the resolved object
	should be looked up. (It is expected to be the same repository
	that contains the parent `git_tree` for the entry).

		+ git_tree_entry_2object(git_object **object_out, git_repository *repo,
				const git_tree_entry *entry)

	New opaque type `git_treebuilder` with functionality to create and
	write trees on memory

		+ git_treebuilder_create(git_treebuilder **builder_p, const git_tree *source)
		+ git_treebuilder_clear(git_treebuilder *bld)
		+ git_treebuilder_free(git_treebuilder *bld)
		+ git_treebuilder_get(git_treebuilder *bld, const char *filename)
		+ git_treebuilder_insert(git_tree_entry **entry_out, git_treebuilder *bld,
				const char *filename, const git_oid *id, unsigned int attributes)
		+ git_treebuilder_remove(git_treebuilder *bld, const char *filename)
		+ git_treebuilder_filter(git_treebuilder *bld,
				int (*filter)(const git_tree_entry *, void *), void *payload)
		+ git_treebuilder_write(git_oid *oid, git_repository *repo, git_treebuilder *bld)

	New method to write an index file as a tree to the ODB.

		+ git_tree_create_fromindex(git_oid *oid, git_index *index)

Thanks to the usual guility parties that make this this happen, to
all the new contributors who are starting to submit pull requests, and
to the bindings developers who have to keep up with our shit.

We cannot totally deprecate this until the new error handling mechanisms
are all in place.

Fix issue #79 - git_lasterror() isn't appearing in git2.dll in windows.

Move signature.c and tag.c to the new error handling

Configuration options can come from different sources. Currently,
there is only support for reading them from a flat file, but it might
make sense to read it from a database at some point.

Move the parsing code into src/config_file.c and create an include
file include/git2/config_backend.h to allow for other backends to be
developed.

The GIT_EXPORT macro is used to declare a function to be externally
accessible to other libraries.  This commit uses GIT_EXPORT to declare
the git_lasterror() function as externally exported.  I verified with
depends.exe that the function is available to external callers (i.e.
in the exports table of the PE file).
