This update addresses all of the feedback in pull request #570.
The biggest change was to create actual linked list stacks for
storing the tree and workdir iterator state. This cleaned up
the code a ton. Additionally, all of the static functions had
their 'git_' prefix removed, and a lot of other unnecessary
changes were removed from the original patch.
This create a new git_iterator type of object that provides a
uniform interface for iterating over the index, an arbitrary
tree, or the working directory of a repository.
As part of this, git ignore support was extended to support
push and pop of directory-based ignore files as the working
directory is being traversed (so the array of ignores does
not have to be recreated at each directory during traveral).
There are a number of other small utility functions in buffer,
path, vector, and fileops that are included in this patch
that made the iterator implementation cleaner.
This updates to implementation of gitattribute macros to be much more
similar to core git (albeit not 100%) and to handle expansion of
macros within macros, etc. It also cleans up the refcounting usage
with macros to be much cleaner.
Also, this adds a new vector function `git_vector_insert_sorted()`
which allows you to maintain a sorted list as you go. In order to
write that function, this changes the function `git__bsearch()` to
take a somewhat different set of parameters, although the core
functionality is still the same.
This adds APIs for querying git attributes. In addition to
the new API in include/git2/attr.h, most of the action is in
src/attr_file.[hc] which contains utilities for dealing with
a single attributes file, and src/attr.[hc] which contains
the implementation of the APIs that merge all applicable
attributes files.
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.
The routine remove duplictes from the vector. Only the last added element
of elements with equal keys remains in the vector.

We now store only one sorting callback that does entry comparison. This
is used when sorting the entries using a quicksort, and when looking for
a specific entry with the new search methods.
The following search methods now exist:
git_vector_search(vector, entry)
git_vector_search2(vector, custom_search_callback, key)
git_vector_bsearch(vector, entry)
git_vector_bsearch2(vector, custom_search_callback, key)
The sorting state of the vector is now stored internally.

These two reference types are now stored separately to eventually allow
the removal/renaming of loose references and rewriting of the refs
packfile.

Libgit2 is now officially include as
#include "<git2.h>"
or indidividual files may be included as
#include <git2/index.h>

All the operations on the 'git_index_entry' array and the
'git_tree_entry' array have been refactored into common code in the
src/vector.c file.
The new vector methods support:
- insertion: O(1) (avg)
- deletion: O(n)
- searching: O(logn)
- sorting: O(logn)
- r. access: O(1)
