  Improved gitattributes macro implementation 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.
