[libgit2-glib/wip/maxice8/fix-new-libgit2-api: 1/2] Compatibility with libgit2 0.28

[Alberto Fanjul <albfan src gnome org>]

commit d1a6cf1cebcbcde518dc1a485e99e43375fb000b

    Compatibility with libgit2 0.28
    
    The git_buf_free API is deprecated; it has been renamed to
      git_buf_dispose for consistency.  The git_buf_free API will be
      retained for backward compatibility for the foreseeable future.
    
    The error functions and enumeration values have been renamed for
      consistency.  The giterr_ functions and values prefix have been
      renamed to be prefixed with git_error_; similarly, the GITERR_
      constants have been renamed to be prefixed with GIT_ERROR_.
      The old enumerations and macros will be retained for backward
      compatibility for the foreseeable future.
