  Added function-based initializers for every options struct. The basic structure of each function is courtesy of arrbee.

  /* Checks two conditions for the specified structure:
   *     1. That the initializers for the latest version produces the same
   *        in-memory representation.
   *     2. That the function-based initializer supports all versions from 1...n,
   *        where n is the latest version (often represented by GIT_*_VERSION).
   *
   * Parameters:
   *     structname: The name of the structure to test, e.g. git_blame_options.
   *     structver: The latest version of the specified structure.
   *     macroinit: The macro that initializes the latest version of the structure.
   *     funcinitname: The function that initializes the structure. Must have the
   *                   signature "int (structname* instance, int version)".
