  Custom transport: minor cleanups * Move the transport registration mechanisms into a new header under 'sys/' because this is advanced stuff. * Remove the 'priority' argument from the registration as it adds unnecessary complexity. (Since transports cannot decline to operate, only the highest priority transport is ever executed.) Users who require per-priority transports can implement that in their custom transport themselves. * Simplify registration further by taking a scheme (eg "http") instead of a prefix (eg "http://").

  /* 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)".
