* This allows KPath to not allocate a buffer when initialized without path. * Added test cases for this. * Added test for LockBuffer(). * Enhanced tests to allow building them in debug mode. * Moved calling vfs_normalize_path() into own private method. * Improved error codes; B_NO_MEMORY is now only returned if the allocation actually failed. * If used with LAZY_ALLOC, Path() and LockBuffer() are now allowed to return a NULL path.
