(init_buffer_once): Adjusted for the above change.

(syms_of_buffer): Declarations of Lisp variables
default-direction-reversed and direction_reversed are deleted.
New declarations for Lisp vairables default-orientation-reversed
and default-enable-bidi-display, orientation_reversed,
enable_bidi_display.
