Options

(Fmake_indirect_buffer): Use set_marker_both. 

(set_buffer_internal_1): Likewise.
(set_buffer_temp): Likewise.

(set_buffer_temp): Update BUF_PT_BYTE, BUF_BEGV_BYTE and BUF_ZV_BYTE.
(Fmake_indirect_buffer, set_buffer_internal_1):
Set up the pt, begv and zv markers with both kinds of position.
Set BUF_PT_BYTE, BUF_BEGV_BYTE, BUF_ZV_BYTE.
(Fget_buffer_create): Set BUF_..._BYTE.
