branches/zip: Remove the fil_space_get_zip_size() call from buf_page_get_gen(). This saves one mutex operation per block request. buf_page_get_gen(), various macros and functions: Add parameter zip_size. btr_node_ptr_get_child(): Add parameter index. fil_space_get_latch(): Add optional output parameter zip_size. fil_space_get_zip_size(): Return 0 for space id==0, because the system tablespace is never compressed. fsp_header_init(): Remove the parameter zip_size. ibuf_free_excess_pages(): Remove the parameter zip_size. trx_rseg_t, trx_undo_t: Add field zip_size. xdes_lst_get_next(): Remove, unused.
