fsp_page_create(): Always initialize the page. The logic to
avoid initialization was made redundant and should have been removed
in mysql/mysql-server@ce0a1e85e24e48b8171f767b44330da635a6ea0a
(MySQL 5.7.5).
btr_store_big_rec_extern_fields(): Remove the redundant initialization
of FIL_PAGE_PREV and FIL_PAGE_NEXT. An INIT_PAGE record will have
been written already. Only write the ROW_FORMAT=COMPRESSED page payload
from FIL_PAGE_DATA onwards. We were unnecessarily writing from
FIL_PAGE_TYPE onwards, which caused an assertion failure on recovery:
page_update_max_trx_id(), page_delete_rec_list_end(): Remove conditions
on recv_recovery_is_on(). These conditions should have been removed in
or before commit f8a9f906679e1d1ab026c245f7d24c652050d8b3
(removing the support for crash-upgrade).
The physical redo log based recovery will not call such high-level code.
page_mem_free(): When deleting the last record of a page,
do not add it to the PAGE_FREE list, but instead truncate the
PAGE_HEAP_TOP. Modify the page header fields by writing fewer
records.
page_cur_delete_rec(): Let page_mem_free() reset the PAGE_LAST_INSERT.
page_header_reset_last_insert(): Issue memset(), not memcpy(), for
the ROW_FORMAT=COMPRESSED page.
