redo log record.

of collation order.

and increment n_blobs for records that have not been deleted.
page_zip_clear_rec(): Clear trx_id and roll_ptr on the compressed page.
page_zip_dir_delete(): Decrement PAGE_N_RECS. Shift the array of

space of roll_ptr and trx_id.
page_cur_delete_rec(): Do not decrement PAGE_N_RECS or call
page_zip_clear_rec(), as page_mem_free() already does it.

page_mem_free(): Remove parameter mtr. Do not call page_zip_clear_rec() here.
page_cur_delete_rec(): Call page_zip_clear_rec() here. Decrement PAGE_N_RECS
only after calling page_mem_free(). Assert page_zip_validate().
btr_root_raise_and_insert(): Because btr_page_set_level() must not
change level from non-zero to zero on compressed pages, invoke
btr_page_set_level() with page_zip==NULL and compress the entire
root page after creating it from the scratch.
btr_attach_half_pages(): Simplify the computation of lower_page_zip
and upper_page_zip. Invoke btr_node_ptr_set_child_page_no() with
the correct page_zip.

page_cur_search_with_match(): Make use of page_is_leaf().
page_dir_add_slots(): Replaced with page_dir_add_slot(). Use memmove().
do not allow extra_size to decrease on compressed pages.
Split page_mem_alloc() to page_mem_alloc_free() and page_mem_alloc_heap().

logic from page_mem_alloc().
page_cur_tuple_insert(): Convert the tuple to a record and calculate offsets.
page_zip_validate(): Assert that the page is in compact format.
BLOB pointers, trx_id, and roll_ptr.
btr_empty(), btr_create(), page_create(): Add parameter "index", as some
index information will be encoded on the compressed page.
Define REC_NODE_PTR_SIZE as 4.
Allow btr_page_reorganize() and btr_page_reorganize_low() to fail.
Define the error code DB_ZIP_OVERFLOW.
Make row_ins_index_entry_low() static.
page0zip: Encode the index, log reorganized records, and store uncompressed
fields separately from the compressed data stream.
page_set_max_trx_id(), page_update_max_trx_id(): Add parameter page_zip.
Check that page_zip_decompress() is never called after modifying the
header or trailer of the compressed page, i.e., that page_zip_decompress()
will restore the uncompressed page as it was before the failed operation.

page_dir_delete_slot(): Fix off-by-one errors.
