This option is known to be broken when tablespaces contain off-page
columns after crash recovery. It has only been tested when creating
the data files from the scratch.
btr_blob_dbg_t: A map from page_no:heap_no:field_no to first_blob_page_no.
This map is instantiated for every clustered index in index->blobs.
It is protected by index->blobs_mutex.
btr_blob_dbg_msg_issue(): Issue a diagnostic message.
Invoked when btr_blob_dbg_msg is set.
btr_blob_dbg_rbt_insert(): Insert a btr_blob_dbg_t into index->blobs.
btr_blob_dbg_rbt_delete(): Remove a btr_blob_dbg_t from index->blobs.
btr_blob_dbg_cmp(): Comparator for btr_blob_dbg_t.
btr_blob_dbg_add_blob(): Add a BLOB reference to the map.
btr_blob_dbg_add_rec(): Add all BLOB references from a record to the map.
btr_blob_dbg_print(): Display the map of BLOB references in an index.
btr_blob_dbg_remove_rec(): Remove all BLOB references of a record from
the map.
btr_blob_dbg_is_empty(): Check that no BLOB references exist to or
from a page. Disowned references from delete-marked records are
tolerated.
btr_blob_dbg_op(): Perform an operation on all BLOB references on a
B-tree page.
btr_blob_dbg_add(): Add all BLOB references from a B-tree page to the
map.
btr_blob_dbg_remove(): Remove all BLOB references from a B-tree page
from the map.
btr_blob_dbg_restore(): Restore the BLOB references after a failed
page reorganize.
btr_blob_dbg_set_deleted_flag(): Modify the 'deleted' flag in the BLOB
references of a record.
btr_blob_dbg_owner(): Own or disown a BLOB reference.
btr_page_create(), btr_page_free_low(): Assert that no BLOB references exist.
btr_create(): Create index->blobs for clustered indexes.
btr_page_reorganize_low(): Invoke btr_blob_dbg_remove() before copying
the records. Invoke btr_blob_dbg_restore() if the operation fails.
btr_page_empty(), btr_lift_page_up(), btr_compress(), btr_discard_page():
Invoke btr_blob_dbg_remove().
btr_cur_del_mark_set_clust_rec(): Invoke btr_blob_dbg_set_deleted_flag().
Other cases of modifying the delete mark are either in the secondary
index or during crash recovery, which we do not promise to support.
btr_cur_set_ownership_of_extern_field(): Invoke btr_blob_dbg_owner().
btr_store_big_rec_extern_fields(): Invoke btr_blob_dbg_add_blob().
btr_free_externally_stored_field(): Invoke btr_blob_dbg_assert_empty()
on the first BLOB page.
page_cur_insert_rec_low(), page_cur_insert_rec_zip(),
page_copy_rec_list_end_to_created_page(): Invoke btr_blob_dbg_add_rec().
page_cur_insert_rec_zip_reorg(), page_copy_rec_list_end(),
page_copy_rec_list_start(): After failure, invoke
btr_blob_dbg_remove() and btr_blob_dbg_add().
page_cur_delete_rec(): Invoke btr_blob_dbg_remove_rec().
page_delete_rec_list_end(): Invoke btr_blob_dbg_op(btr_blob_dbg_remove_rec).
page_zip_reorganize(): Invoke btr_blob_dbg_remove() before copying the records.
page_zip_copy_recs(): Invoke btr_blob_dbg_add().
row_upd_rec_in_place(): Invoke btr_blob_dbg_rbt_delete() and
btr_blob_dbg_rbt_insert().
innobase_start_or_create_for_mysql(): Warn when UNIV_BLOB_DEBUG is enabled.

when renaming tables
Allocate the table name using ut_malloc() instead of table->heap because
the latter cannot be freed.
Adjust dict_sys->size calculations all over the code.
Change dict_table_t::name from const char* to char* because we need to
ut_malloc()/ut_free() it.

branches/zip: Suppress errors about non-found temporary tables.
Write the is_temp flag to SYS_TABLES.MIX_LEN.
dict_table_t:🎏 Add a flag for is_temporary, DICT_TF2_TEMPORARY.
Unlike other flags, this will not be written to the tablespace flags
or SYS_TABLES.TYPE, but only to SYS_TABLES.MIX_LEN.
dict_build_table_def_step(): Only pass DICT_TF_BITS to tablespaces.
dict_check_tablespaces_and_store_max_id(), dict_load_table():
Suppress errors about temporary tables not being found.
dict_create_sys_tables_tuple(): Write the DICT_TF2_TEMPORARY flag

We only store the autoinc locks that are granted in the transaction's autoinc
lock vector. A transacton, that has been rolled back due to a deadlock because
of an AUTOINC lock attempt, will not have added that lock to the vector. We
need to check for that when we remove that lock.
