This is based on commit 20ae4816bb
with some adjustments for MDEV-12353.
row_ins_sec_index_entry_low(): If a separate mini-transaction is
needed to adjust the minimum bounding rectangle (MBR) in the parent
page, we must disable redo logging if the table is a temporary table.
For temporary tables, no log is supposed to be written, because
the temporary tablespace will be reinitialized on server restart.
rtr_update_mbr_field(), rtr_merge_and_update_mbr(): Changed the return
type to void and removed unreachable code. In older versions, these
used to return a different value for temporary tables.
page_id_t: Add constexpr to most member functions.
mtr_t::log_write(): Catch log writes to invalid tablespaces
so that the test case would crash without the fix to
row_ins_sec_index_entry_low().
