Merge 10.1 to 10.2.

Most notably, this includes MDEV-11623, which includes a fix and
an upgrade procedure for the InnoDB file format incompatibility
that is present in MariaDB Server 10.1.0 through 10.1.20.

In other words, this merge should address
MDEV-11202 InnoDB 10.1 -> 10.2 migration does not work
