MDEV-5271 Support engine-defined attributes per partitionbb-10.8-mdev-5271
Make it possible to specify engine-defined attributes on partitions
as well as tables.
If an engine-defined attribute is only specified at the table level,
it applies to all the partitions in the table.
This is a backward-compatible behavior.
If the same attribute is specified both at the table level and the
partition level, the per-partition one takes precedence.
So, we can consider per-table attributes as default values.
One cannot specify engine-defined attributes on subpartitions.
Implementation details:
* We store per-partition attributes in the partition_element class
because we already have the part_comment field, which is for
per-partition comments.
* In the case of ALTER TABLE statements, the partition_elements in
table->part_info is set up by mysql_unpack_partition().
So, we parse per-partition attributes after the call of the function.
