of ER_WRONG_OBJECT
ER_CHECK_NO_SUCH_TABLE was raised because a view does not have
the corresponding TABLE instance connected to TABLE_LIST and the
server interprets the absence as the absence of the table itself.
To fix the problem, we add a check to ensure that the target table
to be swapped with a partition is not a view.

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.

Dead code cleanup:
part_info->num_parts usage was wrong and working incorrectly in
mysql_drop_partitions() because num_parts is already updated in
prep_alter_part_table(). We don't have to update part_info->partitions
because part_info is destroyed at alter_partition_lock_handling().
Cleanups:
- DBUG_EVALUATE_IF() macro replaced by shorter form DBUG_IF();
- Typo in ER_KEY_COLUMN_DOES_NOT_EXITS.
Refactorings:
- Splitted write_log_replace_delete_frm() into write_log_delete_frm()
and write_log_replace_frm();
- partition_info via DDL_LOG_STATE;
- set_part_info_exec_log_entry() removed.
DBUG_EVALUATE removed
DBUG_EVALUTATE was only added for consistency together with
DBUG_EVALUATE_IF. It is not used anywhere in the code.
DBUG_SUICIDE() fix on release build
On release DBUG_SUICIDE() was statement. It was wrong as
DBUG_SUICIDE() is used in expression context.

RocksDB is substituted silently
- There should be no substitution if engine exists, only when doesn't
exist
- Handling of an error when sys_var `default_tmp_storage_engine` is
assigned to unsupported engine.
- rocksdb doesn't support embedded server ebfc4e6ad02 so is excluded
Closes PR #774

bitmap_is_set(table->read_set, field_index))' fails upon attempt to update virtual column on partitioned versioned table
When using buffered sort in `UPDATE`, keyread is used. In this case,
`TABLE::update_virtual_field` should be aborted, but it actually isn't,
because it is called not with a top-level handler, but with the one that
is actually going to access the disk. Here the problemm is issued with
partitioning, so the solution is to recursively mark for keyread all the
underlying partition handlers.
* ha_partition: update keyread state for child partitions
Closes #800
