In main.index_merge_myisam we remove the test that was added in
commit a2d24def8c because
it duplicates the test case that was added in
commit 5af12e4635.
Preparation for MDEV-16210:
replace.test:
key_type combinations: PK and UNIQUE.
foreign.test:
Preparation for key_type combinations.
Other fixes:
* Merged versioning.update2 into versioning.update;
* Removed test2 database and done individual drop instead.
* do not allow versioned table to be without versioned (non-system) fields
* prohibit changing field versioning, when removing table versioning
* handle CREATE...SELECT as well
For MODE_SIMULTANEOUS_ASSIGNMENT it is required to return back field
offsets from record[1] to record[0]. 'continue' in warning branch did
skip of rfield->move_field_offset() call.
* Fine-grained inplace skipping by INNOBASE_ALTER_VERSIONED_REBUILD;
* Fixed column WITHOUT SYSTEM VERSIONING + ADD COLUMN;
* Fixed instant field change (MDEV-16330);
* Revisited test versioning.online;
* Merged the test versioning.trx_id_versioning_attribute_persistence
to versioning.online;
* Renamed some versioning functions:
** change_fields_versioning_cache() -> vers_change_fields_cache()
** change_field_versioning_try() -> vers_change_field_try()
Skip condition moved out of func.

TODO:
MDEV-16301 IB: use real table name for error messages on ALTER
Closes tempesta-tech/mariadb#491
Closes#748
MDEV-14823 Wrong error message upon selecting from a system_time partition
MDEV-15956 Strange ER_UNSUPPORTED_ACTION_ON_GENERATED_COLUMN upon ALTER on versioning column
Introduced new alter algorithm type called NOCOPY & INSTANT for
inplace alter operation.
NOCOPY - Algorithm refuses any alter operation that would
rebuild the clustered index. It is a subset of INPLACE algorithm.
INSTANT - Algorithm allow any alter operation that would
modify only meta data. It is a subset of NOCOPY algorithm.
Introduce new variable called alter_algorithm. The values are
DEFAULT(0), COPY(1), INPLACE(2), NOCOPY(3), INSTANT(4)
Message to deprecate old_alter_table variable and make it alias
for alter_algorithm variable.
alter_algorithm variable for slave is always set to default.
