Fire CK constraints for LUA spaces.
To achieve this goal, we reworked data dictionary, to store ck
constraints in separate space _ck_constraints and updated data
migration script to migrate existent data there. This also would
be useful in future to implement ALTER SPACE ADD CONSTRAINT
operation. Now we do not support CK constraint creation on
non-empty space.
Each CK has own precompiled VDBE machine that performs this
check with tuple fields mapped to it's memory with sql_bind() api.
In case of ck constraint conflict detected by this VM we abort
the transaction and return error to user.
Finally, we introduced a LUA-wrapper that provide a user-friendly
way to manage space ck constraints.
Changes in version 5:
- a new tuple_fetcher class to access tuple fields fast
- refactored _ck_constraint space format and indexes
- one on_replace trigger for all ck constraints
- trim_space_snprintf fixes: do not trim substring in ' or "
- do not wrap ck_constraint methods
- many minor fixes
