Timestamp-based versioning for InnoDB [ closes #209 ]
...
* Removed integer_fields check
* Reworked Vers_parse_info::check_sys_fields()
* Misc renames
* versioned as vers_sys_type_t
* Removed versioned_by_sql(), versioned_by_engine()
versioned() works as before;
versioned(VERS_TIMESTAMP) is versioned_by_sql();
versioned(VERS_TRX_ID) is versioned_by_engine().
* create_tmp_table() fix
* Foreign constraints for timestamp-based
* Range auto-specifier fix
* SQL: 1-row partition rotation fix [fixes #260 ]
* Fix 'drop system versioning, algorithm=inplace'

for now, remove FOR SYSTEM_TIME at the end of the query
...
non-standard, redundant, potentially risky in the future,
hides bugs. See #383 , #384 , #385

SELECT * FROM (t1 join t2) FOR SYSTEM_TIME ...
was not an error.

SQL: regression fix: make NOW a valid identifier again [ #363 ]
...
* again, as in 10.2, NOW is a keyword only if followed by parentheses
* use AS OF CURRENT_TIMESTAMP or AS OF NOW()
* AS OF CURRENT_TIMESTAMP and AS OF NOW() mean AS OF NOW(6),
not AS OF NOW(0), (same behavior as in a DEFAULT clause)
