Bug #27545888 MYSQLD CRASHES WHEN RENAMING AN INNODB TABLE WITH FOREIGN

KEY AND FULLTEXT KEY

PROBLEM

When renaming a table, foreign key constraint name is duplicated and is
not handled therefore crashes later during query execution.

FIX

Handle the particulary duplicate key error case by exiting function and
return error to server.

NOTE: For 8.0+, Added to this issue fixed another issue that we are writing
rename log in case of rollback also so made the call to
row_rename_table_for_mysql based on the replay hint coming from
fts_rename_aux_tables.
Also added crash injection test incase of rename table crash/recovery
rollback.
