59a00868c9 row0mysql.c: 
Play safe and set a MySQL 1 - 12 byte BLOB reference to zero except for the length and pointer areas in it

5aa9a391f5 row0mysql.c: 
Add some diagnostic code to track BLOB bugs if they were not already fixed with the change in row0sel.c
row0sel.c:
  Fix a seg fault which was caused inside MySQL because InnoDB when returning a BLOB value did not initialize the length and the data pointer of a BLOB whose value is the SQL NULL; also fix a very improbable race condition which could occur if a row with an externally stored BLOB was fetched using the adaptive hash index

522ee5a0cf srv0srv.c: 
If the default character set was set to non-latin1 then the collation order of DATA_CHAR and DATA_VARCHAR was not defined, and foreign key system tables did not work, because they contain DATA_VARCHAR columns
