- MySQL Server does no longer hardcode error 1005 Can't create table
   when a CREATE TABLE fails.
 - Adapt to this behaviour by recording new .result file for affected
   testcases and accept error 1296 instead of 1005 in .test files.
  - A few "Unknown error" recorded which will be fixed separately
    if possible. Rumor says that "Can't create table, error: X" is just about as
    descriptive as "Unknown error X" anyway.
