* remove unused mysql_option
* don't allocate 5GB of memory in the mtr tests
* restore the behavior in dynamic_column_offset_byte(), put the ifdef correctly
* prefer __attribute__((unused)) to #ifdef
* prefer UNINIT_VAR to LINT_INIT
* make most Warning_info users blissfully unaware of the postponed initialization
* use my_offsetof instead of offsetof where the compiler thinks the latter is incorrect
