      BUG#39802 On Windows, 32-bit time_t should be enforced
      
      A backport of fix for "BUG40092 - Storage engine API uses
      time_t datatype".
      
      Starting from MSVC C++ 2005 (v8), the default size of time_t
      is changed from 32-bit to 64-bit. As the result, the binaries
      built with pre-v8 MSVC C++ do not work with the binaries
      (storage engine plugins) built with v8 or after (server
      crashes).
      
      Fixed storage engine API to use datatype with known size
      (ulong) instead of time_t.
     @ sql/handler.h
        Bug#39802 On Windows, 32-bit time_t should be enforced
        
        Change create_time, check_time, update_time
        in the ha_statistics and PARTITION_INFO
        structures to ulong.
