Fix for Bug #1448 "Date parsing fails, and fails to complain 

about it". Now numbers representing illegal timestamps are 
converted to 0 value if they are stored as timestamp or 
datetime. This behaviour is consistent with manual and with 
behaviour of string -> timestamp conversion.


mysql-test/r/type_datetime.result:
  Added test if ranges are checked during 
  integer, string -> timestamp conversion
mysql-test/r/type_timestamp.result:
  Added test if ranges are checked during 
  integer, string -> datetime conversion
mysql-test/t/type_datetime.test:
  Added test if ranges are checked during 
  integer, string -> datetime conversion
mysql-test/t/type_timestamp.test:
  Added test if ranges are checked during 
  integer, string -> timestamp conversion
sql/field.cc:
  Checks of month, day, hour, minute and second ranges were added
  to storing of integer into Field_datetime and Field_timestamp
  and so for integer -> datetime, timestamp conversion.
