Added code to adjust the field_length of user variables in dependence on the field type. Aded new constants for numeric field widths. include/mysql_com.h: BUG#4788 - show create table provides incorrect statement. Introduced definitions for default field width of numeric types. So common values can be used at different places in the code. mysql-test/r/variables.result: BUG#4788 - show create table provides incorrect statement. New test results. mysql-test/t/variables.test: BUG#4788 - show create table provides incorrect statement. Added a test for the bug. sql/item_func.cc: BUG#4788 - show create table provides incorrect statement. Added code to adjust the field_length of user variables in dependence on the field type. sql/sql_parse.cc: BUG#4788 - show create table provides incorrect statement. Changed numeric literals to the new constants.
