MDEV-23032 FLOOR()/CEIL() incorrectly calculate the precision of a DECIMAL(M,D) column
The code in Item_func_int_val::fix_length_and_dec_int_or_decimal() calculated badly the result data type for FLOOR()/CEIL(), so for example the decimal(38,10) input created a decimal(28,0) result. That was not correct, because one extra integer digit is needed. floor(-9.9) -> -10 ceil(9.9) -> 10 Rewritting the code in a more straightforward way. Additional changes: - FLOOR() now takes into account the presence of the UNSIGNED flag of the argument: FLOOR(unsigned decimal) does not need an extra digits. - FLOOR()/CEILING() now preserve the unsigned flag in the result data type is decimal. These changes give nicer data types.
