Bug#21620 ALTER TABLE affects other columns
Problem: for character sets having mbmaxlen==2,
any ALTER TABLE changed TEXT column type to MEDIUMTEXT,
due to wrong "internal length to create length" formula.
Fix: removing rounding code introduced in early 4.1 time,
which is not correct anymore.

Fixing "internal length to create length" formula.
