* allow varchar() to only store used bytes, not maximum

Hmm. Some file managers might make use of the fact that a column is of
fixed storage size, which I would think varchar() should be. Also, it
would possibly allow rows to be updated in place with predictable
performance. The text type (or varchar w/o maximum specified) are
available for truely variable length fields. I'll bet that others DBs
make these assumptions too...

Char() is now fixed, varchar() is not, hence the varchar name. text is
unchanged.
