This fixes hex() so that it outputs the hex of the ASCII for the time
data to make it aligned with MariaDB. It also fixes the following
functions so that they use NOW() as a DATETIME with the input TIME added
to it:
* weekday()
* yearweek()
* monthname()
* last_day()
* year()
* weekofyear()
* week()
* to_days()
* quarter()
* month()
* dayofyear()
* dayofweek()
* dayofmonth()
* day()
* date()
For the initial BLOB/TEXT pull request we put them in the same bucket as
VARBINARY, forcing many functions to be disabled. This patch enables the
same TEXT function support as VARCHAR.
* TEXT and BLOB now have separate identifiers internally
* TEXT columns are identified as such in system catalog
* cpimport only requires hex input for BLOB, not TEXT
