cpimport would truncate UTF8 data half way through a character which
would cause problems for functions using that data. This patch
calculates the correct truncation point when inserting the data.
DOUBLE typecast was not supported and the failure detection caused a
crash.
This patch adds support for DOUBLE typecast and fixes the crash caused
when a non-supported function is detected as part of an arithmatic.

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
Functions such as reverse() that do float/double to string conversion
use printf's %g to do it. Unfortunately this adds a '+' symbol before
the exponent symbol. MariaDB doesn't do this.
This patch builds the string in a way that does not have that problem,
it resembles the way it is done elsewhere in the codebase.
In MariaDB (unlike MySQL) max/min time values include msec of 999999.
This means that subtime() with saturated values can be off by one
second.
For this calculation I have modified add_time (which also does
subtime()) to have a saturated value including 999999 msec. This fixes
the subtime test in the regression suite.
Datetime has internal int value which is very different to MySQL's int
value. This patch differentiates between the two and also fixes a column
width issue which appeared once the datetime handling was fixed.
* The year() function did not handle float/double input correctly
* Makedate() did not handle year < 100 conversion
* 0 date was converted to NULL for some functions
In addition makedate did
