the UDF
When deleting a user defined function MySQL must remove it from both the
in-memory hash table and the mysql.proc system table.
Finding (and removal therefore) from the internal hash table is case 
insensitive (or whatever the default charset is), whereas finding and 
removal from the system table is case sensitive.
As a result if you supply a function name that is not in the same character
case to DROP FUNCTION the server will remove the function only from the
in-memory hash table and will keep the row in mysql.proc system table.
This will cause inconsistency between the two structures (that is fixed
only by restarting the server).
Fixed by using the name in the precise case (from the in-memory hash table)
to delete the row in the mysql.proc system table. 

Removed an assertion that was not valid for the cases where the query
in a prepared statement contained a single-row non-correlated
subquery that was used as an argument of the IS NULL predicate.

and no WHERE condition were applied for any subquery without tables.

datafile added to be used in gis.test

The problem is that the GEOMETRY NOT NULL can't automatically set
any value as a default one. We always tried to complete LOAD DATA
command even if there's not enough data in file. That doesn't work
for GEOMETRY NOT NULL. Now Field_*::reset() returns an error sign
and it's checked in mysql_load()
