                DERBY2599_set_correct_collation_for_params_and_string_functions_v1_diff.txt

Committed patch DERBY2599_set_correct_collation_for_params_and_string_functions_v1_diff.txt
with following commit comments
"DERBY-2599
Commiting the patch which makes sure that JDBC parameters take their ollation type from the
schema in which they are getting compiled. This involved quite a few classes. I have added
quite a few test cases. Test cases are required for LIKE, user defined functions, IS NULL.
The commit also implements the fact that the result character string types from UPPER, LOWER,
TRIM(LTRIM, RTRIM), SUBSTR will have the same collation as their operand."

> DTD has TypeDescriptorImpl in it which has 2 new fields, namely, collationType and collationDerivation.
These 2 fields are available for all different types of DTDs but only apply to character types.
The other datatypes should ignore these 2 fields.
> This Jira is a placeholder for loading the correct values into collationType and collationDerivation.
