DERBY2599_Use_collation_of_compilation_schema_and_not_current_schema_diff_v1.txt

Commited attached patch 
DERBY2599_Use_collation_of_compilation_schema_and_not_current_schema_diff_v1.txt
 using revision 543266. This commit makes sure that we use compilation schema 
rather than current schema to set the collation type of some of the character 
string type instances in Derby.

> Set correct collation type and derivation on DataTypeDescriptor(DTD).

> 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.
