Generate qualified data structures for *LOB sql data types

When generating data structures for BLOB & CLOB SQL data types, use a qualified data structure instead of using the variable name with _LEN and _DATA appended.

For example,

Currently, for this field definition,

DCL-S BLOBFIELD SQLTYPE(CLOB:16000000);   

the SQL preprocessor generates this

DCL-DS BLOBFIELD ;                                  

BLOBFIELD_LEN UNS(10);
BLOBFIELD_DATA CHAR(16000000) CCSID(*JOBRUNMIX);
END-DS PMRESPONSE;

Instead, generate this:

DCL-DS BLOBFIELD QUALIFIED ;                                  

LEN UNS(10);
DATA CHAR(16000000) CCSID(*JOBRUNMIX);
END-DS PMRESPONSE;

This would allow blob fields to be more idiomatically (i.e., BLOBFIELD.LEN and BLOBFIELD.DATA).

Additionally, blob fields could be passed as parameters to procedures.
