DBMS_OUTPUT: Missing 32767 byte max line size enforcement

[rophy]

Description

IvorySQL's DBMS_OUTPUT implementation does not enforce Oracle's 32767 byte maximum line size limit.

Oracle Behavior

Per Oracle documentation:

The maximum line size is 32767 bytes.

When exceeded, Oracle raises:

ORA-20000: ORU-10028: line length overflow, limit of 32767 bytes

IvorySQL Behavior

IvorySQL accepts lines of any length (tested with 50000 bytes successfully).

Test Case

-- This should fail with ORU-10028 but succeeds in IvorySQL
DO $$
DECLARE
    chunk TEXT := repeat('A', 25000);
BEGIN
    dbms_output.enable(100000);
    dbms_output.put(chunk);
    dbms_output.put(chunk);  -- 50000 bytes total
    dbms_output.new_line();
END;
$$;

Expected Fix

Add line length check in pl_dbms_output.c for both PUT and PUT_LINE functions. When line exceeds 32767 bytes, raise error:

ORU-10028: line length overflow, limit of 32767 bytes
