don't attempt mismatch logic if there's no columns to look for. fall through to sql server and do a lookup on the first column.

Blob stream

pull 6.4.0

removed arraylist to avoid costly traversal. Blobs now fill anytime the resultset moves its cursor.

added tests which specifically test blob streams and behavior after the RS is closed.

This reverts commit bc074f2, reversing
changes made to 19e8339.

No longer fills blobs on every checkClosed() call. Only attempts to fill them in scenarios where the cursor moves or another change of state which causes the RS to lose its active stream.

wasNull() moves the cursor for some reason, need to fill blobs.

Update SNAPSHOT for upcoming preview release.
