* automatically disable ps2 and cursor protocol when the
select statement returns no result set
* remove manual {disable|enable}_{ps2|cursor}_protocol from around
`select ... into` in tests
* other misc collateral test cleanups
Updated tests: cases with bugs or which cannot be run
with the cursor-protocol were excluded with
"--disable_cursor_protocol"/"--enable_cursor_protocol"
Fix for v.10.5
for general use.
