This adds some preparing patches for upcoming multiwrite modifications.
I will leave the dangerous patches for after 2.2 release.

In addition, I'd like a test for this (just the parameter would be enough). But
I don't object to this series without it.
Thanks for your comments. I will respin tomorrow.
What exactly would you like to check in a test?
Just give the parameter and test the query-block against it. I'd test the
default, switching it on, off and maybe even specify it for a non-root BDS to
see whether that works.
