I pushed changeset:   8803:f14892f7ed88

to revert some changes as my changes to fix this issue broke CI.

This commit restored check_inner() to the backend files and removed it
from hyperdb. It also undid the changes to set_inner().

It looks like there is some internal state or database changes that
happened
with my original commit. These resulted in import/export failing,
Multilink filtering
and other failures.

I think there is a dependency on order of operations and moving checks
around
broke something. I use testmon which filters out tests that do not run
through changed
code to reduce the time for test runs on my pc. However internal state
changes and
database changes that affect code in other code paths aren't detectable
by testmon's algorithm.
