Follow up 217e7006. Avoid the very expensive iteration to
find matching features when a subset string is set by
instead querying the original, unfiltered layer when
we are doing a FilterFids type request.
Fixes many hangs when using OGR layers with filters in place.
When inserting features whose attribute column corresponding to the pkid
is empty, and tat this pkid column has a default value using a sequence,
then we can remove it from the INSERT statement completely, which save us
from doing a SELECT nextval(...) for each row. On the provided test case
of that ticket, on a debug build, this cuts down the insertion time from 5 minutes
to 1 minute 10s.
For some reason QPicture.detach() doesn't seem to always work as intended, at
least with QT 5.5 on Ubuntu 16.04
Serialization/deserialization is a safe way to be ensured we don't
share a copy.

otherwise if you access the config of the filter (or change app settings) from outside the main application settings dialog, results are not invalidate
for instance, if you update a URL of a service, results won't be updated

We don't want to expose this field to users, or include it in layer
exports or copies
And rename internal field to __orig_ogc_fid to avoid clashes with
existing datasets which have been exported before this fix and which
now contain a orig_ogc_fid field
