Clean code a bit and fix a couple of small bugs in ext-refs

Browse Source 
Currently the patch does not have any impact on the RD performance. The
fix could however potentially help on the next step of work, especially
when the extra altref frames allow non-zero temporal filtering strength
and their corresponding OVERLAY frames, i.e. the INTNL_OVERLAY frames
are being added.
