[ovs-dev,v2,00/24] Add support for Linux kernels up to 5.8.x

This patch set will add support for Linux kernels up to 5.9. In
addition there are quite a few patches for openvswitch on the Linux
kernel mailing list that have not been backported - here is a first
batch attempting to catch up on some of that technical debt.  There
will be a follow up batch of patches to this one but I didn't want
the patch bomb to get too large.

---
V2 - V2 of this patch set changes the NEWS as suggested by Ilya
   - Moves the acinclude patch for 5.8 support to the end of the
     patch series
   - Reduces targeted Linux kernel support to 5.8 since 5.9 is
     still not baked
   - Updates the travis kernel test list
   - Adds tags from authors from the first patch series.

Ah, forgot something.  Passes Travis here:
