Introduce a test that is supposed to verify the persistence of BPF resources based on underlying bpf_link usage. Test will: 1) create and bind two sockets on queue ids 0 and 1 2) run a traffic on queue ids 0 3) remove xsk sockets from queue 0 on both veth interfaces 4) run a traffic on queues ids 1 Running traffic successfully on qids 1 means that BPF resources were not removed on step 3). In order to make it work, change the command that creates veth pair to have the 4 queue pairs by default. Introduce the arrays of xsks and umems to ifobject struct but keep a pointers to single entities, so rest of the logic around Rx/Tx can be kept as-is. For umem handling, double the size of mmapped space and split that between the two sockets. Rename also bidi_pass to a variable 'second_step' of a boolean type as it's now used also for the test that is introduced here and it doesn't have anything in common with bi-directional testing. Drop opt_queue command line argument as it wasn't working before anyway.
