Replace WARN_ONCE() that can be triggered from userspace with
pr_warn_once(). Those still give user a hint what's the issue.
I've left WARN()s that are not possible to trigger with current
code-base and that would mean that the code has issues:
- relying on current compat_msg_min[type] <= xfrm_msg
Add error handling in case of failure to send switching data path message
to the host.

The usage of the condition variable is broken, and overkill. Replace it
with a pthread barrier.

There is really no reason to have a non-default thread stack
size. Remove that.

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
Libbpf's xsk part calls get_channels() API to retrieve the queue count
of the underlying driver so that XSKMAP is sized accordingly.
Implement that in veth so multi queue scenarios can work properly.

Tx thread needs to be started after the Rx side is fully initialized so
that packets are not xmitted until xsk Rx socket is ready to be used.
It can be observed that atomic variable spinning_tx is not checked from
Rx side in any way, so thread_common_ops can be modified to only address
the spinnin
Currently, there is a testapp_sockets() that acts like a wrapper around
testapp_validate() and it is called for bidi and teardown test types.
Other test types call testapp_validate() directly.
Split testapp_sockets() onto two separate functions so a bunch of bidi
specific logic can be moved there
Let's a have a separate Tx/Rx worker threads instead of a one common
thread packed with Tx/Rx specific checks.
Move mmap for umem buffer space and a switch_namespace() call to
thread_common_ops.
This also allows for a bunch of simplifactions that are the subject of
the next commits. The final res
