As the buffer was already pre-printed into, print it as a string
rather than a format-string.

Here the selftests lib parses header name, while expectes non-space word
ending with a column.

Currently, the test is racy and seems to not pass anymore.
In order to rectify it, aim on TCP_TW_RST.
Doesn't seem way too good with this sleep() part, but it seems as
a reasonable compromise for the test. There is a plan in-line comment on
how-to improve it, going to do it on the top, at this moment I want it
to run on netdev/patchwork selftests dashboard.
It also slightly changes tcp_ao-lib in order to get SO_ERROR propagated
to test_client_verify() return value.

Since commit f5769faeec36 ("net: Namespace-ify sysctl_optmem_max")
optmem_max is per-netns, so need of switching to root namespace.
It seems trivial to keep the old logic working, so going to keep it for
a while (at least, until kernel with netns-optmem_max will be release).
Currently, there is a test that checks that optmem_max limit applies to
TCP-AO keys and a little benchmark that measures linked-list TCP-AO keys
scaling, those are fixed by this.

In unsigned-md5 selftests ip_route_add() is not needed in
client_add_ip(): the route was pre-setup in __test_init() => link_init()
for subnet, rather than a specific ip-address.
Currently, __ip_route_add() mistakenly always sets VRF table
to RT_TABLE_MAIN - this seems to have sneaked in during unsigned-md5
tests debugging. That also explains, why ip_route_add_vrf() ignored
EEXIST, returned by fib6.
Yet, keep EEXIST ignoring in bench-lookups selftests as it's expected
that those selftests may add the same (duplicate) routes.

There are a handful of spelling mistakes in test messages in the
TCP-AIO selftests. Fix these.

Check that both active and passive reset works and correctly sign
segments with TCP-AO or don't send RSTs if not possible to sign.
A listening socket with backlog = 0 gets one connection in accept
queue, another in syn queue. Once the server/listener socket is
forcibly closed, client sockets aren't connected to anything.
In regular situation they would receive RST on any segment, but
with TCP-AO as there's no listener, no AO-key and unknown ISNs,
no RST should be sent.
And "passive" reset, where RST is sent on reply for some segment
(tcp_v{4,6}_send_reset()) - there use TCP_REPAIR to corrupt SEQ numbers,
which later results in TCP-AO signed RST, which will be verified and
client socket will get EPIPE.
No TCPAORequired/TCPAOBad segments are expected during these tests.

Provide functions to create selftests dedicated to TCP-AO.
They can run in parallel, as they use temporary net namespaces.
They can be very specific to the feature being tested.
This will allow to create a lot of TCP-AO tests, without complicating
one binary with many --options and to create scenarios, that are
hard to put in bash script that uses one binary.
