Let the client retry longer, to make sure the server will time out before the
client gives up. Make it really longer to get a deterministic client exit
status (make sure it has time to reconnect after the server timeout).
This helps in the case where an intermediate certificate is directly trusted.
In that case we want to ignore what comes after it in the chain, not only for
performance but also to avoid false negatives (eg an old root being no longer
trusted while the newer intermediate is directly trusted).

As we're about to change the chain construction logic, we want to make sure
the callback will still be called exactly when it should, and not on the
(upcoming) ignored certs in the chain.
Tends to cause spurious failures on buildbots due to peer timing out.
Anyway, those tests are mainly for interop, any memory error is most likely
catched by some earlier self-op test. (Also, we'll run these tests with ASan
anyway.)
Once the mutex is acquired, we must goto cleanup rather that return.
Since cleanup adjusts the return value, adjust that in test cases.
Also, at cleanup we don't want to overwrite 'ret', or we'll loose track of
errors.

Apparently openssl s_server does not flush stdout, anyway sometimes the client
receives the reply and exits, thus terminating the test, before is request is
visible on the server's stdout. So, just don't check that, checking the
client's output and exit code is already enough.
Retry one time in case we have a client timeout. These should be fairly rare
but still happen from time to time with udp_proxy tests which is annoying, and
until now has never indicated an actual issue.
Rather than flat-out die when we can't see the server started with lsof, just
stop waiting and try to go ahead with the test. Maybe it'll work if there was
a problem with lsof, most probably it will fail, but at least we'll have the
log, and the results of the following tests.
Note: date +%s isn't POSIX, but it works at least on Linux, Darwin/FreeBSD and
OpenBSD, which should be good enough for a test script.
This is not required nor recommended by the protocol, and it's a layering
violation, but it's a know flaw in the protocol that you can't detect a PSK
auth error in any other way, so it is probably the right thing to do.
