This is not very useful for TLS as mbedtls_ssl_write() will automatically
fragment and return the length used, and the application should check for that
anyway, but this is useful for DTLS where mbedtls_ssl_write() returns an
error, and the application needs to be able to query the maximum length
instead of just guessing.
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.)
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.
closes#227
openssl s_server up to 1.0.2.a included uses a 512-bit prime for DH by
default. Since we now require 1024 bit at least, make s_server use decent
params. (1.0.2b and up use acceptable params by default.)

With exchanges == renego period, sometimes the connection will be closed by
the client before the server had time to read the ClientHello, making the test
fail. The extra exchange avoids that.
