8f58e1319c tst_qdtls: add 'invalidConfiguration' test
Test that we don't silently replace an invalid TLS configuration with
the default one (for now, the only thing that is considered to be
non-valid - is having non-DTLS protocol set).

ab731692e2 QDtls: delay protocol version verification
A weird behavior of the DTLS server example, when linked with 1.0.2,
exposed that client code, requesting an invalid protocol (for example, SSLv3)
can end-up with connection encrypted with DTLS 1.2 (which is not that bad,
but totally surprising). When we check the protocol version early in
setDtlsConfiguration() and find a wrong version, we leave our previous
configuration intact and we will use it later during the handshake.
This is wrong. So now we let our user set whatever wrong configuration they
have and later fail in TLS initialization, saying -
'Unsupported protocol, DTLS was expected'.

Auto-test was reduced - the follow-up patch will introduce a new
'invalidConfiguration' auto-test.

9f2a671560 Extend 'ignoreExpectedErrors' test
with a case when we fail to ignore/pre-set one of possible
verification errors.

5c7d2033e0 QDtls: respect pre-set verification errors
That's actually how ignoreVerificationErrors (and QSslSocket::ignoreSslErrors)
are used to set the expected/known verification errors before handshake.
Auto-test updated too.

8948491eda QDtls - use conventional names
More Qt-style and more natural, also, shorter names.

056fbf03a5 QDtls - refactor
This patch renames rather awkward 'remote' into more conventional
'peer' (similar to what we have in QAbstractSocket).

5bd9f98342 QDtls - handle server-side timeouts
According to RFC 6347 a DTLS server also must retransmit buffered message(s)
if timeouts happen during the handshake phase (so it's not a client only as
I initially understood it).

Conveniently so an auto-test is already in place and needs just a tiny
adjustment - handshakeWithRetransmission covers both sides.

5417949fe2 Add tst_QDtls auto-test
The test is somewhat similar to tst_QSslSocket but is smaller (in scope, will
grow in future), it has no QTcpSocket/QAbstractSocket-specific things and
has more DTLS-specific code. At the moment it does not use our network
test server, all work is done in the same process with two QUdpSockets
and two QDtls objects. We test (both on client/server ends):
 - parameters validation (for all functions that do this) and
   the correctness of error codes/handshake states
 - handshake procedure (with/out certificates and with pre-shared keys)
 - timeouts and re-transmissions during (D)TLS handshake
 - peer verification (and related verification errors)
 - aborted/resumed handshake
 - encrypted I/O
 - DTLS shutdown

For now, this test is OpenSSL-only.
