When our QSslSocketBackendPrivate (OpenSSL backend) was developed,
the ancient versions of OpenSSL did not have an API needed to pass
an application-specific data into verification callback. Thus the
developers resorted to the use of global variables (a list with errors)
and locks. Some of our auto-tests use QNAM and in-process server.
Whenever the client (essentially qhttpthreadeddelegate) and the server
live in different threads, any use of 'https' is dead-lock prone,
which recent events demonstrated and which were previously observed
but not understood properly (rare occasions, not always easy to
reproduce). Now we fix this for good by removing locking.
There are two places (in 5.12) where these locks are needed:
1. Before calling SSL_connect/SSL_accept (handshake) - here
we reuse the same trick we do in PSK callback ('SSL' has
an external data set, and it's 'this', meaning an object
of type QSslSocketBackendPrivate).
2. The static member function 'verify', here we do not have
'SSL', but we have our temporary 'X509_STORE', to which
we can directly attach an external data - a pointer to
a vector to collect verification errors.
Note, this change assumes that OpenSSL Qt is build/linked
against is at least of version 1.0.1 - we set external data
on SSL unconditionally (no version checks).

If this callback is not set then OpenSSL will call the callback
used for <= TLS 1.2 unconditionally when connecting. If using PSK it
will call it again later once the preshared key is needed.
We don't currently handle the TLSv1.3 PSK, but we definitely should.
But for now we can work around it - when psk_use_session_callback is
called we simply change the PSK callback to a dummy function whose only
purpose is to restore the old callback.
This is mostly done to keep behavior the same as it is now for users
(and to keep our tests running).
Later we can add a new signal and handle this new feature properly.

2. OpenSSL 1.1.1 first introduced TLS 1.3 support. OpenSSL 1.1 back-end is
compatible with OpenSSL 1.1.1, but would fail to extract/report protocol
versions and set versions like 'TLS 1.3 only' or 'TLS 1.3 or better' on a
new context. Given 1.1.1 is deployed/adapted fast by different distros,
and 5.12 is LTS, we fix this issue by introducing QSsl::Tls1_3 and
QSsl::Tls1_3OrLater.
SecureTransport, WinRT and OpenSSL below 1.1.1 will report an error in case
the application requests this protocol (SecureTransport in future will
probably enable TLS 1.3).
Saying all that, TLS 1.3 support is experimental in QSslSocket.

Some Linux distributions patch OpenSSL's soname, making builds
on such distributions not deployable elsewhere. The problem is that
the code loading OpenSSL symbols would attempt to use the soname
of the build machine, and therefore not finding the OpenSSL
libraries on the deploy system.
The binary builds of Qt for Linux are affected by this problem,
as they build under RHEL7.4 which changes to soname of OpenSSL to
a non-standard string. This makes the binary builds not pick up
OpenSSL 1.0 from the machine where the build gets installed on.
Given that in the pre-1.1 versions only the 1.0 series is supported,
bump the minimum requirement of Qt to that. The 1.0.x releases
(up to 1.0.2, at the time of this writing) have kept binary
compatibility, and advertise a soname of "1.0.0", which is used
by most distributions.
So, if loading of OpenSSL with the build-time soname fails,
try to load them with the "1.0.0" hardcoded soname.

This patch adds DTLS support to QtNetwork module (and its OpenSSL
back-end).
DTLS over UDP is defined by RFC 6347.
The new API consists of
1) QDtlsClientVerifier which checks if a client that sent us ClientHello
is a real DTLS client by generating a cookie, sending a HelloVerifyRequest
with this cookie attached, and then verifiying a cookie received back.
To be deployed in combination with a server-side QUdpSocket.
2) QDtls - initiates and proceeds with a TLS handshake (client or server
side), with certificates and/or pre-shared key (PSK), and encrypts/decrypts
datagrams after the handshake has finished.
This patch does not implement yet another UDP socket, instead
it allows use of existing QUdpSocket(s), by adding DTLS support
on top. OpenSSL back-end uses a custom BIO to make it work with
QUdpSocket and give a finer control over IO operations.
On the server side, demultiplexing is left to client code (could
be done either by connecting QUdpSocket or by extracting address/port
for an incoming datagram and then forwarding/dispatching them to
the corresponding QDtls object).

This patch-set implements a new QSslSocket backend based on OpenSSL 1.1.
1. General.
The code in this patch was organized to achieve these (somewhat contradicting)
objectives:
- keep the new code free of #if-ery, as far as possible;
- make it easy to clean away dead code when we're eventually able to retire
out-dated OpenSSL versions;
- reduce the amount of code duplication.
If changes in some file/component were insignificant (~5 one-liners per file),
we still use pp-checks like: #if QT_CONFIG(opensslv11) ... #else ... #endif -
the logic is simple and it's still easy to clean the code if we remove the legacy
back-end. Where it saved #if-ery, we also introduced 'forward-compatible'
macros implementing equivalents of 1.1 functions using older OpenSSL.
In case some class contains a lot of version-specific ifdefs (particularly where
nested #if-ery was complex) we choose to split code into: "pre11" h/cpp files,
"shared" h/cpp files (they preserve their original names, e.g qsslsocket_openssl.cpp)
and "11" h/cpp files. If in future we remove the legacy back-end, "pre11" should be
removed; "shared" and "11" parts - merged.
2. Configuration.
We introduced a new feature 'opensslv11' which complements the pre-existing
'openssl' and 'openssl-linked' features. The 'opensslv11' feature is enabled
by a simple test which either compiles successfully or ends in a compilation
error, depending on a value of the OPENSSL_VERSION_NUMBER constant. If the
feature was enabled, we also append an additional compilation flag
-DOPENSSL_API_COMPAT=0x10100000L to make sure our new code does not contain
deprecated structures, function calls, macro-invocations from OpenSSL < 1.1.
