Previously we were always setting SpdyWasUsedAttribute for SPDY/HTTP/2/HTTP/1.1
(true/false) which is confusing. Now if HTTP2AllowedAttribute was set to true on
a request, we set HTTP2WasUsedAttribute. Otherwise, as we did before, we're setting
SpdyWasUsedAttribute.

After it started to fail (somehow it's only OpenSUSE 42.1) again and again
and after a quick re-evaluation it appears the logic testing SETTINGS|ACK
is incorrect. We (client side) start by sending the preface and then
continue to send our request(s). The other side (server) starts from sending its
SETTINGS frame. These settings must be ACKed, but apparently it can happen,
that server receives a requests and sends a reply before it receives SETTINGS|ACK,
resulting in replyFinished (replyFinishedWithError) signal and event loop stopping.
As a result - QVERIFY(serverGotSettingsACK) fails.

- Fix the case when we erroneously handled stream ID == 0 in a GOAWAY frame as
an invalid stream ID.
- _q_receivedReply: convert do{}while() loop into to while(){} to prevent
it from handling any frames after GOAWAY frame received and all active frame
finished.
- sendRequest - if we received GOAWAY, also clear spdyRequests in the connection
channel, otherwise it keeps re-trying to send requests!
- Http network connection channel never resets a protocolHandler in _q_encrypted/
_q_connected, which is BAD for HTTP/2, since HTTP/2 has unique per-connection
compression context and must be reset - now we recreate the protocol handler in
_q_encrypted or _q_connected (https/http).
- Update autotest.

HTTP/2 allows a server to pre-emptively send (or "push") responses (along
with corresponding "promised" requests) to a client in association with a
previous client-initiated request. This can be useful when the server
knows the client will need to have those responses available in order
to fully process the response to the original request.
Server push is semantically equivalent to a server responding to a request;
however, in this case, that request is also sent by the server, as a
PUSH_PROMISE frame.
The PUSH_PROMISE frame includes a header block that contains a complete set
of request header fields that the server attributes to the request.
After sending the PUSH_PROMISE frame, the server can begin delivering the
pushed response as a response on a server-initiated stream that uses the
promised stream identifier.
This patch:
- fixes the HPACK decompression of PUSH_PROMISE frames;
- allows a user to enable PUSH_PROMISE;
- processes and caches pushed data for promised streams;
- updates auto-test - emulates a simple PUSH_PROMISE
scenario.

Introduce new entity: class Http2::Frame with accessors like
payloadSize/type/flags/streamID etc. (they actually read
/interpret raw bytes from a frame's buffer) instead of
duplicating this functionality in reader/writer classes.
Delete defaulted members and remove explicitly defined
move ctors/operators (not needed actually).
Update auto-test ('HTTP/2 server') to use these new classes.

Since headersFrame is a reference to a vector's element, clearing this
vector before accessing headersFrame.flags is not a good idea, must be
done later.

HTTP/2 does not require TLS connection, it can work in a cleartext mode.
Plus at the moment only OpenSSL backend allows HTTP/2 negotiation
via ALPN/NPN (and none of our CI configurations with OpenSSL supports
these extensions, rendering HTTP/2 auto-test useless). This patch
implements cleartext HTTP/2 ('h2c') in 'direct' mode - this is
allowed if a client has a prior knowledge that HTTP/2 is supported by
a server.
