Previously, after seeing upgrade to HTTP/2, we feed data followed by
upgrade response headers directly to nghttp2_session_mem_recv() in
Curl_http2_switched(). But it turns out that passed buffer, mem, is
part of stream->mem, and callbacks called by
nghttp2_session_mem_recv() will write stream specific data into
stream->mem, overwriting input data. This will corrupt input, and
most likely frame length error is detected by nghttp2 library. The
fix is first copy the passed data to HTTP/2 connection buffer,
httpc->inbuf, and call nghttp2_session_mem_recv().
The CURLOPT_COOKIE doc says it "sets the cookie header explicitly in the
outgoing request(s)." However there seems to be some user confusion
about cookie modification. Document that the cookies set by this option
are not modified by the cookie engine.

This function makes a platform-specific absolute path which uses
backslashes on Windows. This form works when passing it on the
command-line, as well as if the source is on another drive.
Coverity CID 1299424 identified dead code because of checks that could
never equal true (if the mechanism's name was NULL).
Simplified the function by removing a level of pointers and removing the
loop and array that weren't used.
Replace use of assert with code that properly catches bad input at
run-time even in non-debug builds.
This flaw was sort of detected by Coverity CID 1299425 which claimed the
"case RTSPREQ_NONE" was dead code.
Coverity CID 1299426 warned about possible NULL dereference otherwise,
but that would only ever happen if we get invalid HTTP/2 data with
frames for stream 0. Avoid this risk by returning early when stream 0 is
used.
Prior to this change the description for SEC_E_ILLEGAL_MESSAGE was OS
and language specific, and invariably translated to something not very
helpful like: "The message received was unexpected or badly formatted."

With many easy handles using the same connection for multiplexing, it is
important we store and keep the transfer-oriented stuff in the
SessionHandle so that callbacks and callback data work fine even when
many easy handles share the same physical connection.
Previously, when we send all given buffer in data_source_callback, we
return NGHTTP2_ERR_DEFERRED, and nghttp2 library removes this stream
temporarily for writing. This itself is good. If this is the sole
stream in the session, nghttp2_session_want_write() returns zero,
which means that libcurl does not check writeability of the underlying
socket. This leads to very slow upload, because it seems curl only
upload 16k something per 1 second. To fix this, if we still have data
to send, call nghttp2_session_resume_data after nghttp2_session_send.
This makes nghttp2_session_want_write() returns nonzero (if connection
window still opens), and as a result, socket writeability is checked,
and upload speed becomes normal.
Stop curl from failing when non-fatal alert is received during
handshake. This e.g. fixes lots of problems when working with https
sites through proxies.
BoringSSL removed support for direct callers of SSL_CTX_callback_ctrl
and SSL_CTX_ctrl, so move to a way that should work on BoringSSL and
OpenSSL.

.. also make __func__ replacement in multi.
Prior to this change debug builds would fail to build if the compiler
was building pre-c99 and didn't support __func__.
We could get stream ID not in the hash in on_stream_close. For
example, if we decided to reject stream (e.g., PUSH_PROMISE), then we
don't create stream and store it in hash with its stream ID.
This commit requires nghttp2 v1.0.0 to compile, and migrate to v1.0.0,
and utilize recent version of nghttp2 to simplify the code,
First we use nghttp2_option_set_no_recv_client_magic function to
detect nghttp2 v1.0.0. That function only exists since v1.0.0.
Since nghttp2 v0.7.5, nghttp2 ensures header field ordering, and
validates received header field. If it found error, RST_STREAM with
PROTOCOL_ERROR is issued. Since we require v1.0.0, we can utilize
this feature to simplify libcurl code. This commit does this.
Migration from 0.7 series are done based on nghttp2 migration
document. For libcurl, we removed the code sending first 24 bytes
client magic. It is now done by nghttp2 library.
on_invalid_frame_recv callback signature changed, and is updated
accordingly.
