Check the NPN result before preparing an HTTP request and switch into
HTTP/2.0 mode if necessary. This is a work in progress, the actual code
to prepare and send the request using nghttp2 is still missing from
Curl_http2_send_request().
the number of elements in the 'nghttp2_session_callbacks' structure is
now reduced by 2 in version 0.3.0 (I'm not sure when the change
happened, but checking for ver 0.3.0 work for me).
Something is wrong in 'userp' for the HTTP2 recv_callback(). The
session is created using bogus user-data; '&conn' and not 'conn'.
I noticed this since the socket-value in Curl_read_plain() was set to a
impossible high value.
Using the first little merge of nghttp2 into libcurl, I stumbeled on the
missing 'snprintf' in MSVCRT. Isn't this how we do it for other libcurl
files? I.e. use 'curl_msnprintf' and not 'snprintf' directly:
