Tatsuhiro Tsujikawa 271f7fbbb6 Add nghttp2_on_invalid_header_callback
nghttp2_on_invalid_header_callback is similar to
nghttp2_on_header_callback, but the former is only called when the
invalid header field is received which is silently ignored when the
callback is not set.  With this callback, application inspects the
incoming invalid field, and it also can reset stream from this
callback by returning NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE, or using
nghttp2_submit_rst_stream() directly with the error code of choice.

We also added nghttp2_on_invalid_header_callback2, which uses
reference counted header fields.

Tatsuhiro Tsujikawa 3785cf07ba Add simple HTTP/2 extension framework
Application can utilize this framework to send/receive user defined
extension frames.  These frames are expected not to change existing
protocol behaviour.

Tatsuhiro Tsujikawa 9eff511c5e Add nghttp2_send_data_callback to send DATA payload without copying
To avoid buffer copy in nghttp2_data_source_read_callback, this commit
introduces NGHTTP2_DATA_FLAG_NO_COPY and nghttp2_send_data_callback.
By using NGHTTP2_DATA_FLAG_NO_COPY in
nghttp2_data_source_read_callback, application can avoid to copy
application data to given buffer.  Instead, application has to
implement nghttp2_send_data_callback to send complete DATA frame by
itself.  We see noticeable performance increase in nghttpd and
tiny-nghttpd using this new feature.  On the other hand, nghttpx does
not show such difference, probably because buffer copy is not
bottleneck.  Using nghttp2_send_data_callback adds complexity, so it
is recommended to measure the performance to see whether this extra
complexity worth it.

Tatsuhiro Tsujikawa a36c4c6f5f Add nghttp2_on_begin_frame_callback

received.

Tatsuhiro Tsujikawa 53ee21caa9 Remove nghttp2_on_unknown_frame_recv_callback
It is not used by library for a while.  It could be used to pass
unsupported extension frames to application, but its interface
requires library to buffer entire frame, which we'd like to avoid.
For unsupported extension frames, we will add new callbacks which does
not require buffering if they are required.

Tatsuhiro Tsujikawa ab5b81bee1 Hide nghttp2_session_callbacks details and provide setter like functions
To make it possible to add new callbacks without bumping so name, we
decided to hide details of nghttp2_session_callbacks.  We provide
setter like functions to set individual callback function.
