Tatsuhiro Tsujikawa 303f0f3fcd nghttpx: Return 413 if request header is too large
For now, if request has request body, we'll issue RST_STREAM to inform
the peer to stop sending body.  RST_STREAM may be sent before error
page header or data, so peer may receive RST_STREAM only.

Tatsuhiro Tsujikawa 8c67bbe3a8 src: Avoid copy in evbuffer_pullup()
Previously, we use evbuffer_pullup(buf, -1) to linearize the memory
region and it may cause buffer copy.  To avoid this, we use the return
value of evbuffer_get_contiguous_space() as 2nd parameter.  According
to the libevent manual, by doing so evbuffer_pullup() will not copy or
modify any data in evbuffer.

Tatsuhiro Tsujikawa 22c88af1ab nghttpx: Resume deferred DATA after complete DATA frame arrived on backend
If SPDY or HTTP/2 ustream is used and HTTP/2 downstream is used, only
call {spdylay,nghttp2}_resume_data when complete DATA frame was read
in backend to avoid to transmit too small DATA frame to the upstream.

Tatsuhiro Tsujikawa e34b8ac7fb src: Avoid to call costly evbuffer_add() repeatedly
The profiler and benchmarking showed that calling evbuffer_add()

into one large chunk and call evbuffer_add() less times.

Tatsuhiro Tsujikawa 649586fff6 Add nghttp2_session_mem_send() API function
This function behaves like nghttp2_session_send(), but it does not
use nghttp2_send_callback to send data. Instead, it returns the
serialized data to trasmit and its length to the caller.

Tatsuhiro Tsujikawa e186e01933 Replace on_end_headers_callback with on_begin_headers_callback
Previously, there is inconsistency when on_frame_recv_callback
is called between HEADERS/PUSH_PROMISE and the other frames.
For former case, it is called before header block, in latter
case, it is called after whole frame is received. To make it
consistent, we call on_frame_recv_callback for HEADERS/PUSH_PROMISE
after its frame is fully received. Since on_frame_recv_callback
can signal the end of header block, we replaced on_end_headers_callback
with on_begin_headers_callback, which is called when the reception
of the header block is started.

Tatsuhiro Tsujikawa a3082b7c1e Remove nghttp2_on_data_recv_callback and nghttp2_on_data_send_callback
nghttp2_data is added to nghttp2_frame union. When DATA is
received, nghttp2_on_frame_recv_callback is called. When DATA is
sent, nghttp2_on_frame_send_callback is called.

Tatsuhiro Tsujikawa f59a9c5c58 nghttpx: Disable TLS renegotiation properly
4ed4efc does not disable TLS renegotiation at all, if client keeps
rengotiations without sending application data. In this change,
we intercept the raw incoming data from the client and if it is a
renegotiation, drop the connection immediately.

Tatsuhiro Tsujikawa 707a0b4103 Move name/value validation functions to src
nghttp2 library itself now accept octet header/value pairs,
completely not restricted by HTTP/1 header name/value rule.
The applications may impose restriction about them using
validators.

Tatsuhiro Tsujikawa 0e4b3d435e Emit header name/value pair using callback functions
Now, in nghttp2_on_frame_recv_callback, nva and nvlen in
HEADERS and PUSH_PROMISE frames are always NULL and 0 respectively.
The header name/value pairs are emitted successive
nghttp2_on_header_callback functions. The end of header fields are
signaled with nghttp2_on_end_headers_callback function.

Since NGHTTP2_ERR_PAUSE for nghttp2_on_frame_recv_callback is
introduced to handle header block, it is now deprecated.
Instead, nghttp2_on_header_callback can be paused using
NGHTTP2_ERR_PAUSE.

Tatsuhiro Tsujikawa ccfa13cd5b nghttpx: Rewrite location header field
We thought that this kind of rewrite can be achieved by the configuration
of the backend severs, but in some configuration, however, it may get
complicated. So we decided to implement at least location rewrite in
nghttpx.

This commit also contains a fix to the bug which prevents the http2
backend request from concatenating header fields with the same value.
