Tatsuhiro Tsujikawa e219d6a94f nghttpx: Clarify error_reply upstream method
There is no application level failure in h1 upstream.  For h2, SPDY
upstreams, don't call DIE(), instead return -1 to delete handler.

Tatsuhiro Tsujikawa dce20c3e6a nghttpx: Check HTTP/2 downstream connection after certain idle time
Previously when requests are issued to HTTP/2 downstream connection,
but it turns out that connection is down, handlers of those requests
are deleted.  In some situations, we only know connection is down when
we write something to network, so we'd like to handle this kind of
situation in more robust manner.  In this change, certain seconds
passed after last network activity, we first issue PING frame to
downstream connection before issuing new HTTP request.  If writing
PING frame is failed, it means connection was lost.  In this case,
instead of deleting handler, pending requests are migrated to new
HTTP2/ downstream connection, so that it can continue without
affecting upstream connection.

Tatsuhiro Tsujikawa 9614611969 nghttpx: Limit # of downstream connections per host when h2 proxy is used
This commit limits the number of concurrent HTTP/1 downstream
connections to same host.  By defualt, it is limited to 8 connections.
--backend-connections-per-frontend option was replaced with
--backend-http1-connections-per-host, which changes the maximum number
of connections per host.  This limitation only kicks in when h2 proxy
is used (-s option).

This commit adds functionality to customize access logging format in
nghttpx.  The format variables are inspired by nginx.  The default
format is combined format.

Tatsuhiro Tsujikawa 154876a17b nghttpx: Apply TLS record length limit to DATA frame payload
This is not obvious but it makes intermediaries flush and forward DATA
frame boundary without excessive buffering.  Since we have different
TCP connections frontend and backend, this may not work.  This is
still experimental.

Tatsuhiro Tsujikawa f8c70993c0 nghttpx: Adjust TLS record size dynamically
Use the same behaviour the current Google server does: start with 1300
TLS record size and after transmitting 1MiB, change record size to
16384.  After 1 second idle time, reset to 1300.  Only applies to
HTTP/2 and SPDY upstream connections.

Tatsuhiro Tsujikawa b305495a75 nghttpx: Reset both timeouts when either read or write succeeds
Previously read and write timeouts work independently.  When we are
writing response to the client, read timeout still ticks (e.g., HTTP/2
or tunneled HTTPS connection).  So read timeout may occur during long
download.  This commit fixes this issue.  This commit only fixes the
upstream part.  We need similar fix for the downstream.

Tatsuhiro Tsujikawa 0209b7c083 nghttpx: Fix location rewrite is failed because request headers are empty
Previously we empties request headers after they are sent to
downstream in order to free memory.  But it turns out that we use
request headers when rewriting location header response field.  Also
user reported that request headers are useful to add new features.
This commits defers the deletion of request headers to the point when
response headers are deleted (which is after response headers are sent
to upstream client).

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 31528b6267 Use uint32_t for HTTP/2 error_code
h2-14 now allows extensions to define new error codes.  To allow
application callback to access such error codes, we uses uint32_t as
error_code type for structs and function parameters.  Previously we
treated unknown error code as INTERNAL_ERROR, but this change removes
this and unknown error code is passed to application callback as is.

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.

Tatsuhiro Tsujikawa d5dcbf6f3b nghttpx: Fix possible flow control issue
Previously we only update consumed flow control window when number of
bytes read in nghttp2 and spdylay callback is 0.  Now we notify
nghttp2 library the consumed bytes even if number of bytes read > 0.
This change also uses newly added spdylay_session_consume() API, so we
require spdylay >= 1.3.0.
