Tatsuhiro Tsujikawa 8bac5899cc nghttpx: Handle h2 backend error per Downstream
Previously we wrongly handles stream per connection when h2 backend
failed or closed.  If upstream is h2 or spdy, streams which are not
associated to the failed h2 backend are also handled, which is
unnecessary.

Tatsuhiro Tsujikawa f5a2f1da25 nghttpx: Add --frontend-http2-window-size option, and its family
We added --frontend-http2-window-size,
--frontend-http2-connection-window-size, --backend-http2-window-size,
and --backend-http2-connection-window-size option to replace existing
*-bits options.  The old options are not flexible because they only
specify number of bits.  Now we can specify integer value, with
possible g, m, and k unit.  The old options are still available for
backend compatibility, but are deprecated.

Tatsuhiro Tsujikawa 1753bea692 nghttpx: Support server push from HTTP/2 backend
This commits enables HTTP/2 server push from HTTP/2 backend to be
relayed to HTTP/2 frontend.  To use this feature, --http2-bridge or
--client is required.  Server push via Link header field contiues to
work.

Tatsuhiro Tsujikawa 446de923f3 nghttpx: Support multiple HTTP/2 session per worker
Currently, we use same number of HTTP/2 sessions per worker with given
backend addresses.  New option to specify the number of HTTP/2 session
per worker will follow.

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).

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 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.

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()
repeatedly is very costly. To avoid this, we buffer up small writes
into one large chunk and call evbuffer_add() less times.

Tatsuhiro Tsujikawa 9ba19df813 shrpx: Add --spdy-bridge option
With --spdy-bridge option, it listens SPDY/HTTPS connections from
front end and forwards them to the backend in SPDY. The usage will be
written later. This change fixes the crash when more than 2
outstanding SpdyDownstreamConnection objects are added to SpdySession
and establishing connection to SPDY backend is failed.

Tatsuhiro Tsujikawa fa552c6788 shrpx: Share SPDY session among multiple frontend connections per thread
In client mode, now SPDY connection to the backend server is
established per thread.  The frontend connections which belong to the
same thread share the SPDY connection.

Tatsuhiro Tsujikawa 026f4ca3a2 Add --client-mode option
With --client-mode option, shrpx now accepts unencrypted HTTP
connections and communicates with backend server in SPDY.  In short,
this is the "reversed" operation mode against normal mode.  This may
be useful for testing purpose because it can sit between HTTP client
and shrpx "normal" mode.

Tatsuhiro Tsujikawa b0fcd68783 Move spdycat, spdyd and shrpx from examples to src
To distinguish the to-be-installed programs and non-installable

were moved to src directory. spdynative was removed from Makefile
because it does not appeal to any users much.
