Tatsuhiro Tsujikawa 0e8419ac37 nghttpx: Add backend-connections-per-frontend option
This option limits the number of backend connections per frontend.
This is meaningful for the combination of HTTP/2 and SPDY frontend and
HTTP/1 backend.

Tatsuhiro Tsujikawa 24cfb52b5a nghttpx: Add --no-location-rewrite option
--no-location-rewrite option disallows location header rewrite on
--http2-bridge, --client and default mode.  This option is useful when
connecting nghttpx proxy with --http2-bridge to backend nghttpx with
http2-proxy mode.

Tatsuhiro Tsujikawa 0ce848a611 nghttpx: Rewrite logging system
This change rewrites logging system of nghttpx.  Previously access log
and error log are written to stderr or syslog and there was no option
to change stderr to something else.  With this change, file path of
access log and error log can be configured separately and logging to
regular file is now added.  To support rotating log, if SIGUSR1 signal
is received by nghttpx, it closes the current log files and reopen it
with the same name.  The format of access log is changed and has same
look of apache's.  But not all columns are not supported yet.

Simplified when to send WINDOW_UPDATE to the backend, that is we send
WINDOW_UPDATE when input buffer is empty.

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

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.

Tatsuhiro Tsujikawa 01f7162be3 nghttpx: Add connection-level flow control window size options
This commit also changes SPDY's flow control size. Previously,
the size for SPDY is the same amount of bytes with HTTP/2.
For example, --frontend-http2-upstream-window-bits=N,
the window size is 2**N - 1. Now SPDY code uses 2**N.
