nghttpx: Add --accesslog-write-early option
...
--accesslog-write-early option is analogous to HAProxy's logasap. If
used, nghttpx writes access log when response header fields are
received from backend rather than when request transaction finishes.

nghttpx: Don't write again after failure
...
Plain write(2) is OK, but SSL_write requires same arguments on retry.
It would be better to avoid calling them again.

nghttpx: Keep reading after backend write failed
...
Because of bidirectional nature of TCP, we may fail write(2), but have
still pending read in TCP buffer, which may contain response body. To
forward them, we should keep reading until get EOF from backend.
To avoid stalling HTTP/1 upload when request buffer is full, and we
have received complete response from backend, drop connection in that
case.

We have added "dns" parameter to backend option. If specified, name
lookup is done dynamically. If not, name lookup is done at start up,
or configuration reloading. nghttpx caches DNS result including error
case in 30 seconds in this commit. Later commit makes this
configurable.
DNS resolution is done asynchronously using c-ares library.

It is very hard to support multiple protocols in backend while

emulated using combinations of options. Now the backend connection is
not encrypted by default. To enable encryption on backend connection,
use --backend-tls option.

nghttpx: Rewrite backend HTTP/2 connection coalesce strategy
...
Previously, we use one Http2Session object per DownstreamAddrGroup.
This is not flexible, and we have to provision how many HTTP/2
connection is required in advance. The new strategy is we add
Http2Session object on demand. We measure the number of attached
downstream connection object and server advertised concurrency limit.
As long as former is smaller than the latter, we attach new downstream
connection to it. Once the limit is reached, we create new
Http2Session object. If the number lowers the limit, we start to
share Http2Session object again.

We modeled max_header_fields and header_field_buffer limit from Apache

header fields, while we applied both request and response. Since
nghttpx is used as reverse proxy and backend server is relatively
"trusted", this commit removes the application to response header
fields.

...
It seems that using ev_feed_event to signal write operation is much
faster than starting watcher. This is probably due to the fact that
we don't need to wait in event loop. The same thing cannot be done in
HTTP/2 frontend, since this will raise write operation for each stream
HEADER/DATA write, which leads to very small packets, hurting
performance. Interestingly, HTTP/1 frontend also suffers the same
performance hit.
