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: Feed read event rather than calling on_read
...
on_read may fail, but we failed to check its return value most of the
places. This is because failure means deletion of ClientHandler, but
because of architecture, we cannot delete it. Feeding read event is
better since we can move call on_read from libev callback. We can
delete ClientHandler form there.

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.

nghttpx: New error log format
...
To debug multi threaded configuration easier, we added current PID and
thread ID to error log. Previously, we didn't add date and time if
log level is NOTICE. In this change, we always write date and time
regardless of log level.

nghttpx: Just return DNS_STATUS_ERROR
...
At the moment, we use both resolvers, and if either one is not
DNS_STATUS_IDLE, the other one is also not DNS_STATUS_IDLE. This may
change if we are going to configure DNS so that either A or AAAA
lookup is done. In that case, it is better to just return
DNS_STATUS_ERROR in the diff. This is because the calling side does
not expect DNS_STATUS_IDLE in that case.

nghttpx: Lookup backend host name dynamically
...
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.

nghttpx: Wait for child process to exit
...
Normally, we don't have wait for child process to exit, since init can
take care of them. But in containerized environment, pid 0 init might
not be available, and defunct processes can be piled up. This commit
ensures that OCSP and neverbleed processes are waited for before
worker process exits.
