Tatsuhiro Tsujikawa 4fa150c494 nghttpx: Use Memchunk based read buffer for frontend connection
Previously, we have dedicated read buffer for each frontend
connection.  With this commit, the buffer spaces are only used when
needed, and pooled if they are not used.  This reduces memory usage
for idle client connections.

Tatsuhiro Tsujikawa 9c7e54d9b5 nghttpx: Add client-ciphers option
Previously, ciphers option sets cipher list for both frontend and
backend TLS connections.  With this commit, ciphers option only sets
cipher list for frontend connections.  The new client-ciphers option
sets cipher list for backend connection.

Tatsuhiro Tsujikawa 3c03024881 nghttpx: Add client-no-http2-cipher-black-list option
This commit adds client-no-http2-cipher-black-list option to disable
enforcement of HTTP/2 cipher black list on backend HTTP/2 connection.
Previously, existing no-http2-cipher-black-list option disables it for
both frontend and backend connections.  Now no-http2-cipher-black-list
option only disables it for frontend connection.

Tatsuhiro Tsujikawa 0abc220013 nghttpx: Fix the bug that no-http2-cipher-black-list does not work
Because of the redundant check in backend HTTP/2 session,
no-http2-cipher-black-list does not work on backend HTTP/2 connection.
This commit fixes it.

Tatsuhiro Tsujikawa b313386988 nghttpx: Add proxyproto to frontend option to accept PROXY protocol
Previously, global accept-proxy-protocol option enables PROXY protocol
support for all frontend listeners, but this was inflexible.  To fix
this issue, accept-proxy-protocol option is now deprecated, and
instead proxyproto parameter in frontend option enables PROXY protocol
support per frontend.

Plain write(2) is OK, but SSL_write requires same arguments on retry.
It would be better to avoid calling them again.

Tatsuhiro Tsujikawa 3d20c2dce6 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.

Tatsuhiro Tsujikawa a0ce5ea9ab 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.

Tatsuhiro Tsujikawa 049e064e28 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.

Tatsuhiro Tsujikawa fd403a85c8 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.

Tatsuhiro Tsujikawa 38b5cad4e3 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.

Tatsuhiro Tsujikawa 85ba33c08f 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.
