Tatsuhiro Tsujikawa ad3d43b8be nghttpx: Add access log variable for backend host and port
Use $backend_host and $backend_port.  $backend_host is backend host
name given in --backend option.  It could be a path to UNIX domain
socket.

Tatsuhiro Tsujikawa cbced219ec nghttpx: Rewrite read timer handling
For HTTP/2, read timer starts when there is no downstream, and timer
stops when there is at least one downstream.  For HTTP/1, read timer
starts when request handling finished, and timer stops when request
handling starts.

Tatsuhiro Tsujikawa 667c8b0e27 nghttpx: Add APIDownstreamConnection to handle API request
For those connections via frontend with api parameter, they use solely
APIDownstreamConnection.

In this commit, APIDownstreamConnection just consumes all request
body, and do nothing.  The next few commits implements our first API
endpoint: /v1/api/dynamicconfig.

Tatsuhiro Tsujikawa 58b06f32a2 nghttpx: Configure TLS per backend routing pattern
We added "tls" parameter to --backend option to enable TLS on that
backend connection.  --backend-tls options was deprecated, now is
noop.

only.

Tatsuhiro Tsujikawa 06921f35f3 nghttpx: Restructure mode settings
It is very hard to support multiple protocols in backend while
retaining multiple mode settings.  Therefore, we dropped modes except
for default and HTTP/2 proxy mode.  The other removed modes can be
emulated using combinations of options.  Now the backend connection is
not encrypted by default.  To enable encryption on backend connection,
use --backend-tls option.

Tatsuhiro Tsujikawa 21007da392 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.

Tatsuhiro Tsujikawa 03f7f8cb9c nghttpx: About implicit conversion from ImmutableString and std::string to StringRef
This is required to avoid creation of temporary ImmutableString
like so:

std::string x;
ImmutableString y = ...;
StringRef ref = !x.empty() ? x : y;

First, temporary ImmutableString is created with x since
ImmutableString has constructor to accept std::string.  After
StringRef gets this, the temporary ImmutableString is destroyed, and
ref has dangling pointer.
