Tatsuhiro Tsujikawa a7c780a732 nghttpx: Redirect to HTTPS URI with redirect-if-not-tls param
This commit removes frontend-tls parameter, and adds
redirect-if-not-tls parameter parameter to --backend option.  nghttpx
now responds to the request with 308 status code to redirect the
request to https URI if frontend connection is not TLS encrypted, and
redirect-if-no-tls parameter is used in --backend option.  The port
number in Location header field is 443 by default (thus omitted), but
it can be configurable using --redirect-https-port option.

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 1dabe43ff4 nghttpx: Workaround for std::make_shared bug in Xcode7, 7.1, and 7.2
std::make_shared in Xcode 7, 7.1, and 7.2 does not perform
value-initialization, and causes undefined behaviour if struct does
not have user defined default constructor.  This workaround explicitly
defines user defined default constructor, and initializes values.

Tatsuhiro Tsujikawa 2a4733857f nghttpx: Reduce TTFB with large number of incoming connections
To reduce TTFB with large number of incoming connections, we now
intentionally accept one connection at a time, so that it does not
delay the TTFB of the existing connection.  This is significant
especially for TLS connections.

Tatsuhiro Tsujikawa fd801864e3 nghttpx: Add sni keyword to --backend option
The --backend-tls-sni-field is deprecated in favor of sni keyword.
--backend-tls-sni-field still works, and it overrides all sni keyword
in --backend option.  But it will be removed in the future release.

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.
