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.

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.

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.
