nghttpx: Handle h2 backend error per Downstream
...
Previously we wrongly handles stream per connection when h2 backend
failed or closed. If upstream is h2 or spdy, streams which are not
associated to the failed h2 backend are also handled, which is
unnecessary.

and --backend-http2-connection-window-size option to replace existing
*-bits options. The old options are not flexible because they only
specify number of bits. Now we can specify integer value, with
possible g, m, and k unit. The old options are still available for
backend compatibility, but are deprecated.

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.

We modeled max_header_fields and header_field_buffer limit from Apache

header fields, while we applied both request and response. Since
nghttpx is used as reverse proxy and backend server is relatively
"trusted", this commit removes the application to response header
fields.

nghttpx: Fix bug that causes connection failure with backend proxy URI
...
This is a regression when we introduced SSL/TLS session resumption in
HTTP/2 backend. Before the introduction of session resumption,
conn_.tls.ssl is always nullptr when connection is made to proxy. But
we have to keep conn_.tls.ssl to enable session resumption, so our
code breaks when it is reused. This commit fixes this issue.
