Tatsuhiro Tsujikawa e453759637 Add nghttp2_option_set_no_auto_ping_ack() option
This option prevents the nghttp2 library from sending PING frame with
ACK flag set in the reply to incoming PING frame.  To allow the
application to send PING with ACK flag set, nghttp2_submit_ping() now
recognizes NGHTTP2_FLAG_PING in its flags parameter.

Peter Wu 63e43bff99 tests: remove unused macros
Since v0.6.2-7-g1d138ac ("Unify DATA and other frames in
nghttp2_outbound_item and save malloc()"), the macros are unused and the
builds fails on -Werror=unused-macros.

Tatsuhiro Tsujikawa 4a78f59e7b Rename nghttp2_session.sent_stream_id as last_sent_stream_id
This is more accurate, and there is symmetric relation between
last_sent_stream_id and last_recv_stream_id, which is bettern fit in
my sense.

Tatsuhiro Tsujikawa 4ceb9fd767 Cancel stream if flow control window gets overflow
Previously, we did terminate session, but it did not actually cancel
streams.  Now we just cancel streams in this case.

Tatsuhiro Tsujikawa bb6f842b37 Check request/response submission error based side of session
Disallow request from server, and response from client respectively.
When the violation is detected, return NGHTTP2_ERR_PROTO from
nghttp2_submit_request, nghttp2_submit_response,
nghttp2_submit_headers.

We also did some refactoring, and now self-dependency detection is
placed where it is only required.

Tatsuhiro Tsujikawa 9cea986819 Strict outgoing idle stream detection
Previously, we use session->next_stream_id to detect that given stream
ID was idle or not.  But this was suboptimal, since it was updated
when stream ID was assigned, and it did not necessarily mean that it
actually has been sent to the peer.  Now we introduced
session->sent_stream_id, which only updated when HEADERS/PUSH_PROMISE
has sent.  Using sent_stream_id instead of next_stream_id tightens
idle stream detection, and misbehaved peer which sends frame with
stream ID that has not been generated.

This commit also overhauls test code which involves opening streams.
Now we have some wrapper functions for nghttp2_session_open_stream()
which also take care of updating next_stream_id and
last_recv_stream_id.  They are crucial for some tests.

Tatsuhiro Tsujikawa 8716dd05d4 Return error from nghttp2_submit_{headers,request} when self dependency is made
Return NGHTTP2_ERR_INVALID_ARGUMENT from nghttp2_submit_headers() if
given stream ID and pri_spec->stream_id are the same (thus trying to
depend on itself).

Also return NGHTTP2_ERR_INVALID_ARGUMENT from nghttp2_submit_request()
and nghttp2_submit_headers() with stream_id == 1, when new stream ID
equals to pri_spec->stream_id.

Previously, these cases are not checked, and just sent to peer.

Tatsuhiro Tsujikawa 894c1bd02e Create idle stream on client side
With the presence of idle stream related API (e.g.,
nghttp2_create_idle_stream()), it is more predictable for client to
create idle streams with its dependency to another idle stream.
Previously, we didn't create complete parent idle stream in this case.
Now we create idle streams as we do on server side.

Tatsuhiro Tsujikawa 2288ee8060 Create stream object for pushed resource during nghttp2_submit_push_promise()
Previously, stream object for pushed resource was not created during
nghttp2_submit_push_promise().  It was created just before
nghttp2_before_frame_send_callback was called for that PUSH_PROMISE
frame.  This means that application could not call
nghttp2_submit_response for the pushed resource before
nghttp2_before_frame_send_callback was called.  This could be solved
by callback chaining, but for web server with back pressure from
backend stream, it is a bit unnecessarily hard to use.

This commit changes nghttp2_submit_push_promise() behaviour so that
stream object is created during that call.  It makes application call
nghttp2_submit_response right after successful
nghttp2_submit_push_promise call.

Tatsuhiro Tsujikawa f23e34fa3c Handle response in nghttp2_on_begin_frame_callback
Previously, nghttp2_session_end_request_headers_received assumes
stream is still writable (in other words, local endpoint has not sent
END_STREAM).  But this assumption is false, because application can
send response in nghttp2_on_begin_frame_callback.  Probably, this
assumption was made before the callback was introduced.  This commit
addresses this issue.  Since all
nghttp2_session_end_*_headers_received functions are identical, we
refactored them into one function.

stream.  Now it is corrected, and it returns root stream as
documented.

later.  Possibly feature bloat.

Tatsuhiro Tsujikawa 269a100081 Add nghttp2_session_upgrade2(), deprecate nghttp2_session_upgrade()
To validate actual response body length against the value declared in
content-length response header field, we first check request method.
If request method is HEAD, respose body must be 0 regardless of the
value in content-length.  nghttp2_session_upgrade() has no parameter
to indicate the request method is HEAD, so we failed to validate
response body if HEAD is used with HTTP Upgrade.  New
nghttp2_session_upgrade2() accepts new parameter to indicate that
request method is HEAD or not to fix this issue.  Although, this issue
affects client side only, we deprecate nghttp2_session_upgrade() in
favor of nghttp2_session_upgrade2() for both client and server side.

Tatsuhiro Tsujikawa 5e7e479c6c Workaround HTTP upgrade with HEAD request
By default, we check the length of response body matches
content-length.  For HEAD request, this is not necessarily true, so we
sniff request method, and if it is HEAD, make sure that response body
length is 0.  But this does not work for HTTP Upgrade, since
nghttp2_session_upgrade() has no parameter to tell the request method
was HEAD.  This commit disables this response body length validation
for the stream upgraded by HTTP Upgrade.  We will add new version of
nghttp2_session_upgrade with the parameter to pass the request method
information so that we can handle this situation properly.
