Tatsuhiro Tsujikawa 2ec585518e Fix receiving stream data stall
Previously, if automatic window update is enabled (which is default),
after window size is set to 0 by
nghttp2_session_set_local_window_size, once the receiving window is
exhausted, even after window size is increased by
nghttp2_session_set_local_window_size, no more data cannot be
received.  This is because nghttp2_session_set_local_window_size does
not submit WINDOW_UPDATE.  It is only triggered when new data arrives
but since window is filled up, no more data cannot be received, thus
dead lock happens.

This commit fixes this issue.  nghttp2_session_set_local_window_size
submits WINDOW_UPDATE if necessary.

Tatsuhiro Tsujikawa 6ce4835eea Fix the bug that stream is closed with wrong error code
This commit fixes the bug that stream is closed with wrong error code
(0).  This happens when STREAM or DATA frame with END_STREAM flag set
is received and it violates HTTP messaging rule (i.e., content-length
does not match) and the other side of stream has been closed.  In this
case, nghttp2_on_stream_close_callback should be called with nonzero
error code, but previously it is called with 0 (NO_ERROR).

nghttp2_session_set_stream_user_data now works for a stream which is
not created yet, but the request which creates the stream is queued.

Piotr Sikora 2ba1389993 Fix handling of SETTINGS_MAX_CONCURRENT_STREAMS.
The maximum number of outgoing concurrent streams is initially
limited to 100 to avoid issues when the local endpoint submits
lots of requests before receiving initial SETTINGS frame from
the remote endpoint, since sending them at once to the remote
endpoint could lead to rejection of some of the requests.

This initial limit is overwritten with the value advertised in
SETTINGS_MAX_CONCURRENT_STREAMS setting by the remote endpoint,
but previously, it wasn't lifted if the remote endpoint didn't
advertise that setting (implying no limits), in which case the
limit of 100 was retained, even though it was never advertised
by the remote endpoint.

Tatsuhiro Tsujikawa 422ad1be32 Use NGHTTP2_REFUSED_STREAM for streams which are closed by GOAWAY
The error code NGHTTP2_REFUSED_STREAM is passed to
nghttp2_on_stream_close callback when a stream is closed because its
stream ID is strictly larger than incoming or outgoing GOAWAY.

Tatsuhiro Tsujikawa 78d7160a99 Treat incoming invalid regular header field as stream error
Previously, the incoming invalid regular header field was ignored by
default.  With this commit, they are now treated as stream error, and
the stream is reset by default.  The error code used is now
PROTOCOL_ERROR, instead of INTERNAL_ERROR.

Tatsuhiro Tsujikawa 54f4b85beb Fix nghttp2_session_want_write
This commit fixes the bug in nghttp2_session_want_write.  Previously,
it may return 0 if there is pending frames after GOAWAY frame is
submitted.

To avoid the situation that nghttp2_session_want_write keeps returning
nonzero after GOAWAY and the number of active streams is 0 (e.g., keep
receiving SETTINGS or PING), nghttp2_session_mem_recv now just
swallows the input data without parsing in this case.

Tatsuhiro Tsujikawa f3a5a0a0ec Add nghttp2_option_no_closed_streams
nghttp2_option_no_closed_streams controls whether closed streams are
retained or not.  If nonzero is passed to that function's parameter
val, a session does not retain closed streams.  It may hurt the shape
of priority tree, but can save memory.

Tatsuhiro Tsujikawa 6858cda366 Fix GOAWAY race with new incoming stream on server side
Revert part of 16c46114dc to fix race
condition that incoming stream after sending GOAWAY causes connection
error.  The strict stream handling introduced in the above commit does
not handle several cases well (e.g., GOAWAY race, and refusing streams
because of concurrency limit).
