Tatsuhiro Tsujikawa 7bfa276e96 Fix bug that NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE causes session failure
Previously returning NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE from
on_header_callback moves input offset badly and it causes header
decompression error on the subsequent frames.  This commit fix this
bug.

Tatsuhiro Tsujikawa 00ead22395 Don't allow frame submission for pending new frame
This is partial revert of bbe4f5a3d1.
Only documentation is reverted.  Since we have 2 queues to handle
maximum concurrent streams, we are not ready to allow immediate frame
submission for pending new frames.

Tatsuhiro Tsujikawa bbe4f5a3d1 Allow frame submission immediately after nghttp2_submit_{request,headers,pp}
This commit makes handling of outgoing HEADERS and PUSH_PROMISE in the
same priority of other frames on the stream, so these frames are
processed in the order they are submitted.  This allows application to
submit frames to a stream returned by nghttp2_submit_{request,
headers, push_promise} immediately.  The only exception is
WINDOW_UPDATA frame, which requires nghttp2_stream object, which is
not created yet.

Tatsuhiro Tsujikawa 8d5422c9bb Remove check for incoming header block size

Tatsuhiro Tsujikawa 079db14d45 Add nghttp2_session_consume() API
Reworked no automatic WINDOW_UPDATE feature.  We added new API
nghttp2_session_consume() which tells the library how many bytes are
consumed by the application.  Instead of submitting WINDOW_UPDATE by
the application, the library is now responsible to submit
WINDOW_UPDATE based on consumed bytes.  This is more reliable method,
since it enables us to properly send WINDOW_UPDATE for stream and
connection individually.  The previous implementation of nghttpx had
broken connection window management.

Tatsuhiro Tsujikawa 55c697e9f4 Handle multiple SETTINGS_HEADER_TABLE_SIZE in incoming SETTINGS frame
Previously we just assumed that if same settings ID is found in
SETTINGS, it is enough to process last seen entry.  But it turns out
it is not enough for SETTINGS_HEADER_TABLE_SIZE.  If we have 0 and
4096 for SETTINGS_HEADER_TABLE_SIZE in one SETTINGS, we must first
shrink dynamic table to 0 and then enlarge it to 4096.  This means
that we have to remember the minimum value and last value.

Tatsuhiro Tsujikawa 6da044cbb5 Send WINDOW_UPDATE for ignored DATA bytes when manual flow control is enabled
Since we do not call on_data_chunk_recv_callback for ignored DATA
chunk, if nghttp2_option_set_no_auto_connection_window_update is used,
application may not have a chance to send connection WINDOW_UPDATE.
To fix this, we accumulate those received bytes, and if it exceeds
certain number, we automatically send connection-level WINDOW_UPDATE.

option to change this upper bound in the future.

Tatsuhiro Tsujikawa 31de732e3b Allocate header table ringbuffer lazily
Previously in inflater we reserve new ringbuffer when table size is
changed.  This may be potentially a problem if new table size is very
large number.  When inflater is not used directly by application, this
is not a problem because application can choose the buffer size.  On
the other hand, if application uses inflater directly and it does not
have control of new buffer size (e.g., protocol dissector), then we
just fail to allocate large buffer in
nghttp2_hd_inflate_change_table_size() without actually use such huge
buffer.  This change defers the actual allocation of buffer when it is
actually needed so that we will fail when it is absolutely needed.

Tatsuhiro Tsujikawa dacc9b2f1c Separate extension frames from core frames
ALTSVC and BLOCKED frames are now extension frames.  To add new
extension frame without modifying nghttp2_frame union, which causes so
name bump, we separated extension frames from core frames.
nghttp2_frame includes generic nghttp2_extension.  The payload member
of nghttp2_extension will point to the structure of extension frame
payload.  The frame types of extension frames are defined in
nghttp2_ext_frame_type.
