Tatsuhiro Tsujikawa 3785cf07ba Add simple HTTP/2 extension framework
Application can utilize this framework to send/receive user defined
extension frames.  These frames are expected not to change existing
protocol behaviour.

Tatsuhiro Tsujikawa 45d4c9dece Add new error code NGHTTP2_ERR_PAUSE to send_data_callback
If application returns NGHTTP2_ERR_PAUSE from send_data_callback, it
means application processed all data, but wants to make
nghttp2_session_mem_send or nghttp2_session_send return immediately.
This is useful if application writes to fixed sized buffers, and there
is no room to write more data.

Tatsuhiro Tsujikawa d22ced77c0 Return fatal error if flooding is detected to close session immediately
This change adds new return error code from nghttp2_session_mem_recv
and nghttp2_session_recv functions, namely NGHTTP2_ERR_FLOODED.  It is
fatal error, and is returned when flooding was detected.

Tatsuhiro Tsujikawa 2d5b42693d Don't expect NULL terminated name/value in nghttp2_hd_deflate_hd
If it is called through libnghttp2 internally, name/value pairs are
all NULL-terminated.  But it is one of public API, and we cannot
expect that applications always make NULL-terminated string for
name/value pairs.

Tatsuhiro Tsujikawa 928a81885c Limit the number of incoming reserved (remote) streams
RFC 7540 does not enforce any limit on the number of incoming reserved
streams (in RFC 7540 terms, streams in reserved (remote) state).  This
only affects client side, since only server can push streams.
Malicious server can push arbitrary number of streams, and make
client's memory exhausted.  The new option,
nghttp2_set_max_reserved_remote_streams, can set the maximum number of
such incoming streams to avoid possible memory exhaustion.  If this
option is set, and pushed streams are automatically closed on
reception, without calling user provided callback, if they exceed the
given limit.  The default value is 200.  If session is configured as
server side, this option has no effect.  Server can control the number
of streams to push.

Tatsuhiro Tsujikawa 059280d1a5 Add stream public API
The intention of this stream API is give server application about
stream dependency information, so that it can utilize it for better
scheduling of stream processing.  We have no plan to add object
oriented API based on stream object.

Tatsuhiro Tsujikawa 5b59e46e2b Rewrite priority handling
We now use priority queue per stream, which contains the stream which
has ready to send a frame, or one of its descendants have a frame to
send.  We maintain invariant that if a stream is queued, then its
ancestors are also queued (except for root).  When we re-schedule
stream after transmission, we re-schedule all ancestors, so that
streams on the other path can get a chance to send.  This is basically
the same mechanism h2o project uses, but there are differences in the
details.

Tatsuhiro Tsujikawa d1e49a196d Remove restriction in regard to number of stream in dependency tree
Previously, the number of stream in one dependency tree (not including
root) is limited to 120.  This is due to the fact that we use
recursive calls to traverse trees.  Now we replaced recursive calls
with loop, we can remove this limitation.  Also now all streams are
descendant of root stream, rather than linked list of individual
subtree root.

Tatsuhiro Tsujikawa f3288092e8 Strictly check occurrence of dynamic table size update
RFC 7541 requires that dynamic table size update must occur at the
beginning of the first header block, and is signaled as SETTINGS
acknowledgement.  This commit checks these conditions.  If dynamic
table size update appears other than the beginning of the first header
block, it is treated as error.  If SETTINGS ACK is received, and next
HEADERS header block does not have dynamic table size update, it is
treated as error.

Tatsuhiro Tsujikawa c70cfe64c4 Fix DATA is not consumed if nghttp2_http_on_data_chunk failed
This commit fixes the bug that DATA is not consumed if
nghttp2_http_on_data_chunk is failed.  It also simplify the handling
of missing stream in NGHTTP2_IB_READ_DATA state.

Tatsuhiro Tsujikawa 693fba3b64 Add more docs about NGHTTP2_ERR_DATA_EXIST and its condition
This commit documents NGHTTP2_ERR_DATA_EXIST also occurs if HEADERS
has been already attached to stream too.  This commit also fixes
possible assertion error, and now nghttp2_submit_headers() and
nghttp2_submit_response() may return NGHTTP2_ERR_DATA_EXIST.  But we
recommend to use nghttp2_submit_request() and
nghttp2_submit_response(), and using them will avoid this error.
