Tatsuhiro Tsujikawa 0e4b3d435e Emit header name/value pair using callback functions
Now, in nghttp2_on_frame_recv_callback, nva and nvlen in
HEADERS and PUSH_PROMISE frames are always NULL and 0 respectively.
The header name/value pairs are emitted successive
nghttp2_on_header_callback functions. The end of header fields are
signaled with nghttp2_on_end_headers_callback function.

Since NGHTTP2_ERR_PAUSE for nghttp2_on_frame_recv_callback is
introduced to handle header block, it is now deprecated.
Instead, nghttp2_on_header_callback can be paused using
NGHTTP2_ERR_PAUSE.

Tatsuhiro Tsujikawa 41104f7b63 Abandon DATA frame priority adjustment (again)
We tried several times about this subject, but for the current
HTTP/2.0 priority scheme, we think it is best to serve the highest
priroty streams first (interleaving streams if there are several
higest ones). There are an issue when aggregating several frontend
connections to one connection in backend, but it is HTTP/2.0
spec issue, rather than implementation.

Tatsuhiro Tsujikawa 364501a2cd Get rid of magic value NGHTTP2_PRI_DECAY
For now we just double the priority value on each DATA frame
transmission. If priority is 0, it becomes to 1 and goes all
the way to (1 << 30) - 1.

Tatsuhiro Tsujikawa 1dea4e154b Reintroduce priority adjustment for DATA frame
This mechanism existed but was deleted. We bring it back in order to
prevent lower priority streams from starving.

Tatsuhiro Tsujikawa d0d0009a50 Use largest valid stream ID which passed to callback as last-stream-ID
Previously we use largest stream ID received so far as last-stream-ID,
and it is irrevant that it is passed to the callback (thus upper layer).
Now the stream ID which is passed to callback is eligible to
last-stream-ID.

Tatsuhiro Tsujikawa 2ae788eddd Replace nghttp2_set_option with nghttp2_session_{client,server}_new2
nghttp2_session_client_new2 and nghttp2_session_server_new2 take
additional parameters which specifies session options.
nghttp2_set_option is somewhat crumsy because of type checking.
Now we use nghttp2_opt_set, which specifies individual options with
types. We changed the value of nghttp2_opt, so this change will
require re-compile.

Tatsuhiro Tsujikawa 4bc44b0c0b Implement SETTINGS_ENABLE_PUSH
It is not clear that SETTINGS_ENABLE_PUSH = 0 disallows HEADERS
to the reserved streams. For now, we just check the reception
and transmission of PUSH_PROMISE against SETTINGS_ENABLE_PUSH.

Tatsuhiro Tsujikawa a4cf37306a Enfoce flow control error strictly
Now we have SETTINGS synchronization, flow control error can be
detected strictly. If DATA frame is received with length > 0 and
current received window size is equal to or larger than local
window size (latter happens when we shirnk window size), it is
subject to FLOW_CONTROL_ERROR,

Tatsuhiro Tsujikawa 21d76dcc75 Add nghttp2_session_continue API function
The NGHTTP2_ERR_PAUSE library error code is introduced to pause
the execution of nghttp2_session_mem_recv() when that error code
is returned from nghttp2_on_frame_recv_callback or
nghttp2_on_data_chunk_recv_callback. If this happens, the parameters
available for both callbacks are retained until the application
calls nghttp2_session_continue(). The application must retain
input bytes which was used to produce the frame.
After successful call of nghttp2_session_continue, the application
can continue to call nghttp2_session_mem_recv() to process
additional data.
