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 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 94ec4dbe42 nghttpd_hd: Update static table and use 1-based index
The specification now says that index to the header table entry is
1-based. Since 0-based index is very handy to access arrays, we
internally uses 0-based index. We just convert it to 1-based when
we emit to the block and convert 1-based to 0-based on decoding.

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.

window size (latter happens when we shirnk window size), it is
subject to FLOW_CONTROL_ERROR,

prefix and its MSB is 1 if the following string is huffman encoded.

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.
