24cb90806d Add flags to nghttp2_nv structure 
This is preliminary change for upcoming HPACK updates.  The flags are
used to determine the name/value pair is indexable or not.

1fee4fd2df nghttp2_hd: Fail inflate immediately if ctx.bad is nonzero 
Doing inflation after error produces invalid results, especially, if
it is in NGHTTP2_HD_STATE_READ_INDEX, the inflater->left could be 0,
which causes assertion error.  Add sanity assertion for index

9314e30987 Support transmission of CONTINUATION, change nghttp2_frame_hd 
The maximum frame size including header block is still limited
to NGHTTP2_HD_MAX_BUFFER_LENGTH, which is 32KB.

8317559090 nghttp2_hd: Implement stream header inflater 
This stream inflater can inflate incoming header block in streaming
fashion. Currently, we buffer up single name/value pair, but we chose
far more smaller buffer size than HTTP/2 frame size.

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.

9eb031ce83 nghttp2_hd: Avoid nghttp2_hd_huff_decode_count 
Huffman decoding is costly. It is faster to do geometric realloc
than calling nghttp2_hd_huff_decode_count to know the length in
advance.

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.

40347487c9 Don't sort headers in library code 
Remove sorting headers from library code. The application must sort
them if necessary. nghttpx and nghttpd do the sorting of the headers
in stable way if names are equal.
