c9b6371977 When assertions is disable, there is a warning about unused check_index_range function 
Make the check for a valid index range a macro, so the compiler doesn't
whine if it's not used, but it's available if it *is* used.

d113055899 nghttp2_hd: Use single buffer for an name/value pair 
Previously we use 2 separate buffer for each name and value.  The
problem is we would waste buffer space for name because it is usually
small.  Also tuning buffer size for each buffer separately is not
elegant and current HTTP server practice is that one buffer for 1
name/value pair.  This commit unifies 2 buffers into 1.

ab76468971 Return NGHTTP2_ERR_BUFFER_ERROR from nghttp2_hd_{deflate,inflate}_hd 
It is generally useful to know what is the cause of the error.  Since
we expose HPACK API, it is friendly to tell application the
insufficient buffer size is a culprit.

1fee4fd2df nghttp2_hd: Fail inflate immediately if ctx.bad is nonzero

it is in NGHTTP2_HD_STATE_READ_INDEX, the inflater->left could be 0,
which causes assertion error.  Add sanity assertion for index

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

advance.
