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.

28aea5c6b7 nghttp_hd: Use huffman encoding only when it is usable 
We use huffman encoding only when its encoded length is strictly less
than the original length.
As noted in the HPACK draft, the length of name/value is now 7-bit
prefix and its MSB is 1 if the following string is huffman encoded.

f7389ff2e6 Revert 622b05aa3131d646038522e762e90b1b4ea3b917 
It turns out that 0-bit prefix is wrong, and the author now
clearly stated that the intention is 8-bit prefix for 8+ fields.

of the headers. It also becomes one-pass encoder.
