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.

encode_length: Or-ing first byte with prefix mask

So that we can preserve leading bits.

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.
