9e50ae46d9 nghttp_hd: Use NGHTTP2_HD_SIDE_{REQUEST,RESPONSE} instead of {CLIENT,SERVER} 
This change conveys better notion about compression context.

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.

4dcf9ad4f2 Make hd encoder ordering aware and one-pass 
The encoder algorithm is simplified and it now preserves ordering
of the headers. It also becomes one-pass encoder.

091f38a99d Revise common header processing 
Instead of emitting common headers on decoder side, encoder
now keeps track of removed common headers and encode it
as necessary.
