How do people feel about the following compromise:

1) Increase frame size to 16-bits.
2) Remove reference set from HPACK allowing for "streaming" decoding.
3) Requiring that all ":"-headers appear first.
4) Only allowing CONTINUATION if the previous frame is 2^16-1 bytes.
5) Allowing interleaving of CONTINUATION frames with other frames.

For implementors that know that they will never accept more than 64kb
of headers, they don't have to implement CONTINUATION frames.

For implementors that are concerned about not receiving routing
headers and having to buffer full frames, they will be the first
things that show up and the rest of the headers can be proxied without
any buffering.

For implementors that need to support headers > 64kb they can do so
using CONTINUATION frames.

For implementors concerned about interleaving headers between multiple
streams, that is now allowed because the reference set does not
coincide with the end of the header block.

For implementors that are concerned with spec complexity, the entire
notion of "header block fragments" is removed.
