wireprotoserver: access headers through parsed request
Now that we can access headers via the parsed request object, let's
do that.
Since the new object uses bytes, hyphens, and is case-insensitive, a
bit of code around normalizing values has been removed. I think
the new code is much more intuitive because it more closely matches
what is going out over the wire.
