The generic pointer decoder did not advance the input position
for empty values. This can lead to strange issues and even
infinite loops.

I don't see why we would need two different accessors for a public field.

This makes Value 24 bytes smaller on 64bit systems.

Value.{Encode,Decode} are gone. It implements rlp.Encoder and rlp.Decoder
instead, so Value can be decoded into directly.

This seems to be the last remaining use of it.

I have rewritten the protocol test to use p2p.MsgPipe because
p2p.NewMsg is gone.

This is better because protocols might not actually read the payload for
some errors (msg too big, etc.) which can be a pain to test with the old
behaviour.

This helps a lot with debugging.

Message encoding functions have been renamed to catch any uses.
The switch to the new encoder can cause subtle incompatibilities.
If there are any users outside of our tree, they will at least be
alerted that there was a change.

NewMsg no longer exists. The replacements for EncodeMsg are called
Send and SendItems.

The encoder was missing a special case for one element strings whose
element is below 0x7f. Such strings must be encoded as a single byte
without a string header.
