The disconnect message could either be a plain integer, or a list with
one integer element. We were encoding it as a plain integer, but
decoding as a list. Change this to be able to decode any format.

Refactor this idea to a common place.
* better naming: MarshalPubkey matches existing UnmarshalPubkey
* "Std" suffix for the ANSI standard encoding without cut off
* docs
This change moves the RLPx protocol implementation into a separate package,
p2p/rlpx. The new package can be used to establish RLPx connections for
protocol testing purposes.
