common: remove old RLP implementation, Value and ExtPackage

In order to make this happen, kill all remaining trivial uses of
common/{rlp,value}.go. The non-trivial ones have been updated earlier.

-// Value can hold values of certain basic types and provides ways to

-// conversion is actually meaningful.
-//
-// It currently supports the following types:

-//    - int{,8,16,32,64}
-//    - uint{,8,16,32,64}
-//    - *big.Int

-//
-// Value is useful whenever you feel that Go's types limit your
-// ability to express yourself. In these situations, use Value and
-// forget about this strong typing nonsense.
