This commit moves the libserialize crate (and will force the hand of the rustc-serialize crate) to not require the `old_orphan_check` feature gate as well as using associated types wherever possible. Concretely, the following changes were made: * The error type of `Encoder` and `Decoder` is now an associated type, meaning that these traits have no type parameters. * The `Encoder` and `Decoder` type parameters on the `Encodable` and `Decodable` traits have moved to the corresponding method of the trait. This movement alleviates the dependency on `old_orphan_check` but implies that implementations can no longer be specialized for the type of encoder/decoder being implemented. Due to the trait definitions changing, this is a: [breaking-change]

This commit moves the libserialize crate (and will force the hand of the
rustc-serialize crate) to not require the
old_orphan_checkfeature gate aswell as using associated types wherever possible. Concretely, the following
changes were made:
EncoderandDecoderis now an associated type, meaningthat these traits have no type parameters.
EncoderandDecodertype parameters on theEncodableandDecodabletraits have moved to the corresponding method of the trait. This movement
alleviates the dependency on
old_orphan_checkbut implies thatimplementations can no longer be specialized for the type of encoder/decoder
being implemented.
