tor-cell: Refactor relay cells to copy much less

2023-02-15T15:48:19Z

We now manipulate raw relay cell bodies as (an alias for) `Box<[u8;509]>` rather than as (an alias for) `[u8;509]`. This enables us to do much less copying. It will become more important soon, as we defer parsing relay cell bodies even longer. Related to #7. We also use SliceWriter to avoid allocating a Vec<> for every relay message we want to encode, and instead encode directly into the cell.

tor-cell: Make RelayEarly a separate type.

2023-02-09T15:20:28Z

This allows us to remove a shenanigan from `restricted_msg!{}`.

cell: Parameterize ChannelCodec::decode and encode.

2023-02-09T13:26:09Z

This change lets us use ChannelCodec to encode and decode any restricted channel message type we want. (Later on, we'll turn the related Codec class in tor-proto into a more type-restricted version of this.)

tor-cell: Rename RelayMsg and RelayCell-related types.

2023-02-07T21:03:14Z

Thanks to rust-analyzer for making this simple.

tor-cell: Rename ChanMsg and ChanCell-related types.

2023-02-07T21:03:14Z

tor-cell: Remove RelayMsg methods that are duplicated in RelayMsgClass.

2023-02-07T21:03:14Z

tor-cell: Remove ChanMsg methods that are duplicated in ChanMsgClass.

2023-02-07T21:03:14Z

tor-cell: Use macro to generate ChanMsg too.

2023-02-07T21:03:14Z

tor-cell: Change all variants of RelayMsg to have a body.

2023-02-07T21:03:14Z

Previously, there were some unit variants, but that makes things quite awkward for #525.

tor-cell: Make Body and MsgClass traits more uniform.

2023-02-07T21:03:14Z

Doing this will make it much easier to implement a macro that generates restricted instances of the Msg types (for #525). The Body change is a breaking change. I don't think anybody else implements Body, but in theory they could.
