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: documentation cleanups related to restricted_msg

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

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.

tor-cell: Generic "Restricted{Relay,Chan}Cell" types.

2023-02-07T21:03:14Z

These are generalizations of RelayCell and ChanCell respectively, that allow using an arbitrary message type in place of the fully general RelayMsg and ChanMsg types. Doing this is a prerequisite for usefully implementing arti#525.

tor-cell: Make historical comments more concrete

2022-10-21T10:59:26Z

This commit extends comments that make references to historical protocol versions of Tor, by adding the concrete protocol version numbers.

Move all crates into a `crates` subdirectory.

This will cause some pain for now, but now is really the best time to do this kind of thing.
