RPC: Functionality to downcast dyn Object to a dyn Trait.

2023-06-12T17:35:28Z

This is a rather tricky piece of functionality. It works as follows. We introduce a `CastTable` type. Each `CastTable` tells us how to downcast `dyn Object` for objects of a single concrete type. The `Object` type now has a `get_casttable` method that returns an empty `CastTable` by default. `CastTable` is, internally, a map from the `TypeId` of the target dyn Trait reference type to a function `fn(&dyn Object) -> &dyn Trait`. These functions are stored as `Box`. (They are Boxed because they may refer to generic functions, which you can't get a static reference to, and they're Any because the functions have different types.) The `decl_object!` macro now implements `get_casttable` as appropriate. (The syntax is a bit janky, but that's what we get for not using derive_adhoc.) For non-generic types, `get_casttable` uses a Lazy`. to initialize a CastTable exactly once. For generic types, it use a `Lazy>` to build one CastTable per instantiation of the generic type. This could probably be optimized a bit more, the yaks could be shaved in a more scintillating hairstyle, and the syntax for generic `decl_object` could definitely be improved.

rpc: Remove downgrade_owned for now

2023-05-24T14:15:56Z

Rationale: Our weak-vs-strong design is a bit confused at the moment due to concerns about deduplication and capability semantics. It's not clear that a general "change strong to weak" method is compatible with what we want to provide.

rpc: Implement functionality to remove objects from a session

2023-05-24T14:15:56Z

I've made doing some design choices here: * Reserving "rpc" as a prefix for post-authentication functionality that is not arti-specific. * Declaring these to be methods on the session rather than methods on the objects themselves. There's a problem with defining an API to drop a weak reference; see comment in code.

Arti: Add ability to remember the list of methods names.

2023-04-19T16:38:26Z

Right now, this lets us say whether the method was unrecognized or whether the parameter type was incorrect. We'll use this to enforce correct method names later on. (I have to add another `inventory` here, since the `typetag` maintainer does not want to expose this functionality: see https://github.com/dtolnay/typetag/issues/57#issuecomment-1506106290 )
