Implement `super`, mostly.
...
We implement `super` by way of a new `Object` impl which wraps arbitrary objects with a modified prototype chain. Specifically, the lowest layer of the prototype chain is omitted. This new `SuperObject` script is composable: a chain of two `SuperObject`s will go two levels of inheritance upwards while still maintaining non-prototype property access.

Calling uncallable values does not actually cause a runtime error in Flash; it just returns null.
...
This was discovered almost by accident: @Dinnerbone noticed that `_global == null`, and surmised that `valueOf` was the culprit. However, this doesn't really make sense: `_global` is a bare object, so it shouldn't have a `valueOf` (and in practice, it doesn't).
The ultimate cause of such an odd comparison is as such:
1. Flash coerces the `_global` object to a numerical primitive by calling `valueOf`.
2. `_global.valueOf` is undefined. Flash handles calls to any uncallable value by literally just having it return `undefined`. In other words, all values are implicitly callable as empty functions.
3. `undefined` is then compared to `null`. These two values *are* equal under abstract equality (`==`). Hence, `_global == null`.
For comparison, modern ECMAScript engines throw errors on calls to uncallable values; and won't attempt to use an invalid `valueOf` to coerce objects. So none of this applies to, say, standard JavaScript in your browser.

Implement ECMAScript compliant type coercions.
...
This includes ECMA-262 2ed `ToNumber`, `ToPrimitive` (Number), `ToString`, and abstract equality and less-than implementations. Note that `ToPrimitive` is only the "number hint" variant, and Flash specifically *never* calls `toString` like how ECMA-262 specifies.
Several builtins inherit numerical coercion - I'm not 100% sure if that's correct.
The following ActionScript opcodes now perform ECMA-262 style coercions:
`ActionAdd2` (uses `valueOf` / "ToPrimitive hint Number")
`ActionDecrement` (uses `valueOf`)
`ActionEquals2` (uses `valueOf`)
`ActionGetMember` (member names, uses `toString`)
`ActionIncrement` (uses `valueOf`)
`ActionLess2` (uses `valueOf`)
`ActionGreater` (uses `valueOf`)
`ActionSetMember` (member names, uses `toString`)
`ActionStringEquals` (uses `toString`)
`ActionStringGreater` (uses `toString`)
`ActionStringLess` (uses `toString`)
`ActionToNumber` (uses `valueOf`)
`ActionToString` (uses `toString`)
`ActionTrace` (uses `toString`)
The following functions now gained user-specified coercions via `toString`:
`_global.number` (uses `valueOf`)
`_global.is_nan` (uses `valueOf`)
Every function in `Math` (uses `valueOf`)

Implement prototype chain recursion limit of 255 prototypes.
...
In Flash, this also at least claims to halt ActionScript execution on the movie. No such implementation of AVM poisoning currently exists in Ruffle, primarily because it's unclear what gets poisoned and implementing some of these options isn't yet possible:
1. AVM (e.g. all movies) - we would need to make the AVM fail silently in this case. This is the most straightforward way to poison the movie, but I'm not sure if this is how Flash actually does it, or if it poisons...
2. Movie - the current structure of movies is incompatible with adding arbitrary data to them. We need to merge `moviefetch` in before we can attach data to loaded movies.
3. MovieClip - this would also be implementable but has problems. How do child MovieClips know that their parent has been poisoned, or vice versa? What if a movie clip is loaded from one movie and moved into another?
As a result, I have decided to hold off on implementing recursion poisoning until I know where it's supposed to go and how to implement that.

Separate `Object` into an interface trait and a standard implementation. Host object implementations may bypass `ScriptObject` and directly interface with the AVM using this trait.
...
Note that host objects that do so will *not* have access to their standard representation from within member functions - you will need to extend the interface to accomodate for them. This is due to long-standing limitations with type IDs and downcasting with types that bear lifetimes - it's entirely an unsafe operation and exposing such a facility to safe Rust is unsound. However, this will at least let us separate out several things from ScriptObject that don't need to be there for the time being.

Allow overwriting read-only virtual properties in scope chains.
...
The previous behavior had an oversight: if you tried to set a variable with the same name as an in-scope property, it would always try to overwrite that property. This can fail silently and doesn't match with Flash Player behavior. Now, an attempt to overwrite a read-only property is instead correctly rejected so that it can be defined in local scope.

Replace `Option<Value<'gc>>` with a dedicated `ReturnValue<'gc>` type with associated methods.
...
This type explicitly signals if an immediate value is to be returned, if a value is to be returned on the stack, or if no return value is to be generated. Holders of a `ReturnValue` can also use `and_then` to schedule a `StackContinuation` to be executed when and if that value is ready.
`StackContinuations` now yield `ReturnValues` as well, so they have a moderate level of composability. For example, if you need to get a property from an object and push it on the stack, you can return the result of calling `get` directly and the machinery ensures it eventually gets there.

Allow getters to resolve on the AVM1 stack.
...
This involved yet another macro, `and_then!`, to avoid a ridiculous amount of duplicate code. It calls a continuation whenever it's value is ready, even if the value resolved on the Rust stack.
`locals_into_form_values` does not currently support this. It skips any property that does not resolve on the Rust stack. Future work is required to resolve this.

Ensure that the value of the newly constructed `this` is returned in all cases.
...
This involves the use of a "stack continuation" system. Due to previous lifetime issues with using closures directly (see `8ea6c6234dba925ec5fbc61502627fb62b05916c`), we instead use a macro that constructs a `Collect`able type holding the things the continuation needs to continue working with. The syntax is largely similar to Rust closures but with the addition of an explicit list of bound variables, all of which must be `Collect`.

core: Stop stream sound when gaps are encountered
...
Generally there is one SoundStreamBlock per frame in a MovieClip.
However, if there are gaps between stream sounds, the stream must
stop and then pick up when the next block is encountered.
TODO: Sometimes Flash will do weird stuff and export a stream that
is plainly out of sync if there are gaps between sounds (the old
trick was to put a silent stream across the entire timeline to fix
this). This happens when the streams are too close together with
MP3 encoding. Investigate this more.

text: Add dummy implementation of device text
...
Embed an SWF version of Noto Sans (core/assets/*) into the player.
The player will load this font and use it to render device text.
This is a quicky implementation to get dynamic device text
rendering.
