Question: Specialized value types

The Canonical ABI uses custom representations for `string` and `flags`, rather than using the corresponding generic despecialized types. I submitted #320 with some documentation which I hope helps here.

Implement `socket_bind_device` and `set_socket_bind_device`

It looks like this has a build error in the tests on non-Linux platforms: ``` error[E0433]: failed to resolve: could not find `netdevice` in `net` --> tests/net/sockopt.rs:642:29 | 642 |...

Custom section name recommendations to avoid conflicts

There is also some discussion of this idea [here](https://github.com/WebAssembly/design/issues/1431).

Ungate start functions, and restrict args/returns.

This is also aligning with existing implementation in Wasmtime, where it's already possible to have an inner core module with a core-wasm start function, which runs at instantiation time, and...

DynamicLinking.md: add notes about memory/table exports

Create directory if not exists, and return `Dir`

Thanks. We still can't do it on Unix though. It's also worth mentioning that cap-std is following std here, where [create_dir](https://doc.rust-lang.org/stable/std/fs/fn.create_dir.html) similarly does not return a handle, presumably for the...
