This PR updates `wasmtime_wasi` crate by adjusting `poll_oneoff`'s
signature to that introduced in `wasi_common` in
CraneStation/wasi-common#137. This change is required in order to
fix#440.
* Switch lightbeam from `wabt` to `wast`
Switch from a C++-based `*.wat` parser to a Rust-based parser
* Remove unneeded `wabt` dev-dependency from wasmtime-api
* Rewrite `wasmtime-wast` crate with `wast-parser`
This commit moves the `wasmtime-wast` crate off the `wabt` crate on to
the `wast-parser` crate which is a Rust implementation of a `*.wast` and
`*.wat` parser. The intention here is to continue to reduce the amount
of C++ required to build wasmtime!
* Use new `wat` and `wast` crate names
* deps: bump wasmparser to 0.39.2
This has a bug fix for multi-value Wasm validation that is required for getting
the spec tests passing.

* Update cranelift to 0.46.1 to get multi-value Wasm support
The `cranelift_wasm` APIs had to change a little bit to maintain state necessary
when translating multi-value Wasm blocks. The `translate_module` function now
returns a `ModuleTranslationState` that is borrowed during each function's
translation.
* Enable multi-value proposal's spec tests
This enables all the Wasm multi-value proposal's spec tests other than the ones
that rely on functions having more return values than registers available on the
target. That is not supported by cranelift yet.
* wasmtime-interface-types: always use multi-value Wasm
And remove the return pointer hacks that work around the lack of multi-value.
This adds a `--always-lightbeam` option as well as an `--always-cranelift`
option, to allow the compilation strategy to be selected via the
command-line. This also enables regular testing for Lightbeam.
This fixes the memory leaks in the following functions which should not be
returning "owned" pointers:
* `wasm_extern_as_func`
* `wasm_func_as_extern`
* `wasm_extern_as_global`
* `wasm_global_as_extern`
* `wasm_extern_as_memory`
* `wasm_extern_as_table`
Additionally, this commit implements the `wasm_memory_as_extern` and
`wasm_table_as_extern` functions.
Fixes#394.
This commit implements populating the table imports of a module from the API.
It also allows for `anyref` in table types as per the reference types proposal.
This PR fixes the borrow scope of store in the `WrappedCallable` impl of
`WasmTimeFn` such that it does not remain borrowed across the call to
`wasmtime_call_trampoline`. By limiting the scope of the borrow, the
implementation can be reentered if an exported function calls an imported
function, which in turn calls another exported function.
Fixes#365.
