This commit reimplements the C# API in terms of a Wasmtime linker.
It removes the custom binding implementation that was based on reflection in
favor of the linker's implementation.
This should make the C# API a little closer to the Rust API.
The `Engine` and `Store` types have been hidden behind the `Host` type which is
responsible for hosting WebAssembly module instances.
Documentation and tests have been updated.
* Add a .gitattributes file specifying LF-style line endings.
This is similar to [Rust's .gitattributes file] though simplified.
Most of our source and documentation files already used LF-style line
endings, including *.cs files, so this makes things more consistent.
[Rust's .gitattributes file]: https://github.com/rust-lang/rust/blob/master/.gitattributes
* Remove UTF-8 BOMs in *.cs files.
Most of our *.cs files don't have UTF-8 BOMs, so this makes things more
consistent.
* Add a wasmtime-specific `wasmtime_wat2wasm` C API
This commit implements a wasmtime-specific C API for converting the text
format to the binary format. An upstream spec issue exists for adding
this to the C API, but in the meantime we can experiment with our own
version of this API and use it in the C# extension, for example!
Closes#1000
* Reorder arguments
* Use wasm_byte_vec_t for input `*.wat`
* Mark wat input as const
* Return an error message and use `fixed`
* Actually include the error message
* Use `fixed` in `Module.cs` as well
This commit implements an initial WASI C API that can be used to instantiate
and configure a WASI instance from C.
This also implements a `WasiBuilder` for the C# API enabling .NET hosts to bind
to Wasmtime's WASI implementation.
