Alex Crichton afd980b4f6 Refactor the internals of Func to remove layers of indirection (#1363) 
* Remove `WrappedCallable` indirection

At this point `Func` has evolved quite a bit since inception and the
`WrappedCallable` trait I don't believe is needed any longer. This
should help clean up a few entry points by having fewer traits in play.

* Remove the `Callable` trait

This commit removes the `wasmtime::Callable` trait, changing the
signature of `Func::new` to take an appropriately typed `Fn`.
Additionally the function now always takes `&Caller` like `Func::wrap`
optionally can, to empower `Func::new` to have the same capabilities of
`Func::wrap`.

* Add a test for an already-fixed issue

Closes #849

* rustfmt

* Update more locations for `Callable`

* rustfmt

* Remove a stray leading borrow

* Review feedback

* Remove unneeded `wasmtime_call_trampoline` shim

Examples of the wasmtime API

This directory contains a number of examples of using the wasmtime API from different languages. Currently examples are all in Rust and C using the wasmtime crate or the wasmtime embedding API.

Each example is available in both C and in Rust. Examples are accompanied with a *.wat file which is the wasm input, or a Rust project in a wasm folder which is the source code for the original wasm file.

Rust examples can be executed with cargo run --example $name, and C examples need to be compiled using your system compiler and appropriate header files.

For more information see the examples themselves!
