* Add examples of linking and WASI

This commit adds two example programs, one for linking two modules
together and one for instantiating WASI. The linkage example
additionally uses WASI to get some meaningful output at this time.

# Embedding in C
This section is intended to showcase the C embedding API for Wasmtime. The C
embedding API is based on the [proposed wasm C embedding API][proposal] (namely
[`wasm.h`]) and has a few extension headers (like [`wasi.h`] and
[`wasmtime.h`]) which are intended to eventually become part of the standard
themselves one day.
[proposal]: https://github.com/webassembly/wasm-c-api
[`wasm.h`]: https://github.com/WebAssembly/wasm-c-api/blob/master/include/wasm.h
[`wasi.h`]: https://github.com/bytecodealliance/wasmtime/blob/master/crates/c-api/include/wasi.h
[`wasmtime.h`]: https://github.com/bytecodealliance/wasmtime/blob/master/crates/c-api/include/wasmtime.h
