Alex Crichton 0bee67a852 Document and update the API of the externals.rs module (#812 )

* Document and update the API of the `externals.rs` module

This commit ensures that all public methods and items are documented in
the `externals.rs` module, notably all external values that can be
imported and exported in WebAssembly. Along the way this also tidies up
the API and fixes a few bugs:

* `Global::new` now returns a `Result` and fails if the provided value
  does not match the type of the global.
* `Global::set` now returns a `Result` and fails if the global is either
  immutable or the provided value doesn't match the type of the global.
* `Table::new` now fails if the provided initializer does not match the
  element type.
* `Table::get` now returns `Option<Val>` instead of implicitly returning
  null.
* `Table::set` now returns `Result<()>`, returning an error on out of
  bounds or if the input type is of the wrong type.
* `Table::grow` now returns `Result<u32>`, returning the previous number
  of table elements if succesful or an error if the maximum is reached
  or the initializer value is of the wrong type. Additionally a bug was
  fixed here where if the wrong initializer was provided the table would
  be grown still, but initialization would fail.
* `Memory::data` was renamed to `Memory::data_unchecked_mut`.
  Additionally `Memory::data_unchecked` was added. Lots of caveats were
  written down about how using the method can go wrong.
* `Memory::grow` now returns `Result<u32>`, returning an error if growth
  fails or the number of pages previous the growth if successful.

* Run rustfmt

* Fix another test

* Update crates/api/src/externals.rs

Fuzzing Infrastructure for Wasmtime

This crate provides test case generators and oracles for use with fuzzing.

These generators and oracles are generally independent of the fuzzing engine that might be using them and driving the whole fuzzing process (e.g. libFuzzer or AFL). As such, this crate does not contain any actual fuzz targets itself. Those are generally just a couple lines of glue code that plug raw input from (for example) libFuzzer into a generator, and then run one or more oracles on the generated test case.

If you're looking for the actual fuzz target definitions we currently have, they live in wasmtime/fuzz/fuzz_targets/* and are driven by cargo fuzz and libFuzzer.
