5b76a6291e Implement Deref for all imported JS types
This commit implements the first half of [RFC #5] where the `Deref`
trait is implemented for all imported types. The target of `Deref` is
either the first entry of the list of `extends` attribute or `JsValue`.

All examples using `.as_ref()` with various `web-sys` types have been
updated to the more ergonomic deref casts now. Additionally the
`web-sys` generation of the `extends` array has been fixed slightly to
explicitly list implementatoins in the hierarchy order to ensure the
correct target for `Deref` is chosen.

56400c3738 Don't use path dependencies in examples
This commit updates all examples to not use `path` dependencies but
rather use versioned dependencies like would typically be found in the
wild. This should hopefully make the examples more copy-pastable and
less alien to onlookers!

The development of the examples remains the same where they continue to
use the `wasm-bindgen`, `js-sys`, `web-sys`, etc from in-tree. The
workspace-level `[patch]` section ensures that they use the in-tree
versions instead of the crates.io versions.

25b26f41e7 Implement support for WebAssembly threads
... and add a parallel raytracing demo!

This commit adds enough support to `wasm-bindgen` to produce a workable
wasm binary *today* with the experimental WebAssembly threads support
implemented in Firefox Nightly. I've tried to comment what's going on in
the commits and such, but at a high level the changes made here are:

* A new transformation, living in a new `wasm-bindgen-threads-xform`
  crate, prepares a wasm module for parallel execution. This performs a
  number of mundane tasks which I hope to detail in a blog post later on.
* The `--no-modules` output is enhanced with more support for when
  shared memory is enabled, allowing passing in the module/memory to
  initialize the wasm instance on multiple threads (sharing both module
  and memory).
* The `wasm-bindgen` crate now offers the ability, in `--no-modules`
  mode, to get a handle on the `WebAssembly.Module` instance.
* The example itself requires Xargo to recompile the standard library
  with atomics and an experimental feature enabled. Afterwards it
  experimentally also enables threading support in wasm-bindgen.

I've also added hopefully enough CI support to compile this example in a
builder so we can upload it and poke around live online. I hope to
detail more about the technical details here in a blog post soon as
well!

bb7271aa43 Fix our WebIDL for Safari
This commit employs the strategy described in #908 to apply a
non-breaking change to fix WebIDL to be compatible with all browsers,
including Safari.

The problem here is that `BaseAudioContext` and `AudioScheduledSourceNode`
are not types in Safari, but they are types in Firefox/Chrome. The fix
here was to move the contents of these two interfaces into mixins, and
then include the mixins in all classes which inherit from these two
classes. That should have the same effect as defining the methods
inherently on the original interface.

Additionally a special `[RustDeprecated]` attribute to WebIDL was added
to signify interfaces this has happened to. Currently it's directly
tailored towards this case of "this intermediate class doesn't exist in
all browsers", but we may want to refine and extend the deprecation
message over time.

Although it's possible we could do this as a breaking change to
`web-sys` I'm hoping that we can do this as a non-breaking change for
now and then eventually on the next breaking release batch all these
changes together, deleting the intermediate classes. This is also
hopefully a good trial run for how stable web-sys can be when it's
actually stable!

717cfa303d Fix polyfill of TextEncoder and TextDecoder
This commit does a few things, including:

* Fixing the generated JS of `wasm-bindgen` to allow polyfills to work.
  (a minor tweak of the generated JS)

* All examples are updated to include a Webpack-specific polyfill for
  these two types to get examples working in Edge.

* A new page has been added to the guide about supported browsers. This
  mentions known caveats like IE 11 requiring `wasm2js` as well as
  documenting some `TextEncoder` and `TextDecoder` workarounds for Edge.

Closes #895

bc36b6f84b Add catch(console.error) to all examples
Some examples have been failing to load in some browsers, and this
ensures that whenever the promise to load Rust code fails we log any
errors happening instead of accidentally failing silently.

97cceebe7e Update and improve crate features in web-sys
* Regenerate the list of features for the crate given recent
  improvements, enabling some more types to be bound.
* Add feature gates for the `css` and `console` namespaces (modules),
  gating the APIs by default. Now `web_sys` has zero APIs unless they're
  requested.
* Improved the "required feature" documentation for `struct` types to
  not list parent classes and mention just the `struct` type instead.

7b495468f6 Implement support for Uint8ClampedArray
This commit implements support for binding APIs that take
`Uint8ClampedArray` in JS. This is pretty rare but comes up in a
`web-sys` binding or two, and we're now able to bind these APIs instead
of having to omit the bindings.

The `Uint8ClampedArray` type is bound by using the `Clamped` marker
struct in Rust. For example this is declaring a JS API that takes
`Uint8ClampedArray`:

    use wasm_bindgen::Clamped;

    #[wasm_bindgen]
    extern {
        fn takes_clamped(a: Clamped<&[u8]>);
    }

The `Clamped` type currently only works when wrapping the `&[u8]`, `&mut
[u8]`, and `Vec<u8>` types. Everything else will produce an error at
`wasm-bindgen` time.

Closes #421

3efe51eb8b Reorganize and rewrite examples
This commit is a large-ish scale reorganization of our examples. The
main goal here is to have a dedicated section of the guide for example,
and all examples will be listed there. Each example's `README` is now
just boilerplate pointing at the guide along with a blurb about how to
run it.

Some examples like `math` and `smorgasboard` have been deleted as they
didn't really serve much purpose, and others like `closures` have been
rewritten with `web-sys` instead of hand-bound bindings.

Overall it's hoped that this puts us in a good and consistent state for
our examples, with all of them being described in the guide, excerpts
are in the guide, and they're all relatively idiomatically using
`web-sys`.

Gate web-sys APIs on activated features (#790)
* Gate `web-sys` APIs on activated features

Currently the compile times of `web-sys` are unfortunately prohibitive,
increasing the barrier to using it. This commit updates the crate to instead
have all APIs gated by a set of Cargo features which affect what bindings are
generated at compile time (and which are then compiled by rustc). It's
significantly faster to activate only a handful of features vs all thousand of
them!

A magical env var is added to print the list of all features that should be
generated, and then necessary logic is added to ferry features from the build
script to the webidl crate which then uses that as a filter to remove items
after parsing. Currently parsing is pretty speedy so we'll unconditionally parse
all WebIDL files, but this may change in the future!

For now this will make the `web-sys` crate a bit less ergonomic to use as lots
of features will need to be specified, but it should make it much more
approachable in terms of first-user experience with compile times.

* Fix AppVeyor testing web-sys

* FIx a typo

* Udpate feature listings from rebase conflicts

* Add some crate docs and such
