3879f6f427 Introduce the wasm-bindgen-webidl frontend
This is still a work in progress. Parse WebIDL source text and convert it into
wasm-bindgen AST, so that we can automatically emit bindings for the types and
functions described in the WebIDL.

dd76707ea1 Prevent use-after-free with vectors
Awhile back slices switched to being raw views into wasm memory, but this
doens't work if we free the underlying memory unconditionally! Moving around a
`Vec` is already moving a lot of data, so let's copy it onto the JS heap instead
of leaving it in the wasm heap.

237fff0698 Map u64/i64 to BigInt in JS
This commit is an implementation of mapping u64/i64 to `BigInt` in JS through
the unstable BigInt APIs. The BigInt type will ship soon in Chrome and so this
commit builds out the necessary support for wasm-bindgen to use it!

48a823c685 Remove slice logic of "commit to wasm"
When adding support for mutable slices I was under the impression that if the
wasm memory was reallocated while we were using it then we'd have to commit the
changes from the original buffer back to the new buffer. What I didn't know,
however, is that once the wasm memory is reallocated then all views into it are
supposed to be defunkt.

It looks like node 9 didn't have this implementation quite right and it appears
fixed in node 10, causing the deleted test here to fail. While this commit does
raise the question of whether this is the right approach to interact with slices
in JS I think the answer is still "yes". The user can always initiate the copy
if need be and that seems strictly better than copying 100% of the time.

139b7a1aae Don't use the global stack for string lengths
This commit updates the `Abi` associated type for all slice types to a
`WasmSlice` type, an aggregate of two `u32` integers. This translates to an ABI
where when passed as a function argument it expands to two integer arguments,
and when passed as a return value it passes a return pointer as the first
argument to get filled in.

This is hopefully more forwards-compatible with the host bindings proposal which
uses this strategy for passing string arguments at least. It's a little sketchy
what we're doing as there's not really a stable ABI yet, but hopefully this'll
all be relatively stable for awhile!

0566a97485 Add support for mutable slices
This commit adds support for mutable slices to pass the boundary between JS and
Rust. While mutable slices cannot be used as return values they can be listed as
arguments to both exported functions as well as imported functions.

When passing a mutable slice into a Rust function (aka having it as an argument
to an exported Rust function) then like before with a normal slice it's copied
into the wasm memory. Afterwards, however, the updates in the wasm memory will
be reflected back into the original slice. This does require a lot of copying
and probably isn't the most efficient, but it should at least work for the time
being.

The real nifty part happens when Rust passes a mutable slice out to JS. When
doing this it's a very cheap operation that just gets a subarray of the main
wasm memory. Now the wasm memory's buffer can change over time which can produce
surprising results where memory is modified in JS but it may not be reflected
back into Rust. To accomodate this when a JS imported function returns any
updates to the buffer are copied back to Rust if Rust's memory buffer has
changed in the meantime.

Along the way this fixes usage of `slice` to instead use `subarray` as that's
what we really want, no copying. All methods have been updated to use `subarray`
accessors instead of `slice` or constructing new arrays.

Closes #53

dadcff15ef Add an example of wasm2asm and wasm-bindgen
This commit adds an example of executing the `wasm2asm` tool to generate asm.js
output instead of WebAssembly. This is often useful when supporting older
browsers, such as IE 11, that doesn't have native support for WebAssembly.

4a873af8d1 Enable cargo test where possible
Currently `#[wasm_bindgen]` generates a bunch of references to symbols that
don't actually exist on non-wasm targets, making it more difficult to get a
crate working across multiple platforms. This commit updates the symbol
references to be dummy ones that panic on non-wasm targets to allow simple
testing/benchmarking to work on native targets.

While this isn't a perfect solution for #114 it's probably as good as we can do
for now pending upstream Cargo features, so I'm gonna say that it...

b8895b3a95 Add JsValue::{from_serde, into_serde}
These functions are activated with the `serde-serialization` feature of the
`wasm-bindgen` crate. When activated they will allow passing any arbitrary value
into JS that implements the `Serialize` trait and receiving any value from JS
using the `Deserialize` trait. The interchange between JS and Rust is JSON.

Merge pull request #165 from jryans/spans-feature
Add `spans` feature to control `proc-macro2`

11e274b477 Add spans feature to control proc-macro2
Using `proc-macro2`'s `nightly` feature is a good default for most use cases.
However, it causes a build error if used together with crates such as
`cssparser` that also use `proc-macro2` from a build script.

This change adds a default enabled feature `spans` that users can disable if
they need to work around this conflict.

Fixes #160.
