Not a lot of attention has been paid to dealing with conflicts of symbols
between crates and different
#[wasm_bindgen]
blocks. This commit starts to fixthis issue by unblocking #486 which first ran into this. Currently there's a bug
where if two independent crates bind the same JS API they'll generate the same
symbol which causes conflicts for things like LTO or linking in general.
This commit starts to add a "salt" to all symbols generated by
wasm-bindgen
(these are all transparent to the user) to ensure that each crate's invocations
are kept apart from one another and using the correct bindings.
