35627cf37f Implement wasm trap handlers. (#27) 
* Implement wasm trap handlers.

This adds signal handlers based on SpiderMonkey's signal-handler code.
The functionality for looking up the trap code and wasm bytecode offset
isn't yet implemented, but this is a start.

I considered rewriting this code in Rust, but decided against it for now
as C++ allows us to talk to the relevant OS APIs more directly.

Fixes #15.

* Compile with -std=c++11.

* Refactor InstallState initialization.

* Compile with -fPIC.

* Factor out the code for calling a wasm function with a given index.

* Fix unclear wording in a comment.

1f8b7c31a9 Remove obsolete clippy scripts. 
Now that clippy is installable via rustup and is generally more stable,
we no longer need special scripts. `rustup component add clippy-preview` is
sufficient to install clippy, and `cargo clippy` is sufficient to run it.

Also, don't run clippy in test-all.sh. We do generally want to fix things
clippy reports, however it's not a requirement that the code be kept
clippy-warning-free at all times.

da4382802a Add a LICENSE file to published crates. 
The individual crates are published separately from the main repository
on crates.io. To ensure that a copy of the LICENSE file accompanies all
published copies of the code, give each crate its own LICENSE file.

fb7153ccf4 Update to cranelift 0.20.0. 
The biggest change is the split from FunctionIndex to
DefinedFuncIndex to FuncIndex. Take better advantage of this by
converting several Vecs to PrimaryMaps.

Also, table_addr can now handle indices of the table index type,
so we don't need to explicitly uextend them anymore.
