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 bytecodealliance#15.

This code is now functional on Linux at least. I haven't tested Mac or Windows yet, though the C++ code this is based on support these platforms, so if anyone tries these before I have a chance to, please report any problems! |

Merging now as this is laying more infrastructure to build on. |
