* Preserve full native stack traces in errors This commit builds on #759 by performing a few refactorings: * The `backtrace` crate is updated to 0.3.42 which incorporates the Windows-specific stack-walking code, so that's no longer needed. * A full `backtrace::Backtrace` type is held in a trap at all times. * The trap structures in the `wasmtime-*` internal crates were refactored a bit to preserve more information and deal with raw values rather than converting between various types and strings. * The `wasmtime::Trap` type has been updated with these various changes. Eventually I think we'll want to likely render full stack traces (and/or partial wasm ones) into error messages, but for now that's left as-is and we can always improve it later. I suspect the most relevant thing we need to do is to implement function name symbolication for wasm functions first, and then afterwards we can incorporate native function names! * Fix some test suite assertions
