This commit adds a `#[link]` annotation to the block defining symbols coming from a native static library that we build and link. This is required by rustc to get symbols to get exported correctly when linking wasmtime into a Rust dynamic library instead of always as an rlib. While I was at it I went ahead and renamed the symbols now that they're no longer in C++ and they're doing setjmp/longjmp and not much else. Closes #3006
This is the wasmtime-runtime crate, which contains wasm runtime library
support, supporting the wasm ABI used by wasmtime-environ,
wasmtime-jit, and wasmtime-obj.
This crate does not make a host vs. target distinction; it is meant to be compiled for the target.
Most users will want to use the main wasmtime crate instead of using this
crate directly.
