# Description
This PR removes the dependency of a Backend in runtime-core. So it's agnostic and more backends can be plugged in easily.
Why this is important?
* By removing backends from wasmer-runtime-core we can make the runtime agnostic, so anyone can plug their own backend into Wasmer without needing to touch the main source code (V8, JavascriptCore, wasm3, ...).
* It simplifies the codebase and avoids code leaks from the backend to the runtime API.

1128: fix(runtime-core) Avoid crashing when missing host functions are allowed r=Hywan a=Hywan
Fix#1118. #1121 can be merged after
This PR fixes 2 things:
* When droping the import backing, check that `vm::FuncCtx` isn't null before dropping it,
* Use an `always_trap` as a placeholder host function when a host function is missing.

1123: feat(runtime-c-api) Define the `DEPRECATED` C macro. r=Hywan a=Hywan
This PR defines a cross-compiler `DEPRECATED(message)` macro. It must
be used as follows in Rust:
```rust
/// This is a documentation.
/// cbindgen:prefix=DEPRECATED("This is a deprecation message.")
pub extern "C" fn wasmer_foo() -> c_uint {
42
}
```
It will generate the following C header:
```c
/**
* This is a documentation.
*/
DEPRECATED("This is a deprecation message.")
unsigned int wasmer_foo();
```
And once this code is used by a C compiler, it will print something
like this (example from Clang):
```
…/test.c:…:…: error: 'wasmer_foo' is deprecated: This is a deprecation message. [-Werror,-Wdeprecated-declarations]
unsigned int x = wasmer_foo();
^
…/wasmer.h:…:…: note: 'wasmer_foo' has been explicitly marked deprecated here
DEPRECATED("This is a deprecation message.")
^
…/wasmer.h:…:…: note: expanded from macro 'DEPRECATED'
```
This is required for further deprecations.
