execution of wasm programs across different hardware/circumstances.
This is very useful for Blockchain projects having wasm smart-contracts
This is critical for Blockchain projects that require execution to be deterministic
in order to reach a consensus of the state transition of each smart-contract transaction.
807: Implement Send for Instance r=MarkMcCaskey a=MarkMcCaskey
# Review
- [x] Create a short description of the the change in the CHANGELOG.md file
Resolves#748
WIP
## List of changes
### Commit 1
- `Global`s use Arc instead of RC
- Export `Context` and `FuncPointer` manually implement Send
- `ImportObject` uses `Arc<Mutex<HashMap<...>>>` Instead of `Rc<RefCell<HashMap<...>>>`; removed `get_namespace` method in favor of continuation style to deal with locking the Mutex
- `Func` manually implements `Send` (TODO: this change needs to be checked in depth)
### Commit 2
- `unsafe impl Send for Export {}` (temporary to allow Memory to be not Send)
- RefCell -> Mutex in Global and Table
- Rc -> Arc in Table
- Namespace's `IsExport`s must be `Send` (Done to avoid touching much more of the code (i.e. `trait IsExport: Send` requires a lot -- maybe this is what we should do though)
- Make `Host` and `Wasm` `Func`s Send (manual implementation)
- Manual implementation for `LocalTable` and `AnyFunc`
### Commit 3
- rm placeholder `unsafe impl Send for Export {}`
- Manual implementation for `LocalBacking` and `ImportBacking` (both seemed to be not Send due to direct ownership of mutable pointers in their containers)
- ImportObject's state creator Fn trait object is now ` + Send + Sync + 'static` (required because it's in an Arc)
- Manually implement Send for `InstanceInner` because it holds a raw pointer, `LocalBacking` and `ImportBacking` are marked Send separately
- Memory: All Rc -> Arc (including unshared memory); All RefCell -> Mutex (including unshared memory)
- Manual implementation of Send and Sync on `UnsharedMemoryInternal`
- Manual implementation of Send and Sync on `SharedMemoryInternal`
- Change `runtime-core::unix::memory::Memory.fd` from `Option<Rc<Rawfd>>` to `Option<Arc<Rawfd>>` (not strictly required for this change because Memory has manual implementations of Send and Sync, but Arc seems more correct here and there's no comment justifying the use of Rc)
- Manual implementation of Send for `ImportedFunc`

821: Remove patch version in deps when not necessary r=MarkMcCaskey a=MarkMcCaskey
This allows wasmer library users to have more control over the exact versions of deps that Wasmer uses.
# Review
- [x] Add a short description of the the change to the CHANGELOG.md file
Co-authored-by: Mark McCaskey <mark@wasmer.io>
803: Add method to call function at index on Ctx r=MarkMcCaskey a=MarkMcCaskey
For #638 and #670
```Rust
fn call_guest_fn(ctx: &mut Ctx, guest_fn: u32) -> u32 {
println!("{}", guest_fn);
let guest_fn_typed = unsafe { std::mem::transmute(guest_fn) };
let result = ctx.call_with_table_index(guest_fn_typed, &[]).unwrap();
println!(" -> {:?}", result);
0
}
```
is what this looks like from the Host side
See `examples/callback.rs` for an example that doesn't require `transmute`

805: Replace panic! & unimplemented! in runtime-code and llvm-backend r=nlewycky a=pventuzelo
# Description
Replace `unimplemented!` by already used `CodegenError` in `lib/llvm-backend/src/code.rs`
Replace `unimplemented!` by `Err` in `lib/llvm-backend/src/trampolines.rs`
Replace `panic!` by already used `BinaryReaderError` in `lib/runtime-core/src/parse.rs`

When the colored output was originally added in https://github.com/wasmerio/wasmer/pull/489 and there was a discussion then about that it should ideally be in a higher-level crate rather than in the runtime-core library crate.
I agree with that, users of the library shouldn't be required to bring in the colored crate dependency and ideally also not have stdout/stderr output either, that should be controlled by the application that uses wasmer-runtime-core, not the library.
Disabling stdout/stderr output would be more intrusive but I wanted to at least not have colored output and another crate dependency so this change removes the colored output and the "colored" crate.
