* Basic changes for RISC-V support
* RISC-V in compiler LLVM
* RISC-V support in dylib engine
* RISC-V support in universal engine
* Various small fixes
* [RISCV] LLVM-riscv working, with some ignored tests to be worked on later
* Update rustc to 4.65 (1.64 has some issue with riscv64 target)
* Fixed some (new) Linting issues
* Updated Cargo.toml and remove split-debuginfo for Windows build
* Removed profile.dev from Cargo.toml as it cannot be per platform (breaks Windows). split-debug info is now the default value
* Enable Cranelift compiler for RISCV
* Update crates and fixed all the new clippy errors
* Taken review remarks into account
* Removed change from deny.toml, it's not needed anymore
* Added some more comment about llvm abi hack
* Added doc about current state of RISCV support
* Fixed (newer) linter

This change adds a basic coredump generation after a WebAssembly trap
was entered. The coredump includes rudimentary stack / process debugging
information.
A new CLI argument is added to enable coredump generation:
```
wasmer --coredump-on-trap=/path/to/coredump/file module.wasm
```
See docs/en/examples-coredump.md.
Refs https://github.com/wasmerio/wasmer/issues/3578
- Implemented multi-threading for both JS and SYS, plus other WASIX implementations
- Added a longjmp capability required for bash and other WASIX implementations
- Added real signals to WASIX
- Added a stack unwinding and winding functionality
- Implemented memory forking which will be used for process forking
- Added the ability to fork the current process
- Added the vfork functionality
- Moved over to the WasiPipe implementation
- Added more syscalls needed for bash on WASIX
- Ported wasmer-os into wasmer
- Added a union file system and the character devices
- Moved the cursors to the file handles rather than the file so that they are multithread safe and can handle concurrent IO
- Reimplemented the poll_oneoff functionality to support full ASYNC
- Added support for mapping directories in the host file system into WASIX sandbox file systems
- Implemented fully ASYNC sockets and emulated ASYNC files
- Made the file locks more granular to allow for concurrent poll and accept operations
- Fixed a race condition on the event notifications
The Universal type was essentially a builder of engines that's given a
compiler backend and creates an Engine with .engine() method. The name
was not clear.
