Rust implementation of C's `va_list` type

# Overview
This crate provides a rust `VaList`type, which is binary-compatible for the C `va_list` type. It is intended to allow rust code to provide the complex logic of variable argument functions.

# Example
```rust
extern crate va_list;
use va_list::VaList;

extern "C" print_ints_va(count: u32, mut args: VaList)
{
	for i in (0 .. count) {
		println!("{}: {}", i, args.get::<i32>());
	}
}
```

# Status
- x86_64 ELF (aka System-V)
  - Linux: CI tested, and used in the wild
- `aarch64` ELF: Minimal testing
  - Unix (not macos)
- `cdecl32` 32-bit: Minimal testing
  - Unix x86/arm32
  - Windows
- `cdecl` 64-bit: CI tested
  - macos amd64
  - Windows
  - Unix riscv64
  - unix `loongarch64`
