Rework `init` and `cleanup` This PR reworks the code in `std` that runs before and after `main` and centralizes this code respectively in the functions `init` and `cleanup` in both `sys_common` and `sys`. This makes is easy to see what code is executed during initialization and cleanup on each platform just by looking at e.g. `sys::windows::init`. Full list of changes: - new module `rt` in `sys_common` to contain `init` and `cleanup` and the runtime macros. - `at_exit` and the mechanism to register exit handlers has been completely removed. In practice this was only used for closing sockets on windows and flushing stdout, which have been moved to `cleanup`. - ~~On windows `alloc` and `net` initialization is now done in `init`, this saves a runtime check in every allocation and network use.~~
