std: refactor `pthread`-based synchronization The non-trivial code for `pthread_condvar` is duplicated across the thread parking and the `Mutex`/`Condvar` implementations. This PR moves that code into `sys::pal`, which now exposes an `unsafe` wrapper type for `pthread_mutex_t` and `pthread_condvar_t`. |
