| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change refactors the existing create_thread() function to be more generic. It replaces almost all of its arguments by a callback that can be used to extract the thread ID and copy it out to the right place, but also to perform additional initialization steps, such as setting the trapframe. This also makes the difference between thr_new() and thr_create() more clear in my opinion. This function is going to be used by the CloudABI compatibility layer.
