* Support task_wait / task_wait_tid syscalls:Patrick Williams2011-10-241-4/+129
| | | | | | | | | | | | | | | | | | | | | | | | | - Add task_end2 syscall to allow pthread_exit-like retval. - Add/maintain task states. - Create task parent/child tracking tree. - Add task_detach function. - Implement wait syscalls. Make task_exec caller the parent of spawned task: Previously the task_exec call caused a message to the VFS task, which called task_create and returned the tid in response to the message. This causes the parent of the spawned task to appear to be the VFS task. Modify task_exec / VFS handling to instead return the entry point address on the message and have task_exec call task_create directly itself.
