6fa1a084f7 A shareable atomically reference counted pointer wrapper. 
Needs more tests to ensure safety, and probably some more work on usability too.

4871f11439 std: change timeval to ns resolution timespec 
This lets us use the more precise clock_gettime on posix
machines.

7aae7320db std: change time::timeval to be {sec: i64, usec: i32}. 
It's possible to have negative times if expressing time before 1970, so
we should use signed types. Other platforms can return times at a higher
resolution, so we should use 64 bits.

33a949eed6 Add global rust_get_current_task 
Previously two methods existed: rust_sched_loop::get_task and rust_task::get_task_from_tcb. Merge both of them into one, trying the faster one (tcb) first, and if that fails, the slower one from the tls.

35ba9715fa core: Add task::spawn_sched 
This function creates a new scheduler with a specified number of threads and
immediately executes a task on it. The scheduler is configured to terminate
when the task dies. This is the minimum API necessary to enable blocking C
calls.
