4c8bc19ad2 rt: Refactor task failure to go through rust_task_fail 
This is the place to but a breakpoint. We will raise SIGINT here
to break into the debugger.

9604544e23 rt: Don't log in the stack switching failure path 
The runtime is in an uncertain state here and, instead of thinking
about how to make the logger work correctly, let's just avoid it.

Currently, it ends up hitting an assert saying that we can't log on
the rust stack.

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.

marshalling them between threads anymore.

1c7a62c93b Use a memset upcall to zero things without static alignment 
This fixes issues #843 and #1546. The cost of an upcall is
unfortunate, though. I assume there must be a way to simply manually
compute the pointer or size, using something akin to the formula in
`align_to` in `rust_util.h`. I could not get this to work,
unfortunately.
