Message:

Merge the stack tracing branch.

The merge includes generic and amd64 and ia32 support for kernel stack traces.
The kernel will now print a stack trace for each killed task and also for
each bad trap and panic. The rest of the architectures have dummy support,
i.e. they compile and run, but the kernel cannot print the stack trace.
