Kernel: Dump backtrace to debugger for DefaultSignalAction::DumpCore.

Browse source 
This makes assertion failures generate backtraces again. Sorry to everyone
who suffered from the lack of backtraces lately. :^)

We share code with the /proc/PID/stack implementation. You can now get the
current backtrace for a Thread via Thread::backtrace(), and all the traces
for a Process via Process::backtrace().
