He did get core's approval and core did require some changes to the
import. We did ask why not sys/external and other things.  Given the
reasons given, we thought sys/lib/libunwind was the best place so it
can be used both in the kernel and userland.

If you've ever looked at the stacktrace code for ARM or MIPS, any
alternative would be better than the existing code.  Being able to
-fomit-stack-pointer for performance and still get a ddb stacktrace
is also a win.
