This series adds Android backtrace support, which is a prerequisite for using the refcount debugging tool in gallium. It also comes in handy for impromptu debug outputs.
Unfortunately, it wasn't possible to reuse the existing libunwind implementation. The only sanctioned way for obtaining backtraces on Android is through their own, C++ only libbacktrace.
