compositor: Use libunwind if available for better backtraces
libunwind has a dwarf parser and automatically queries the dlinfo
for location of dlopened modules. The resulting backtrace is much
better and includes stack frames in dynamically loaded modules.
krh: Originally submitted for Xorg, adapted for weston:
http://lists.x.org/archives/xorg-devel/2013-February/035493.html
Note this require libunwind at least 1.1 to get the pkg-config files.
