util: introduce util.debugstacktrace for showing a stack trace without crashing

This is often very handy when hacking/debugging.

Calling util.debugstacktrace('hey') from a place in hg will give something like:
  hey at:
   ./hg:38                                     in <module>
   /home/user/hgsrc/mercurial/dispatch.py:28   in run
