Carp and Confess in XS

[ #9850 ]

XS supports warn() and croak() using varargs style parameters (not a lot of XS newbies know that, but it's very useful). But XS doesn't support carp() and confess(), because getting backtraces in C has previously only been the realm of the debugger.

However I just discovered the glibc backtrace functions. Very interesting indeed.
