Use libbacktrace for stack trace printing

libbacktrace-static.x86_64                   13.2.0-7.azl3        azurelinux-official-base

extern int backtrace_full (struct backtrace_state *state, int skip,
			   backtrace_full_callback callback,
			   backtrace_error_callback error_callback,
			   void *data);

Something to consider, probably.

Apparently the embedded snippet stuff only works in the same repo, unfortunately.
