Fixes to get ast_backtrace working properly. The AST_DEVMODE macro was never defined so the majority of ast_backtrace never
attempted compilation. The makefile now defines AST_DEVMODE if configure was run with --enable-dev-mode. Also, changes were 
made to acccomodate 64 bit systems in ast_backtrace.

Thanks to qwell, kpfleming, and Corydon76 for their roles in allowing me to get this committed
