David Steele 027c263871 Add configure script for improved multi-platform support.
Use autoconf to provide a basic configure script. WITH_BACKTRACE is yet to be migrated to configure and the unit tests still use a custom Makefile.

Each C file must include "build.auto.conf" before all other includes and defines.  This is enforced by test.pl for includes, but it won't detect incorrect define ordering.

Update packages to call configure and use standard flags to pass options.
