Add rudimentary support for address sanitizer builds
This change adds a new setup.py option called --sanitize-address which will build all executables and shared libraries with address sanitizer enabled. The builds will only succeed on Linux and macOS machines that have new enough gcc / clang versions, so it is a "use at your own risk" build configuration. This change was necessitated by the random crashes that are sometimes observed on the CI machines, and due to valgrind not working properly on new macOS versions, using AddressSanitizer is the next best thing. Note that when running tests with address sanitizer builds, you might need to export a LD_PRELOAD / DYLD_INSERT_LIBRARIES environment variable pointing to the address sanitizer runtime library path, which will be provided by the crashed application.
