configure: Add --enable-sanitize-address
--enable-sanitize-address makes sure that all code is compiled with
-fsanitizer=address and all tests run against libasan.
It can be combined with --enable-sanitize-undefined, but not with
--enable-valgrind.
In maintainer mode there is one program that causes leaks, i386_gendis,
so disable leak detection for that program.
One testcase, test_nlist, needs special linker flags, make sure it also
uses -fsanitizer=address when using the address sanitizer.
