Add simple interceptors for dup, dup2, dup3.
Add an interceptor for waitpid, and rewrite the interceptor for wait to use the SimpleWrapper.
Add an interceptor for POSIX access().
Add interceptors for strcasecmp and strncasecmp.
Store the path to SeeC's resource directory in instrumented Modules, so that we can try to load resources in the runtime library.
