Forgot to add pub_core_redir.h when committing the m_redir module.

+// PURPOSE: This module deals with:
+// - code redirection: intercepting calls to client functions, and
+// pointing them to a different piece of code.
+// - function wrapping: add calls to code before and after client
+// functions execute, for inspection and/or modification.
+//
+// Nb: It's possible that this should be two modules.
