Add "reindent" target to top-level Makefile.in. Add

krb5-batch-indent.el.  These perform a batch reindent based upon the
Emacs file-local variable settings, taking care to distinguish between
files that are supposed to conform to the coding style versus those
that are marked as being exceptions.  A later commit will explicitly
mark the files that we expect to conform to our coding standards.
