Upgrade renameutils to version 0.12.0.
Adjust one of the three patches for the new file structure.
Add a fourth patch to fix a Makefile syntax error that would cause
`make install` to fail. Reported upstream via email and fixed in
HEAD. Taken from HEAD but not applied directly to `Makefile.am`.
Apply it to `Makefile.in` so there's no need for new deps on
autotools.
Tested on Lion using clang and llvm from XCode-4.3.3.
