Temporarily fixed warnings in printf in dmtcp_restart.cpp
- For some reason, the methods that return addresses are returning
  long unsigned ints (starting at line 333).  I would have expected that they
  should return 'void *', in which case, the original declaration (%p)
  would have worked.  We shouldn't rely on 'void *' and 'long unsigned int'
  always being the same size.  There are architectures where that's not true.
