CarpetIOHDF5: implement parallel I/O

Like CactusPUGHIO/IOHDF5, CarpetIOHDF5 now also provides parallel I/O for
data and checkpointing/recovery.
The I/O mode is set via IOUtils' parameters IO::out_mode and IO::out_unchunked,
with parallel output to chunked files (one per processor) being the default.
The recovery and filereader interface can read any type of CarpetIOHDF5 data
files transparently - regardless of how it was created (serial/parallel,
or on a different number of processors).

See the updated thorn documentation for details.
