This is implemented by re-computing the allactive bboxset that dh::regrid
computes and outputting only the part of each component that intersects
allactive. This changes the number of components since the intersection
might be non-rectangular-box.

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.

Replace all CVS header tags with the standard "$Header:$".

generic IOUtil filereader interface (see testsuite input_initial_data.par).

* better general error checking and reporting
- check return code of HDF5 API calls
- replace asserts with CCTK_VWarns of level 0 or 1 where appropriate
- don't just assert (0) if no valid checkpoint file was found
* allow relaxed recovery mode (don't stop, only warn about variables which
don't exist at recovery time)
* MPI optimizations: gather lots of individual MPI_Bcasts into a single one
for each datatype
Tested with CarpetIOHDF5's checkpointing/recovery testsuite.
In case of problems, it should be easy to roll back to the previous state:
the old code is still there in iohdf5chckpt_recover.cc.
Things left to do:
* merge recovery and filereader code
* review of checkpointing code
* rename I/O parameters
* reduce the set of attributes to a minimum
