data, if the packed data is contiguous and the unpacked one is not. The
problem was that the unpack function did not update the bConverted value
to the real number of bytes extracted from the iovecs, but limit the update
to the number of bytes moved into the user buffers. So, if there were some
bytes copied in the internal pending buffer, they were lost because the next
convertor instead of using the correct bConverted (with the total number of
bytes) has only the transfered number. The result of this bug, is a shift to
left by few bytes of the values in the user buffers.
Add a protection against such kind of errors in the new_position.c.

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

increased the datatype ref count, and there is no way to have a convertor without a valid
request, so there is no need for the convertor to increase the reference count of the datatype
again. Therefore, if one want to use the datatype for something else than MPI request, one
has to manage the reference counts outside the datatype layer.

the same algorithm as in the zlib library, as it is supposed to be the fastest
one and still give good error detection. For those who want to activate the
checksum, there is a define at the bottom of the datatype_internal.h file.

- Separate out the registration of the MCA params into a standalong
function that is invoked by ompi_mpi_init() (so that ompi_info can
see these params)
- Rename the params to "mpi_ddt_*" instead of "datatype_*" so that
they fit into the common naming scheme
This commit was SVN r8196.
Remove the old function from the dt_unpack.c and activate the new one from dt_copy.c
Add a MCA param ompi_copy_debug to get messages about the local memory copies in the new function.
Slightly change the prototype of the function to keep the compilers happy on some platforms.

This flag is inherited by all datatypes create with unavailable datatypes. Basically, we let the user create the wrong datatype but we dont let him using it for any pt2pt communications or any pack/unpack.

Limit the amount of data to be packed to the remaining on the convertor. This make the things a lot simpler in the pack/unpack functions.

Do not ignore the type and extent of the last optimized basic type in some special cases.
Update the last fake END_LOOpP with the correct value for the first_elem_disp field.

never stored on the stack. It is partially stored on the stack depending on the loops
but every time we pack/unpack a basic datatype we take in account again it's displacement.
This approach make the whole logic a lot simpler. In same time I split the big functions
in several basic block.

- if the alignment of wchar is zero then wchar_t is not supported by the OS. We skip it.
- Now that the definition of end_loop change compute the first_elem_description for all
predefined datatypes.
- In debug mode print a list of the datatypes that are not supported by the current
architecture.
