Integrated H5Part regression test and fixed numerous errors that it discovered.

Finished integrating H5Block and the Fortran interface (untested).
Started adding an H5Block regression test with a few simple tests (all pass).
Added automatic detection of stripe information on lustre, and config option to compile against lustre API.
Moved buffers for H5Block ghost zone disolving out of the file handle and into the h5b_3d_set_view function.
Fixed bug with pointers in the H5Fed file data not being initialized to NULL.
