Bring "shape same" changes from LBL branch to trunk. These changes
allow shapes that are the same, but projected into dataspaces with different
ranks to be detected correctly, and also contains code to project a dataspace
into greater/lesser number of dimensions, so the I/O can proceed in a faster
way.
These changes also contain several bug fixes and _lots_ of code
cleanups to the MPI datatype creation code.
Many other misc. code cleanup are included as well...
Tested on:
FreeBSD/32 6.3 (duty) in debug mode
FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode
Linux/32 2.6 (jam) w/PGI compilers, w/default API=1.8.x,
w/C++ & FORTRAN, w/threadsafe, in debug mode
Linux/64-amd64 2.6 (amani) w/Intel compilers, w/default API=1.6.x,

w/szip filter, in production mode

exactly contains the selection, ie. if a 2-D element selection is currently

defined with the following points: (4,5), (6,8) (10,7), the bounding box
|

with be (4, 5), (10, 8). Calling this function on a "none" selection

returns fail.
