Quincey Koziol f82774c0d5 [svn-r19092] Description: 
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/C++ & FORTRAN, in production mode
        Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN,
                w/szip filter, in production mode
        Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
                in production mode
        Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in debug mode

/*
This program will test irregular hyperslab selections with collective write and read.
The way to test whether collective write and read works is to use independent IO
output to verify the collective output.
1) We will write two datasets with the same hyperslab selection settings;
one in independent mode,
one in collective mode,
2) We will read two datasets with the same hyperslab selection settings,
1. independent read to read independent output,
independent read to read collecive output,
Compare the result,
If the result is the same, then collective write succeeds.
2. collective read to read independent output,
independent read to read independent output,
Compare the result,
If the result is the same, then collective read succeeds.

/****************************************************************
**
** lower_dim_size_comp_test__verify_data():
**
** Examine the supplied buffer to see if it contains the
** expected data. Return TRUE if it does, and FALSE
** otherwise.
**
** The supplied buffer is presumed to this process's slice
** of the target data set. Each such slice will be an
** n-cube of rank (rank -1) and the supplied edge_size with
** origin (mpi_rank, 0, ... , 0) in the target data set.
**
** Further, the buffer is presumed to be the result of reading
** or writing a checker board selection of an m (1 <= m <
** rank) dimensional slice through this processes slice
** of the target data set. Also, this slice must be parallel
** to the fastest changing indicies.
**
** It is further presumed that the buffer was zeroed before
** the read/write, and that the full target data set (i.e.
** the buffer/data set for all processes) was initialized
** with the natural numbers listed in order from the origin
** along the fastest changing axis.
**
** Thus for a 20x10x10 dataset, the value stored in location
** (x, y, z) (assuming that z is the fastest changing index
** and x the slowest) is assumed to be:
**
** (10 * 10 * x) + (10 * y) + z
**
** Further, supposing that this is process 10, this process's
** slice of the dataset would be a 10 x 10 2-cube with origin
** (10, 0, 0) in the data set, and would be initialize (prior
** to the checkerboard selection) as follows:
**
** 1000, 1001, 1002, ... 1008, 1009
** 1010, 1011, 1012, ... 1018, 1019
** . . . . .
** . . . . .
** . . . . .
** 1090, 1091, 1092, ... 1098, 1099
**
** In the case of a read from the processors slice of another
** data set of different rank, the values expected will have
** to be adjusted accordingly. This is done via the
** first_expected_val parameter.
**
** Finally, the function presumes that the first element
** of the buffer resides either at the origin of either
** a selected or an unselected checker. (Translation:
** if partial checkers appear in the buffer, they will
** intersect the edges of the n-cube oposite the origin.)

*
* 1) Reads or writes exactly one chunk,
*
* 2) Has no in memory buffer for any other chunk.

* The test differers from Rob Latham's bug report in
* that is runs with an arbitrary number of proceeses,
* and uses a 1 dimensional dataset.
