ENH: multi-process stream enhancements

This commit adds two main features to the
vtkMultiProcessStream object. First, it changes
the behavior of the Pop "array" methods. Now,
if the input array is not null, the code would expect
that the array is properly allocated, i.e., its size
should match the size of the data read and it would
just fill in the given buffer. Second, this commit adds
a method to get the size of the raw buffer that is returned
from calls to "GetRawData". The 1st byte of the raw buffer
is designated for the endianness, i.e., RawSize()=Size()+1.

ENH: Support for VtkIdType & enhancements

This method adds support for serializing/deserializing arrays
of vtkIdType. Further, it modifies the implementation such that
the array is popped from the bytestream directly in to the
pointer of the vtkDataArray instance as opposed to a temporary
buffer.

ENH: NearlyEqual fuzzy comparator and SafeDivision

Added a "NearlyEqual" fuzzy comparator based on Knuth,
"The Art of Computer Programming (vol II)" and safe division
that catches overflow/underflow.

ENH: Add vtkMPIUtilities -- parallel printf utils

Added vtkMPIUtilities which is intended to be used as
a centralized container to implement some common MPI
functions. Initially, vtkMPIUtilities provides support
for parallel printf
