[svn-r9267] Purpose:

Added H5Pget_data_transform
Added support for polynomial data transforms

Description:
There is now support for polynomial data transforms (ie, (2+x)*(x-5)) instead
of just linear ones.

Note that, in order to compute a polynomial transform, one temporary copy of
the original data must be stored for each occurence of "x" in the transform
expression.  This can result in very high memory usage for expressions of high
order.

Platforms tested:
sol + eirene
