hdf5_der

[svn-r22127] Purpose: Fix earray failure

Description:
In H5Dearray.c, functions would "swizzle" the chunk offset and "down" number of
chunks in order to more the unlimited dimension to be the first dimension, but
they would not swizzle the chunk dimensions.  This could cause two chunks to
have the same index, causing problems.  Modified code to swizzle the chunk
dimensions, and added a test.

Note: There is still a problem with h5watch that appears to be unrelated.
