hdf5/tools/h4toh5anno.c
MuQun Yang a219b97a88 [svn-r2839] 
Purpose:
     check in beta release h4toh5 converter
Description:
     1. add copy right and other comments to all .h and .c files
     2. fix bugs on sds unlimited dimension, hdf5 dimensional scale attribute and vdata translating
         from h4 to h5.

Solution:
     2.
        1) for sds with unlimited dimension to be converted into extensible hdf5 dataset,
        on hdf5 side, has to set a default chunk size even though the corresponding hdf4 file is not
	chunked.
        2) in this version, if sds object doesn't have dimensional scale data, we will not show
           the default hdf4 dimensional name ("fakedim0", etc.) in the new hdf5 dimensional scale
	   name attribute.
        3) fix a bug transferring vdata of which the field includes a character array. Make it correctly transfer into the corresponding hdf5 compound data type.


Platforms tested:

      eirene,arabica,baldric,hawkwind,paz,gondolin on new set of hdf4 test files.
