[svn-r5463] Description:
Folded the changes made in v1.4 into v1.5. print library version information in help page too. Specify the nofill feature supported in v1.5 only. Print the values of the KB, MB and GB in case a user wants to see them. Setup a macro, H5_HAVE_NOFILL, to indicate if Dataset no fill feature is supported. If not, --no-fill is an invalid option. Platforms tested: modi4
