[svn-r6584] 
Purpose: Maintenance

Description:  There was an old h5import (h5import.c) tool in the misc directory.
              The tool created 8-bit integer datasets , it was never tested and/or
              supported.
Solution:     We decided to rename old h5import.c to h5createU8.c. The new name reflects what
              actually old tool does. New executable h5createU8 is built in the misc directory.
              h5import.c file (old one) is still in the misc directory, but h5import executable
              is not built. (Sorry if I confused you!)

Platforms tested: vebena, arabica, modi4 were tested
