[svn-r13459] Fix for Bug #763 - failure to create dataset of variable-length data with fill value. In function

Browse Source 
H5O_fill_convert, the background buffer was allocated without clearing.  Later in H5T_vlen_disk_write
, library thought there's data in this background buffer.  Changed the allocating function to 
CALLOC.
