[svn-r24202] Bug fix: HDFFV-8271 Big.c error in address generated by random number.
Description: There is a bug in the current big.c tests. In a nut-shell, the writing part randomly picks 50 locations and write 4KB from that location. Random location range is from byte 0 to end of dataset. There is the problem--if the random location is greater than (end of dataset - 4KB), then error. Solution: Adjust the random number to be at least 4KB less than the end of the dataset. That allows it write 4KB more from the generated starting position. Tested: h5comittest plus jam serial build and test.
