Codereview request: 7109837 Provide a mechanism for computing an Adler32 checksum for the contents of a ByteBuffer

[Xueming Shen]

Alan, Ulf,

Webrev has been updated accordingly

(1) {@code}
(2) better wording for opening sentence as suggested
(3) added -benhmark option for TimeCheckSum, so only do the benchmark run
      (with 100000 iteration) when  this option is manually specified. 
Without the
      option, it runs as a "normal"  regression test with iteration 1.
(4) to use "ratio" of "time of ByteBuffer: time of byte[]" as

Thanks,
Sherman
