7508f98c71 optimize internal parsing function -- avoid unsafe []byte parsing 
Making xtob take two byte arguments avoids a lot of slicing.  This makes
the Parse function faster.  In addition, because so much slicing is
avoiding, duplicating the parse logic to ParseBytes resulted in the
function being faster than Parse (<1ns).

The BenchmarkParseBytesNative function has been removed (parseBytes was
identical to ParseBytes).  And a new benchmark,
BenchmarkParseBytesUnsafe, has been added to benchmark the old way of
parsing []byte (which is slightly slower than Parse and thus the new
ParseBytes implementation).
