Plus:
- calibration "test" - include in tests with gotest -calibrate
- basic Mul benchmark
- extra multiplication tests
- various cleanups

This change improves multiplication speed of numbers >= 30 words
in length (current threshold; found empirically with calibrate):

The multiplication benchmark (multiplication of a variety of long numbers)
improves by ~35%, individual multiplies can be significantly faster.

There's no impact on pidigits for -n=10000 or -n=20000

This matches the old JSON package behavior.
All lowercase names are not as standard as I believed,
and it seems less surprising to need to write

	type T struct { Field string "field" }

to get lower case (behavior after this CL) than it does to need
to write

	type T struct { Field string "Field" }

to preserve the case (behavior before this CL).

Also test and  fix unmarshal into non-nil interface
value or pointer.
