Split patent grant clause out of LICENSE file
and update text to be more like that used by WebM.
These changes should make Go more acceptable
to the Fedora project and they are acceptable to the FSF.

Note:
* Exp2 doesn't have a special case for very small arguments
* Exp2 hasn't been subject to a proper error analysis

Also:
* add tests for Exp2 with integer argument
* always test Go versions of Exp and Exp2

	fmt.Printf("%U", 1) yields "U+0001"
It's essentially "U+%.4x" but lets you override the precision works in scan, too.

- use math.Sqrt instead of Math.sqrt
- use float64 for Point fields to match math.Sqrt
- distinguish between Point and Point3D for clarity
- add alignment sizes for complex types

Doing the tail recursion elimination explicitly
seems safer than leaving it to the compiler;
the code is still clean and easy to understand.

Before one could say
	{field}
or
	{field|formatter}
Now one can also say
	{field1 field2 field3}
or
	{field1 field2 field3|formatter}
and the fields are passed as successive arguments to the formatter,
analogous to fmt.Print.

Also ran "gofmt -s" and made use of copy([]byte, string) in the fasta benchmark.
