Remove third party floating point library
We can depend on standard primitives for these operations in chrome os.
Note the formatting of DoubleToString() changes a little since the
standard primitives are a little less pretty.
The behavior of StringToDouble changed a little with respect to numbers
not representable as a double (too large or small). StringToDouble
still reports a broken conversion, but the value returned is infinity
rather than the maximum finite value.
