[Support] Make JSON handle doubles and int64s losslessly
Summary:
This patch adds a new "integer" ValueType, and renames Number -> Double.
This allows us to preserve the full precision of int64_t when parsing integers
from the wire, or constructing from an integer.
The API is unchanged, other than giving asInteger() a clearer contract.
In addition, always output doubles with enough precision that parsing will
reconstruct the same double.
