[Standards] Jingle File Transfer (XEP-0234) uses NonNegativeInteger instead of UnsignedLong.

This is a very minor issue, but XEP-0234 uses positiveInteger as
attribute type for the FileTransferElementType's size attribute.

positiveInteger contains all positive numbers except '0', which requires
implementers to choose eg. the BigInteger class to represent that value.

I think unsignedLong would fit better here. Same goes for the
fileTransferRangeType's offset value, which is currently
nonNegativeInteger. This limits the size of the transferred file to 4GB
or less.

Last but not least, the fileTransferRangeType is missing the length
