        Change stream position.

        Change the stream position to byte offset offset. Argument offset is
        interpreted relative to the position indicated by whence.  Values
        for whence are ints:

        * 0 -- start of stream (the default); offset should be zero or positive
        * 1 -- current stream position; offset may be negative
        * 2 -- end of stream; offset is usually negative
        Some operating systems / file systems could provide additional values.

        Return an int indicating the new absolute position.
