Ross Lagerwall 5a6f13d16f gio: Prevent hang writing to a large GMemoryOutputStream ...

Fix a hang due to overflow by using unsigned numbers and explicitly
checking if the number overflows to zero.  This also fixes the previous
logic which assigned an int which may be negative to an unsigned number
resulting in sign extension and strange results.

Use gsize rather than int to allow for large streams on 64 bit machines.
