gio: Bump copy buffer size to 256k by default

Browse Source 
This is small enough that it shouldn't cause problems on most machines
we support, but big enough to increase throughput on a lot of devices
and network protocols.

Note that the actual value is 256k minus malloc overhead, so that it
fits nicely in a 256k block (as suggested by Alexander Larsson).
