spice/qxl: zap spice 0.4 migration compatibility bits

Live migration from and to spice 0.4 qxl devices isn't going to work.
Rip out the bits which attempt to support that.  Zap the subsection
logic which is obsolete now.  Bumb the version to make a clean cut.
This should obviously go in before 0.14 is released.
