libqos: define SPAPR libqos functions

Define spapr_alloc_init()/spapr_alloc_init_flags()/spapr_alloc_uninit()

  to allocate and use SPAPR guest memory

Define qtest_spapr_vboot()/qtest_spapr_boot()/qtest_spapr_shutdown()

  to start SPAPR guest with QOSState initialized for it (memory management)

Move qtest_irq_intercept_in() from generic part to PC part.
