Rename APIC helper functions to use an accel_* prefix instead of kvm_*
to support use by accelerators other than KVM. This is a preparatory
step for integrating MSHV support with common APIC logic.

This change seems to introduce a regression with interrupt remapping
when running a VM configured with an intel-iommu device and an assigned
PCI VF. At boot, Linux complains with :
Thank you for reporting, Cédric. From glancing over it, it looks like a
typo: we check for `ACCEL_KERNEL_GSI_IRQFD_POSSIBLE` instead of
`ACCEL_GSI_IRQFD_POSSIBLE` in ioapic.c. The former doesn't seem to be
defined anywhere.
Can you verify if changing that fixes the issue for you?
s/ACCEL_KERNEL_GSI_IRQFD_POSSIBLE/ACCEL_GSI_IRQFD_POSSIBLE/g
Oh I should have spotted that. Kernel does not hang anymore and messages
are gone. Sending a patch.
Thanks,
C.
