Summary

This adds virtio modern support handling to bhyve.
pci_emul_add_capability is exposed to support PCIY_VENDOR-type
virtio modern capabilities.

Current virtio devices are slightly changed to adopt
vi_pci_cfgread/vi_pci_cfg_write.

Virtio modern is not exposed to device emulation code currently.
