 Set virtqueues in virtio_child_attach_finish
 The number of virtqueue maybe change in a part of VirtIO devices
 (e.g. vioif(4)). And it is fixed after negotiation of features.
 So the configuration is moved into the function.
 viocon(4): fix not to allocate unused virtqueue
 viocon(4) allocates 4 virtqueues but it only uses 2 (0 and 1) queues.
 Added functions to set interrupt handler and index into virtqueue
 Added check of pointer for allocated memory before release of resource
 Setup virtqueues after registering them to virtio_softc
 restore fetch of qsize.
 Mark as MPSAFE.
 virtio(4): Avoid name collision with global intrhand on sparc64.
 Pacifies -Werror=shadow.
 No functional change intended.
 Use PRIuBUSSIZE to print bus_size_t variables.
 virtio(4): Fix sizing of virtqueue allocation.
 vq->vq_avail[0].ring is a zero-length array, and thus sizeof is zero;
 likewise vq->vq_used[0].ring.
 Use vq->vq_avail[0].ring[0] and vq->vq_used[0].ring[0] to fix this
 and restore the previous allocation sizing logic.
 XXX We shouldn't use zero-length arrays here -- they are asking for
 trouble like this, and C99 has a standard way to express what we're
 actually trying to get at it, flexible array members.

 virtio(4): Use flexible array members, not zero-length arrays.
 This enables the compiler to detect sizeof mistakes like
 PR kern/57304.
 Use descriptor chain for free slots instead of vq_entry list
 Descriptors can be chained by themself. And descriptors added to
 avail ring or used ring are already chained. But it was not used
 for unused descriptors and another linked list structure named
 vq_entry was used.
 The chain is also used for unused descriptors to make virtio(4)
 Added flags to store status of attaching a virtio device
 This prevents a panic on reboot after a virtio device had called
 Fix wrong variable names
 This fixes build errors in virtio_mmio.c
