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.
PR kern/57304

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)
simpler.

Added flags to store status of attaching a virtio device

This prevents a panic on reboot after a virtio device had called
virtio_child_attach_failed().

Fix wrong variable names
This fixes build errors in virtio_mmio.c

virtio: use the new syntax for snprintb(3) format strings.

The old syntax is limited to 32 bits only (and has 1-based bit numbers
which is rather incovenient too).

Add VirtIO PCI v1.0 attachments and fix the drivers affected.

The vioif, ld, scsi, viornd and viomb devices were adjusted when needed and
tested both in legacy 0.9 and v1.0 attachments trough PCI on amd64, sparc64,
aarch64 and aarch64-eb. ACPI/FDT attachments also tested on
aarch64/aarch64-eb.

Known issues

* viomb on aarch64 works only with ACPI/FDT attachment but not with PCI
  attachment. PCI and ACPI/FDT attachment works on aarch64-eb.

* virtio on sparc64 attaches but is it not functioning though not a
  regression.

While ld(4) is MP safe, many backends are not.
Add a flag for backends that are MP safe. Take KERNEL_LOCK when calling
into a backend that doesn't have the flag set. Do the same for the
discard routine.
Fixes PR 52462.
Defer sdmmc discard operations to the sdmmc task queue. Fixes a panic
introduced by ld.c r1.102.
validate length for discard operation and split operation when byte length
doesn't fit into 'int'.
make the sc_discard interface for the ld backend asynchronous and
signal completion through new callback lddiscardend. Use a standard
struct buf to pass disk address and range instead of two off_t values.
make lddiscard synchronous again. This is a requirement of the current
ffs discard code.
Initialize error also in the case where len=0, which just succeeds.
while here, assert that the len is indeed non-negative. this is already
confirmed by sys_fdiscard, but let's be sure.

merge to -current.

Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
   to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
   source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
   avoid expensive operations on disabled entropy sources; make the
   rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
   have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
   system events, and skew between clocks, with a sample implementation
   for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files).  Tested with release
builds on amd64 and evbarm and live testing on amd64.

According to "Virtio PCI Card Specification v0.9.2 DRAFT" there is no
feature named VIRTIO_BLK_F_SECTOR_MAX so remove it.  Linux seems to use
this feature bit as VIRTIO_BLK_F_TOPOLOGY.

Use VIRTIO_BLK_F_BLK_SIZE * VIRTIO_BLK_F_SEG_MAX as the drivers maxxfer
and reorder so sc_secsize gets set before use.

As maxxfer may not be a multiple of page size add one more segment to
the dma maps.

Tested on Linux 3.1.1 host by Guillaume Lasmayous.

Import of the virtio driver written by MINOURA Makoto <minoura@netbsd.org>
with minor changes to make it compile an run on -current.  This driver
speeds up disk and network access in virtual environments like KVM.

Enabled on i386 and amd64.  Tested with a CentOS 5.7 x86_64 host.

See http://ozlabs.org/~rusty/virtio-spec/virtio.pdf for the specification.
