virtio: Add support for guest setting of queue size

The MMIO virtio transport spec allows the guest to tell the host how
large the queue size is. Add virtio_queue_set_num() function which
implements this in the QEMU common virtio support code.

virtio-net: add feature bit for any header s/g

Old qemu versions required that 1st s/g entry is the header.

Since QEMU 1.5, patchset titled "virtio-net: iovec handling cleanup"
removed this limitation but a feature bit is needed so guests know it's
safe to lay out header differently....

PPC: dbdma: Move processing to io

Soon we will introduce intermediate processing pauses which will
allow the bottom half to restart a DMA request that couldn't be
fulfilled yet.

For that to work, move the processing variable into the io struct
which is what DMA providers work with....

PPC: dbdma: Support unaligned DMA access

The DBDMA engine really just reads bytes from a producing device (IDE
in our case) and shoves these bytes into memory. It doesn't care whether
any alignment takes place or not.

Our code today however assumes that block accesses always happen on...

PPC: dbdma: Move defines into header file

We usually keep struct and constant definitions in header files. Move
them there to stay consistent and to make access to fields easier.

PPC: dbdma: Introduce kick function

The DBDMA engine really is running all the time, waiting for input. However
we don't want to waste cycles constantly polling.

So introduce a kick function that data providers can call to notify the
DBDMA controller of new input....

PPC: dbdma: Move static bh variable to device struct

The DBDMA controller has a bottom half to asynchronously process DMA
request queues.

This bh was stored as a gross static variable. Move it into the device
struct instead.

While at it, move all users of it to the new generic kick function....
