virtio-blk: Turn drive serial into a qdev property

It needs to be a qdev property, because it belongs to the drive's
guest part. Precedence: commit a0fef654 and 6ced55a5.

Bonus: info qtree now shows the serial number.

s390x: keep hint on virtio managing size

The s390x virtio bus keeps management information on virtio after the top
of the guest's RAM. We need to be able to tell the guest the size of its
RAM (without virtio stuff), but also be able to trap when the guest accesses...

s390x: fix s390-virtio-serial

Commit 6b331efb733a0f913ddc0b7762a1307dec304061 broke the s390 proxy version
of virtio-serial by only taking its PCI brother into account.

So let's adjust s390-virtio-serial the same way as its PCI counterpart, making
it compile and work again....

Delete useless 'extern' qualifiers for functions

'extern' qualifier is useless for function declarations. Delete
them.

s390: compile fixes

The s390 target doesn't compile out of the box anymore. This patch fixes all
the obvious glitches that got introduced in the last few weeks.

virtio-net: Make tx_timer timeout configurable

Add an option to make the TX mitigation timer adjustable as a device
option. The 150us hard coded default used currently is reasonable,
but may not be suitable for all workloads, this gives us a way to
adjust it using a single binary. We can't support any random option...

Implement virtio reset

The guest may issue a RESET command for virtio. So far we didn't bother
to implement it, but with my new bootloader we actually need it for Linux
to get back to a safe state.

block: add topology qdev properties

Add three new qdev properties to export block topology information to
the guest. This is needed to get optimal I/O alignment for RAID arrays
or SSDs.

The options are:

- physical_block_size to specify the physical block size of the device,...

virtio-console: qdev conversion, new virtio-serial-bus

This commit converts the virtio-console device to create a new
virtio-serial bus that can host console and generic serial ports. The
file hosting this code is now called virtio-serial-bus.c.

The virtio console is now a very simple qdev device that sits on the...

virtio: add features as qdev properties

Add feature bits as properties to virtio. This makes it possible to e.g. define
machine without indirect buffer support, which is required for 0.10
compatibility, or without hardware checksum support, which is required for 0.11...

Add S390x virtio machine bus

On S390x we don't want to go through the hassle of emulating real existing
hardware, because we don't need to for running Linux.

So let's instead implement a machine that is 100% based on VirtIO which we
fortunately implement already....
