PIIX3: reset the VM when the Reset Control Register's RCPU bit gets set
Traditional PCI config space access is achieved by writing a 32 bit
value to io port 0xcf8 to identify the bus, device, function and config
register. Port 0xcfc then contains the register in question. But if you
write the appropriate pair of magic values to 0xcf9, the machine will
reboot. Spectacular! And not standardised in any way (certainly not part
of the PCI spec), so different chipsets may have different requirements.
Booo.
In the PIIX3 spec, IO port 0xcf9 is specified as the Reset Control
Register. Bit 1 (System Reset, SRST) would normally differentiate between
soft reset and hard reset, but we ignore the difference beyond allowing
the guest to read it back.
RHBZ reference: 890459
This patch introduces the following overlap between the preexistent
"pci-conf-idx" region and the "piix3-reset-control" region just being
added. Partial output from "info mtree":
I sanity-checked the patch by booting a RHEL-6.3 guest and found no
problems. I summoned gdb and set a breakpoint on rcr_write() in order to
gather a bit more confidence. Relevant frames of the stack:
The "ioport_write_table" and "ioport_opaque" arrays describe the flattened
IO port space. The first array is less interesting (it selects a thunk
function). The "ioport_opaque" array is interesting because it decides how
writing to the port is implemented ultimately.
The higher priority of "piix3-reset-control" ensures that the 0xcf9
entries in ioport_write_table / ioport_opaque will always belong to it,
independently of its relative registration order versus "pci-conf-idx".

virtio-net: introduce a new macaddr control
In virtio-net guest driver, currently we write MAC address to
pci config space byte by byte, this means that we have an
intermediate step where mac is wrong. This patch introduced
a new control command to set MAC address, it's atomic.
VIRTIO_NET_F_CTRL_MAC_ADDR is a new feature bit for compatibility.
"mac" field will be set to read-only when VIRTIO_NET_F_CTRL_MAC_ADDR
is acked.

Once guest overrides virtio net primary mac,
it retains the value set until qemu exit.
This is inconsistent with standard nic behaviour.
To fix, revert the mac to the original value on reset.

This addresses two issues with config generation
1. rule generating timestamp has side effect.
Thus cleanup on error does not work.
2. rule for handling timestamp is too generic.
It can create any missing .h file.
As a result when .h file is removed, build
might try to create it using this rule which
results in build errors.

Add code comment to clarify the reason we set ICS with ICR:
the reason was previously undocumented and git
log confused rather than clarified the comments.
