machine: Refactor smp_parse() in vl.c as MachineClass::smp_parse()

To make smp_parse() more flexible and expansive, a smp_parse function
pointer is added to MachineClass that machine types could override.

The generic smp_parse() code in vl.c is moved to hw/core/machine.c, and
become the default implementation of MachineClass::smp_parse. A PC-specific
function called pc_smp_parse() has been added to hw/i386/pc.c, which in
this patch changes nothing against the default one .

hw: Nuke hw_compat_4_0_1 and pc_compat_4_0_1

Commit c87759ce876a fixed a regression affecting pc-q35 machines by
introducing a new pc-q35-4.0.1 machine version to be used instead
of pc-q35-4.0. The only purpose was to revert the default behaviour
of not using split irqchip, but the change also introduced the usual
hw_compat and pc_compat bits, and wired them for pc-q35 only.

This raises questions when it comes to add new compat properties for
4.0* machine versions of any architecture. Where to add them ? In
4.0, 4.0.1 or both ? Error prone. Another possibility would be to teach
all other architectures about 4.0.1. This solution isn't satisfying,
especially since this is a pc-q35 specific issue.

It turns out that the split irqchip default is handled in the machine
option function and doesn't involve compat lists at all.

Drop all the 4.0.1 compat lists and use the 4.0 ones instead in the 4.0.1
machine option function.

Move the compat props that were added to the 4.0.1 since c87759ce876a to
4.0.

Even if only hw_compat_4_0_1 had an impact on other architectures,
drop pc_compat_4_0_1 as well for consistency.

q35: Revert to kernel irqchip

Commit b2fc91db8447 ("q35: set split kernel irqchip as default") changed
the default for the pc-q35-4.0 machine type to use split irqchip, which
turned out to have disasterous effects on vfio-pci INTx support. KVM
resampling irqfds are registered for handling these interrupts, but
these are non-functional in split irqchip mode. We can't simply test
for split irqchip in QEMU as userspace handling of this interrupt is a
significant performance regression versus KVM handling (GeForce GPUs
assigned to Windows VMs are non-functional without forcing MSI mode or
re-enabling kernel irqchip).

The resolution is to revert the change in default irqchip mode in the
pc-q35-4.1 machine and create a pc-q35-4.0.1 machine for the 4.0-stable
branch. The qemu-q35-4.0 machine type should not be used in vfio-pci
configurations for devices requiring legacy INTx support without
explicitly modifying the VM configuration to use kernel irqchip.

hw: report invalid disable-legacy|modern usage for virtio-1-only devs

A number of virtio devices (gpu, crypto, mouse, keyboard, tablet) only
support the virtio-1 (aka modern) mode. Currently if the user launches
QEMU, setting those devices to enable legacy mode, QEMU will silently
create them in modern mode, ignoring the user's (mistaken) request.

This patch introduces proper data validation so that an attempt to
configure a virtio-1-only devices in legacy mode gets reported as an
error to the user.

Checking this required introduction of a new field to explicitly track
what operating model is to be used for a device, separately from the
disable_modern and disable_legacy fields that record the user's
requested configuration.

machine: Move nvdimms state into struct MachineState

As NVDIMM support is looming for ARM and SPAPR, let's
move the acpi_nvdimm_state to the generic machine struct
instead of duplicating the same code in several machines.
It is also renamed into nvdimms_state and becomes a pointer.

nvdimm and nvdimm-persistence become generic machine options.
They become guarded by a nvdimm_supported machine class member.
We also add a description for those options.

virtio-blk: add "discard" and "write-zeroes" properties

In order to avoid migration issues, we enable DISCARD and
WRITE_ZEROES features only for machine type >= 4.0

As discussed with Michael S. Tsirkin and Stefan Hajnoczi on the
list [1], DISCARD operation should not have security implications
(eg. page cache attacks), so we can enable it by default.

usb: assign unique serial numbers to hid devices

Windows guests have trouble dealing with usb devices having identical
serial numbers. So, assign unique serial numbers to usb hid devices.
All other usb devices have this already.

In the past the fixed serial number has been used to indicate working
remote setup to linux guests. Here is a bit of history:

* First there was nothing.
* Then I added a rule to udev checking for serial == 42.
(this is in rhel-6).
* Then systemd + udev merged.
* Then I changed the rule to check for serial != 1 instead, so we can
use any serial but "1" which is the one the old broken devices had
(this is in rhel-7). March 2014 in upstream systemd.
* Then all usb power management rules where dropped from systemd (June
2015). Which I figured today (Sept 2018), after wondering that the
rules are gone in fedora 28.

So, three years ago the serial number check was dropped upstream, yet I
hav't seen a single report about autosuspend issues (or cpu usage for
usb emulation going up, which is the typical symtom).

So I figured I can stop worring that changing the serial number will
break things and just do it.

And even if it turns out autosuspend is still an issue: I think
meanwhile we can really stop worrying about guests running in old qemu
versions with broken usb suspend (fixed in 0.13 !). If needed we can
enable autosuspend unconditionally in guests.
