Instead of assuming that we can use irqfds if and only if
kvm_irqchip_in_kernel(), add a bool to the KVMState which
indicates this, and is set only on x86 and only if the
irqchip is in the kernel.
The kernel documentation implies that the only thing
you need to use KVM_IRQFD is that KVM_CAP_IRQFD is
advertised, but this seems to be untrue. In particular
the kernel does not (alas) return a sensible error if you
try to set up an irqfd when you haven't created an irqchip.
If it did we could remove all this nonsense and let the
kernel return the error code.

kvm_allows_irq0_override() is a totally x86 specific concept:
move it to the target-specific source file where it belongs.
This means we need a new header file for the prototype:
kvm_i386.h, in line with the existing kvm_ppc.h.
While we are moving it, fix the return type to be 'bool' rather
than 'int'.

Moving reset callback into cpu object from board level and
resetting cpu at the end of x86_cpu_realize() will allow properly
create cpu object during run-time (hotplug) without calling reset externaly.
When reset over QOM hierarchy is implemented, reset callback
should be removed.
v2:
- leave cpu_reset in pc_new_cpu() for now, it's to be cleaned up when APIC
init is moved in cpu.c

MP initialization protocol differs between cpu families, and for P6 and
onward models it is up to CPU to decide if it will be BSP using this
protocol, so try to model this. However there is no point in implementing
MP initialization protocol in qemu. Thus first CPU is always marked as BSP.
This patch:
- moves decision to designate BSP from board into cpu, making cpu
self-sufficient in this regard. Later it will allow to cleanup hw/pc.c
and remove cpu_reset and wrappers from there.
- stores flag that CPU is BSP in IA32_APIC_BASE to model behavior
described in Inted SDM vol 3a part 1 chapter 8.4.1
- uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP
patch is based on Jan Kiszka's proposal:

According to the Intel manual
"Intel® 64 and IA-32 Architectures Software Developer’s Manual
Volume 3", "3.4.4 Segment Loading Instructions in IA-32e Mode":
"When in compatibility mode, FS and GS overrides operate as defined by
32-bit mode behavior regardless of the value loaded into the upper 32
linear-address bits of the hidden descriptor register base field.
Compatibility mode ignores the upper 32 bits when calculating an effective address."
However, the code misses the 64-bit mode case, where an instruction with
address and segment size override would be translated incorrectly. For example,
inc dword ptr gs:260h[ebx*4] gets incorrectly translated to:
(uint32_t)(gs.base + ebx * 4 + 0x260)
instead of
gs.base + (uint32_t)(ebx * 4 + 0x260)

KVM performs TPR raising asynchronously to QEMU, specifically outside
QEMU's global lock. When an interrupt is injected into the APIC and TPR
is checked to decide if this can be delivered, a stale TPR value may be
used, causing spurious interrupts in the end.
Fix this by deferring apic_update_irq to the context of the target VCPU.
We introduce a new interrupt flag for this, CPU_INTERRUPT_POLL. When it
is set, the VCPU calls apic_poll_irq before checking for further pending
interrupts. To avoid special-casing KVM, we also implement this logic
for TCG mode.

The X86_64_DEF macro is a confusing way of making some terms
in a conditional only appear if TARGET_X86_64 is defined. We
only use it in two places, and in both cases this is for making
the same test, so abstract that check out into a function
where we can use a more conventional #ifdef.

Commit 11f8cdb removed all the uses of the X86_64_ONLY
macro. The BUGGY_64() macro has been unused for a long time:
it originally marked some ops which couldn't be enabled
because of issues with the pre-TCG code generation scheme.
Remove the now-unnecessary definitions of both macros.

commit c4baa0503d9623f1ce891f525ccd140c598bc29a improved SSE table
type safety which now raises compiler errors when latest QEMU was
configured with --enable-debug.
Fix this by splitting the SSE tables even further to separate
helper functions with different signatures.
Instead of crashing by calling address 0, the code now jumps to
label illegal_op.

QEMU exposes its version to the guest's hardware and in some cases that is wrong
(e.g. Windows prints messages about driver updates when you switch
the QEMU version).
There is a new field now on the struct QEmuMachine, hw_version, which may
contain the version that the specific machine should report. If that field is
set, then that machine will report that version to the guest.
