kvm: Implement kvm_irqchip_in_kernel like kvm_enabled

To both avoid that kvm_irqchip_in_kernel always has to be paired with
kvm_enabled and that the former ends up in a function call, implement it
like the latter. This means keeping the state in a global variable and...

kvm: x86: Establish IRQ0 override control

KVM is forced to disable the IRQ0 override when we run with in-kernel
irqchip but without IRQ routing support of the kernel. Set the fwcfg
value correspondingly. This aligns us with qemu-kvm.

kvm: Clean up stubs

No one references kvm_check_extension, kvm_has_vcpu_events, and
kvm_has_robust_singlestep outside KVM code.

kvm_update_guest_debug is never called, thus has no job besides
returning an error.

Introduce log_start/log_stop in CPUPhysMemoryClient

In order to use log_start/log_stop with Xen as well in the vga code,
this two operations have been put in CPUPhysMemoryClient.

The two new functions cpu_physical_log_start,cpu_physical_log_stop are
used in hw/vga.c and replace the kvm_log_start/stop. With this, vga does...

from cpus.c. This patch also fixes --disable-kvm build by providing the
missing kvm_on_sigbus_vcpu kvm-stub.

kvm: test for ioeventfd support on old kernels

There used to be a limit of 6 KVM io bus devices in the kernel.
On such a kernel, we can't use many ioeventfds for host notification
since the limit is reached too easily.

Add an API to test for this condition....

provide a stub version of kvm-all.c if !CONFIG_KVM

This allows limited use of kvm functions (which will return ENOSYS)
even in once-compiled modules. The patch also improves a bit the error
messages for KVM initialization.
