We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.

This changes the *_run_on_cpu APIs (and helpers) to pass data in a
run_on_cpu_data type instead of a plain void *. This is because we
sometimes want to pass a target address (target_ulong) and this fails on
32 bit hosts emulating 64 bit guests.

The MMIO based interface to APIC doesn't work well with MSIs that have
upper address bits set (remapped x2APIC MSIs). A specialized interface
is a quick and dirty way to avoid the shortcoming.

CPUState is a fairly common pointer to pass to these helpers. This means
if you need other arguments for the async_run_on_cpu case you end up
having to do a g_malloc to stuff additional data into the routine. For
the current users this isn't a massive deal but for MTTCG this gets
cumbersome when the only other parameter is often an address.
This adds the typedef run_on_cpu_func for helper functions which has an
explicit CPUState * passed as the first parameter. All the users of
run_on_cpu and async_run_on_cpu have had their helpers updated to use
CPUState where available.

The parsing of KVM_SET_LAPIC's input depends on the current value of the
APIC base MSR---which indeed is stored in APICCommonState---but for historical
reasons APIC base is set through KVM_SET_SREGS together with cr8 (which is
really just the APIC TPR) and the actual "special CPU registers".
APIC base must now be set before the actual LAPIC registers, so do that
in kvm_apic_put. It will be set again to the same value with KVM_SET_SREGS,
but that's not a big issue.
This only happens since Linux 4.8, which checks for x2apic mode in
KVM_SET_LAPIC. However it's really a QEMU bug; until the recent
commit 78d6a05 ("x86/lapic: Load LAPIC state at post_load", 2016-09-13)
QEMU was indeed setting APIC base (via KVM_SET_SREGS) before the other
LAPIC registers.

Load the LAPIC state during post_load (rather than when the CPU
starts).
This allows an interrupt to be delivered from the ioapic to
the lapic prior to cpu loading, in particular the RTC that starts
ticking as soon as we load it's state.
Fixes a case where Windows hangs after migration due to RTC interrupts
disappearing.

kvm-apic.io_memory memory region had its parent set to NULL at
memory_region_init_io() time, so it ended up as a child in
/unattached contaner.
As result when kvm-apic instance was deleted, the child property
/unattached/kvm-apic-msi[XXX] contained a reference to
kvm-apic.io_memory address which was freed as part of kvm-apic.
Do the same as 'apic' and make kvm-apic instance the owner
of the memory region so that it won't end up in /unattached
and gets cleanly released along with related kvm-apic instance.
