target-i386: X86CPU model subclasses
Register separate QOM types for each x86 CPU model.
This will allow management code to more easily probe what each CPU model
provides, by simply creating objects using the appropriate class name,
without having to restart QEMU.
This also allows us to eliminate the qdev_prop_set_globals_for_type()
hack to set CPU-model-specific global properties.
Instead of creating separate class_init functions for each class, I just
used class_data to store a pointer to the X86CPUDefinition struct for
each CPU model. This should make the patch shorter and easier to review.
Later we can gradually convert each X86CPUDefinition field to lists of
per-class property defaults.
The "host" CPU model is special, as the feature flags depend on KVM
being initialized. So it has its own class_init and instance_init
function, and feature flags are set on instance_init instead of
class_init.

aio: add aio_context_acquire() and aio_context_release()
It can be useful to run an AioContext from a thread which normally does

implemented by acquiring the AioContext and looping aio_poll() until all
requests have been completed.
The following pattern should work:
/* Event loop thread */
while (running) {
aio_context_acquire(ctx);
aio_poll(ctx, true);
aio_context_release(ctx);
}
/* Another thread */
aio_context_acquire(ctx);

acquiring and releasing - it is only needed when multiple threads will
call aio_poll() on the same AioContext.

Fairness means each locker gets a turn and the scheduler cannot cause

Recursive locking is useful for composition, it allows a sequence of

them.
This patch adds RFifoLock, a recursive lock that guarantees FIFO order.
Its first user is added in the next patch.
RFifoLock has one additional feature: it can be initialized with an
optional contention callback. The callback is invoked whenever a thread
must wait for the lock. For example, it can be used to poke the current
owner so that they release the lock soon.
