Check return values from g_poll and select
The current implementation of os_host_main_loop_wait() on Windows,
returns 1 only when a g_poll() event occurs because the return value of
select() is overridden. This is wrong as we may skip a socket event, as
shown in this example:
1. select() returns 0
2. g_poll() returns 1 (socket event occurs)
3. os_host_main_loop_wait() returns 1
4. qemu_iohandler_poll() sees no socket event because select() has
return before the event occurs
5. select() returns 1
6. g_poll() returns 0 (g_poll overrides select's return value)
7. os_host_main_loop_wait() returns 0
8. qemu_iohandler_poll() doesn't check for socket events because the
return value of os_host_main_loop_wait() is zero.
9. goto 5
This patch use one variable for each of these return values, so we don't
miss a select() event anymore.
Also move the call to select() after g_poll(), this will improve latency

vfio-pci: Make host MSI-X enable track guest
Guests typically enable MSI-X with all of the vectors in the MSI-X
vector table masked. Only when the vector is enabled does the vector
get unmasked, resulting in a vector_use callback. These two points,
enable and unmask, correspond to pci_enable_msix() and request_irq()
for Linux guests. Some drivers rely on VF/PF or PF/fw communication
channels that expect the physical state of the device to match the
guest visible state of the device. They don't appreciate lazily
enabling MSI-X on the physical device.
To solve this, enable MSI-X with a single vector when the MSI-X
capability is enabled and immediate disable the vector. This leaves
the physical device in exactly the same state between host and guest.
Furthermore, the brief gap where we enable vector 0, it fires into
userspace, not KVM, so the guest doesn't get spurious interrupts.
Ideally we could call VFIO_DEVICE_SET_IRQS with the right parameters
to enable MSI-X with zero vectors, but this will currently return an

usbredir: Add support for buffered bulk input (v2)
Buffered bulk mode is intended for bulk *input* endpoints, where the data is
of a streaming nature (not part of a command-response protocol). These
endpoints' input buffer may overflow if data is not read quickly enough.
So in buffered bulk mode the usb-host takes care of the submitting and
re-submitting of bulk transfers.
Buffered bulk mode is necessary for reliable operation with the bulk in
endpoints of usb to serial convertors. Unfortunatelty buffered bulk input
mode will only work with certain devices, therefor this patch also adds a
usb-id table to enable it for devices which need it, while leaving the
bulk ep handling for other devices unmodified.
Note that the bumping of the required usbredir from 0.5.3 to 0.6 does
not mean that we will now need a newer usbredir release then qemu-1.3,
.pc files reporting 0.5.3 have only ever existed in usbredir builds directly
from git, so qemu-1.3 needs the 0.6 release too.
Changes in v2:
-Split of quirk handling into quirks.c

target-ppc: Slim conversion of model definitions to QOM subclasses
Since the model list is highly macrofied, keep ppc_def_t for now and
save a pointer to it in PowerPCCPUClass. This results in a flat list of
subclasses including aliases, to be refined later.
Move cpu_ppc_init() to translate_init.c and drop helper.c.
Long-term the idea is to turn translate_init.c into a standalone cpu.c.
Inline cpu_ppc_usable() into type registration.
Split cpu_ppc_register() in two by code movement into the initfn and
by turning the remaining part into a realizefn.
Move qemu_init_vcpu() call into the new realizefn and adapt
create_ppc_opcodes() to return an Error.
Turn -cpu host into its own subclass. This requires to move the
kvm_enabled() check in ppc_cpu_class_by_name() to avoid the class being
found via the normal name lookup in the !kvm_enabled() case.
Turn kvmppc_host_cpu_def() into the class_init and add an initfn that
asserts KVM is in fact enabled.
Implement -cpu ? and the QMP equivalent in terms of subclasses.
This newly exposes -cpu host to the user, ordered last for -cpu ?.

PPC: KVM: set has-idle in guest device tree
On e500mc, the platform doesn't provide a way for the CPU to go idle.
To still not uselessly burn CPU time, expose an idle hypercall to the guest
if kvm supports it.
