Add a new base CPU model called Opteron_G5 to model the latest
Opteron CPUs. This increases the model value and model numbers and
adds TBM, F16C and FMA over the latest G4 model.

Update QEMU's knowledge of CPUID bit names. This allows to
enable/disable those new features on QEMU's command line when
using KVM and prepares future feature enablement in QEMU.
This adds F16C, RDRAND, LWP, TBM, TopoExt, PerfCtr_Core, PerfCtr_NB,
FSGSBASE, BMI1, AVX2, BMI2, ERMS, PCID, InvPCID, RTM, RDSeed and ADX.

Developer Manual, and the Linux kernel for the leaf 7 bits.

Header file dependency is a frickin' nightmare right now. cpu.h tends
to get included in our 'include everything' header files but qdev also
needs to include those headers mainly for qdev-properties since it knows
about CharDriverState and friends.
We can solve this for now by splitting out qdev.h along the same lines
that we previously split the C file. Then cpu.h just needs to include
qdev-core.h.
hw/qdev.h is split into following new headers:
hw/qdev-core.h
hw/qdev-properties.h
hw/qdev-monitor.h

Every time we make a tiny change on a header file, we often find
circular header dependency problems. To avoid this nightmare, we need to
stop including qemu-common.h from other headers, and we should gradually
move the declarations from the catch-all qemu-common.h header to their
specific headers.
This simply adds a comment documenting the rules about qemu-common.h,
hoping that people will see it before including qemu-common.h from other
header files, and before adding more declarations to qemu-common.h.

This makes use of the new level irqfd support enabling bypass of qemu
userspace both on INTx injection and unmask. This significantly
boosts the performance of devices making use of legacy interrupts (ex.
~60% better netperf TCP_RR scores for an e1000e assigned to a Linux
guest and booted with pci=nomsi). This also avoids flipping mmaps on
and off to simulate EOIs, so greatly improves performance of device
access in addition to interrupt latency.

Commit ed2aec4867f0d5f5de496bb765347b5d0cfe113d changed the return
value of aio_ctx_prepare from false to true when only idle bottom
halves are available. This broke PC old-style DMA, which uses them.
Fix this by making aio_ctx_prepare return true only when non-idle
bottom halves are scheduled to run.

Define a new global dma_context_memory which is a DMAContext corresponding
to the global address_space_memory AddressSpace. This can be used by
sysbus peripherals like sysbus-ohci which need to do DMA.
In particular, use it in the sysbus-ohci device, which fixes a
segfault when attempting to use that device.

The inquiry command, for the case of VPD=1, was returning short
responses; the number of returned bytes was just the number of bytes
in the request, without padding to the specified allocation length
with zero bytes. This is usually harmless, but it is a violation
of the SCSI specification.
To fix this, always pad with zero bytes to r->cmd.xfer in
scsi_disk_emulate_command, and return at most r->buflen bytes
(the size of the buffer for command data) rather than at most
buflen bytes (the number of bytes that was filled in).
Before this patch, "strace sg_inq -p0x83 /dev/sda" would report a
non-zero resid value. After this patch, it reports resid=0.
