Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.
This commit was created with scripts/clean-includes, with the change
to target/s390x/gen-features.c manually reverted, and blank lines
around deletions collapsed.

System headers should be included with <...>, our own headers with
"...". Offenders tracked down with an ugly, brittle and probably
buggy Perl script. Previous iteration was commit a9c94277f0.
Delete inclusions of "string.h" and "strings.h" instead of fixing them
to <string.h> and <strings.h>, because we always include these via
osdep.h.
Put the cleaned up system header includes first.
While there, separate #include from file comment with exactly one
blank line.

[Register/unregister VCPU thread with RCU. - Paolo]
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Implements the Windows Hypervisor Platform accelerator (WHPX) target. Which
acts as a hypervisor accelerator for QEMU on the Windows platform. This enables
QEMU much greater speed over the emulated x86_64 path's that are taken on
Windows today.
1. Adds support for vPartition management.
2. Adds support for vCPU management.
3. Adds support for MMIO/PortIO.
4. Registers the WHPX ACCEL_CLASS.

In order to enable TCE operations support in KVM, we have to inform
the KVM about VFIO groups being attached to specific LIOBNs;
the necessary bits are implemented already by IOMMU MR and VFIO.
This defines get_attr() for the SPAPR TCE IOMMU MR which makes VFIO
call the KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE ioctl and establish
LIOBN-to-IOMMU link.
This changes spapr_tce_set_need_vfio() to avoid TCE table reallocation
if the kernel supports the TCE acceleration.
