i386: do kvm_put_msr_feature_control() first thing when vCPU is reset
kvm_put_sregs2() fails to reset 'locked' CR4/CR0 bits upon vCPU reset when
it is in VMX root operation. Do kvm_put_msr_feature_control() before
kvm_put_sregs2() to (possibly) kick vCPU out of VMX root operation. It also
seems logical to do kvm_put_msr_feature_control() before
kvm_put_nested_state() and not after it, especially when 'real' nested
state is set.

Make sure env->nested_state is cleaned up when a vCPU is reset, it may
be stale after an incoming migration, kvm_arch_put_registers() may
end up failing or putting vCPU in a weird state.

scsi: Reject commands if the CDB length exceeds buf_len
In scsi_req_parse_cdb(), if the CDB length implied by the command type
exceeds the initialized portion of the command buffer, reject the request.
Rejected requests are recorded by the `scsi_req_parse_bad` trace event.
On example of a bug detected by this check is SunOS's use of interleaved
DMA and non-DMA commands. This guest behavior currently causes QEMU to
parse uninitialized memory as a SCSI command, with unpredictable
outcomes.
With the new check in place:
* QEMU consistently creates a trace event and rejects the request.
* SunOS retries the request(s) and is able to successfully boot from
disk.

When a SCSI command is received from the guest, the CDB length implied

unpredictable behavior.
Adds the buf_len parameter to scsi_req_new() and plumbs it through the

esp: Handle CMD_BUSRESET by resetting the SCSI bus
Per investigation on the linked ticket, SunOS issues a SCSI bus reset
to the ESP as part of its boot sequence. If this ESP command doesn't
cause devices to assert sense flag UNIT ATTENTION, SunOS will consider
the CD-ROM device to be non-compliant with Common Command Set (CCS).
In this condition, the SunOS installer's early userspace doesn't set
the installation source location to sr0 and the miniroot copy fails.

ppc/ppc4xx: Introduce a DCR device model
The Device Control Registers (DCR) of on-SoC devices are accessed by
software through the use of the mtdcr and mfdcr instructions. These
are converted in transactions on a side band bus, the DCR bus, which
connects the on-SoC devices to the CPU.
Ideally, we should model these accesses with a DCR namespace and DCR
memory regions but today the DCR handlers are installed in a DCR table
under the CPU. Instead, introduce a little device model wrapper to hold
a CPU link and handle registration of DCR handlers.
The DCR device inherits from SysBus because most of these devices also
have MMIO regions and/or IRQs. Being a SysBusDevice makes things easier
to install the device model in the overall SoC.

ppc/ppc405: QOM'ify CPU
Drop the use of ppc4xx_init() and duplicate a bit of code related to
clocks in the SoC realize routine. We will clean that up in the
following patches.
ppc_dcr_init() simply allocates default DCR handlers for the CPU. Maybe
this could be done in model initializer of the CPU families needing it.
