icount: update instruction counter on apic patching
kvmvapic patches the code when some instructions are executed.
E.g. mov 0xff, 0xfffe0080 is interpreted as push 0xff/call ...
This patching is also followed by some side effects (changing apic
and guest memory state). Therefore deterministic execution should take
this operation into account. This patch decreases icount when original
mov instruction is trying to execute. Therefore patching becomes
deterministic and can be replayed correctly.

hw/isa/lpc_ich9: add SMI feature negotiation via fw_cfg
Introduce the following fw_cfg files:
- "etc/smi/supported-features": a little endian uint64_t feature bitmap,
presenting the features known by the host to the guest. Read-only for
the guest.
The content of this file will be determined via bit-granularity ICH9-LPC
device properties, to be introduced later. For now, the bitmask is left
zeroed. The bits will be set from machine type compat properties and on
the QEMU command line, hence this file is not migrated.
- "etc/smi/requested-features": a little endian uint64_t feature bitmap,
representing the features the guest would like to request. Read-write
for the guest.
The guest can freely (re)write this file, it has no direct consequence.
Initial value is zero. A nonzero value causes the SMI-related fw_cfg
files and fields that are under guest influence to be migrated.
- "etc/smi/features-ok": contains a uint8_t value, and it is read-only for
the guest. When the guest selects the associated fw_cfg key, the guest
features are validated against the host features. In case of error, the
negotiation doesn't proceed, and the "features-ok" file remains zero. In
case of success, the "features-ok" file becomes (uint8_t)1, and the
negotiated features are locked down internally (to which no further
changes are possible until reset).
The initial value is zero. A nonzero value causes the SMI-related
fw_cfg files and fields that are under guest influence to be migrated.
The C-language fields backing the "supported-features" and
"requested-features" files are uint8_t arrays. This is because they carry
guest-side representation (our choice is little endian), while
VMSTATE_UINT64() assumes / implies host-side endianness for any uint64_t
fields. If we migrate a guest between hosts with different endiannesses
(which is possible with TCG), then the host-side value is preserved, and
the host-side representation is translated. This would be visible to the
guest through fw_cfg, unless we used plain byte arrays. So we do.

-----------
hw/isa/lpc_ich9: add broadcast SMI feature
The generic edk2 SMM infrastructure prefers
EFI_SMM_CONTROL2_PROTOCOL.Trigger() to inject an SMI on each processor. If
Trigger() only brings the current processor into SMM, then edk2 handles it
in the following ways:
(1) If Trigger() is executed by the BSP (which is guaranteed before
ExitBootServices(), but is not necessarily true at runtime), then:
(a) If edk2 has been configured for "traditional" SMM synchronization,
then the BSP sends directed SMIs to the APs with APIC delivery,
bringing them into SMM individually. Then the BSP runs the SMI
handler / dispatcher.
(b) If edk2 has been configured for "relaxed" SMM synchronization,
then the APs that are not already in SMM are not brought in, and
the BSP runs the SMI handler / dispatcher.
(2) If Trigger() is executed by an AP (which is possible after
ExitBootServices(), and can be forced e.g. by "taskset -c 1
efibootmgr"), then the AP in question brings in the BSP with a
directed SMI, and the BSP runs the SMI handler / dispatcher.
The smaller problem with (1a) and (2) is that the BSP and AP
synchronization is slow. For example, the "taskset -c 1 efibootmgr"
command from (2) can take more than 3 seconds to complete, because
efibootmgr accesses non-volatile UEFI variables intensively.
The larger problem is that QEMU's current behavior diverges from the
behavior usually seen on physical hardware, and that keeps exposing
obscure corner cases, race conditions and other instabilities in edk2,
which generally expects / prefers a software SMI to affect all CPUs at
once.
Therefore introduce the "broadcast SMI" feature that causes QEMU to inject
the SMI on all VCPUs.
While the original posting of this patch
<http://lists.nongnu.org/archive/html/qemu-devel/2015-10/msg05658.html>
only intended to speed up (2), based on our recent "stress testing" of SMM
this patch actually provides functional improvements.

hw/scsi: Fix debug message of cdb structure in scsi-generic
When running with debug enabled, the scsi-generic cdb that is
dumped skips byte 0 of the command, which is the opcode. This
makes identifying which command is being issued/completed a
little difficult. Example:
0x00 0x00 0x01 0x00 0x00
scsi-generic: scsi_read_data 0x0
scsi-generic: Data ready tag=0x0 len=164
scsi-generic: scsi_read_data 0x0
scsi-generic: Command complete 0x0x10a42c60 tag=0x0 status=0
Improve this by adding a message prior to the loop, similar to
what exists for scsi-disk. Clean up a few other messages to be
more explicit of what is being represented. Example:
scsi-generic: Command: data=0x12 0x00 0x00 0x01 0x00 0x00
scsi-generic: scsi_read_data tag=0x0
scsi-generic: Data ready tag=0x0 len=164

block: Fix target variable of BLKSECTGET ioctl
Commit 6f6071745bd0 ("raw-posix: Fetch max sectors for host block device")
introduced a routine to call the kernel BLKSECTGET ioctl, which stores the
result back to user space. However, the size of the data returned depends
on the routine handling the ioctl. The (compat_)blkdev_ioctl returns a
short, while sg_ioctl returns an int. Thus, on big-endian systems, we can
find ourselves accidentally shifting the result to a much larger value.
(On s390x, a short is 16 bits while an int is 32 bits.)
Also, the two ioctl handlers return values in different scales (block
returns sectors, while sg returns bytes), so some tweaking of the outputs
is required such that hdev_get_max_transfer_length returns a value in a
consistent set of units.

x86-KVM: Supply TSC and APIC clock rates to guest like VMWare
This fixes timekeeping of x86-64 Darwin/OS X/macOS guests when using KVM.
Darwin/OS X/macOS for x86-64 uses the TSC for timekeeping; it normally
calibrates this by querying various clock frequency scaling MSRs. Details
depend on the exact CPU model detected. The local APIC timer frequency is
extracted from (EFI) firmware.
This is problematic in the presence of virtualisation, as the MSRs in question
are typically not handled by the hypervisor. VMWare (Fusion) advertises TSC and
APIC frequency via a custom 0x40000010 CPUID leaf, in the eax and ebx registers
respectively. This is documented at https://lwn.net/Articles/301888/ among
other places.
Darwin/OS X/macOS looks for the generic 0x40000000 hypervisor leaf, and if this
indicates via eax that leaf 0x40000010 might be available, that is in turn
queried for the two frequencies.
This adds a CPU option "vmware-cpuid-freq" to enable the same behaviour when
running Qemu with KVM acceleration, if the KVM TSC frequency can be determined,
and it is stable. (invtsc or user-specified) The virtualised APIC bus cycle is
hardcoded to 1GHz in KVM, so ebx of the CPUID leaf is also hardcoded to this
value.

chardev: qom-ify
Turn Chardev into Object.
qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It
will call qemu_char_open() to open/intialize the chardev with the
ChardevCommon *backend settings.
The CharDriver::create() callback is turned into a ChardevClass::open()
which is called from the newly introduced qemu_chardev_open().
"chardev-gdb" and "chardev-hci" are internal chardev and aren't
creatable directly with -chardev. Use a new internal flag to disable
them. We may want to use TYPE_USER_CREATABLE interface instead, or
perhaps allow -chardev usage.
Although in general we keep typename and macros private, unless the type
is being used by some other file, in this patch, all types and common
helper macros for qemu-char.c are in char.h. This is to help transition
now (some types must be declared early, while some aren't shared) and
when splitting in several units. This is to be improved later.

ldl_p has a signed return type so assigning it to uint64_t implicitly

Example: guest performs a 32-bit write of 0x80000000 to an mmio region
