Commits fc8c5b8c41 (Makefile.user: Define
CONFIG_USER_ONLY for libuser/) and
dd83b06ae6 (qom: Introduce CPU class)
specifically prepared the qom/cpu.c file to be compiled differently for
softmmu and *-user. This broke as part of build system refactorings
while CPU patches were in flight, adding conditional fields
kvm_fd (8737c51c04) and
kvm_vcpu_dirty (20d695a925) for softmmu.
linux-user and bsd-user would therefore get a CPUState type with
instance_size ~8 bytes longer than expected.
Fix this by unconditionally having the fields in CPUState.
In practice, target-specific CPU types' instance_size would compensate
this, and upstream qom/cpu.c does not yet touch any affected field.

Setting tsc-frequency from x86_def_t is NOP because default tsc_khz
in x86_def_t is 0 and CPUX86State.tsc_khz is also initialized to 0
by default. So there is no need to overwrite tsc_khz with default 0
because field was already initialized to 0.
Custom tsc-frequency setting is not affected due to it being set
without using x86_def_t.

Move custom features parsing after built-in cpu_model defaults are set
and set custom features directly on CPU instance. That allows to make a
clear distinction between built-in cpu model defaults that eventually
should go into class_init() and extra property setting which is done
after defaults are set on CPU instance.
Impl. details:
* use object_property_parse() property setter so it would be a mechanical
change to switch to global properties later.
* And after all current features/properties are converted into static
properties, it will take a trivial patch to switch to global properties.
Which will allow to:
* get CPU instance initialized with all parameters passed on -cpu ...
cmd. line from object_new() call.
* call cpu_model/featurestr parsing only once before CPUs are created
* open a road for removing CPUxxxState.cpu_model_str field, when other
CPUs are similarly converted to subclasses and static properties.
- re-factor error handling, to use Error instead of fprintf()s, since
it is anyway passed in for property setter.

Commit 8935499831 makes cpuid return to guest host's vendor value
instead of built-in one by default if kvm_enabled() == true and allows
to override this behavior if 'vendor' is specified on -cpu command line.
But every time guest calls cpuid to get 'vendor' value, host's value is
read again and again in default case.
It complicates semantics of vendor property and makes it harder to use.
Instead of reading 'vendor' value from host every time cpuid[vendor] is
called, override 'vendor' value only once in cpu_x86_find_by_name(), when
built-in CPU model is found and if(kvm_enabled() == true).
It provides the same default semantics
if (kvm_enabled() == true) vendor = host's vendor
else vendor = built-in vendor
and then later:
if (custom vendor) vendor = custom vendor
'vendor' value is overridden when user provides it on -cpu command line,
and there is no need for vendor_override field anymore, remove it.

Vendor property setter takes string as vendor value but cpudefs
use uint32_t vendor[123] fields to define vendor value. It makes it
difficult to unify and use property setter for values from cpudefs.
Simplify code by using vendor property setter, vendor[123] fields
are converted into vendor[13] array to keep its value. And vendor
property setter is used to access/set value on CPU.
- Make for() cycle reusable for the next patch by adding
x86_cpu_vendor_words2str()
Intel's CPUID spec[1] says:
"
5.1.1 ...
These registers contain the ASCII string: GenuineIntel
...
"
List[2] of known vendor values shows that they all are 12 ASCII
characters long, padded where necessary with space.
Current supported values are all ASCII characters packed in
ebx, edx, ecx. So lets state that QEMU supports 12 printable ASCII
characters packed in ebx, edx, ecx registers for cpuid(0) instruction.
