In order to convert qmp() macro to an inline function, expose a
qtest_qmpv() function, reused by qtest_qmp().
We can't apply GCC_FMT_ATTR() since fdc-test is using zero-length format
strings, which would result in warnings treated as errors.

libqtest.h provides a number of shortcut macros to avoid tests feeding
it the QTestState they operate on. Most of these can easily be turned
into static inline functions, so let's do that for clarity.
This avoids getting off-by-one error messages when passing wrong args.
Some macros had a val argument but documented @value argument. Fix this.
While touching things, enforce gtk-doc markup for return values and for
referencing types.

The new formulation makes better use of add-with-carry type insns
that the host may have. Use gcc's sign adjustment trick to avoid
having to perform a 128-bit negation.

Replace some x86_64 specific inline assembly with something that
all 64-bit hosts ought to optimize well. At worst this becomes
a call to the gcc __multi3 routine, which is no worse than our
implementation in util/host-utils.c.
With gcc 4.7, we get identical code generation for x86_64. We
now get native multiplication on ia64 and s390x hosts. With minor
improvements to gcc we can get it for ppc64 as well.

Commit 0b0d3320db (TCG: Final globals

This broke the build on 32-bit ppc. ppc64 is unaffected.

In order to instantiate a CPU subtype we will need to know which type,
so move the cpu_model splitting into cpu_x86_init().
Parameters need to be set on the X86CPU instance, so move
cpu_x86_parse_featurestr() into cpu_x86_init() as well.
This leaves cpu_x86_register() operating on the model name only.

Potentially env could be NULL whereas cpu would still be valid and
correspond to a previous env.
Wrapping this in qemu_get_cpu(), env is no longer needed, so simplify
code that existed before 55e5c28502.

Since we still need env for ppc-specific fields, obtain it via the new
env_ptr fields to avoid "cpu" name conflicts between CPUState and
PowerPCCPU for now.
This fixes a potential issue with env being NULL at the end of the loop
but cpu still being a valid pointer corresponding to a previous env.

The target-specific ENV_GET_CPU() macros have allowed us to navigate
from CPUArchState to CPUState. The reverse direction was not supported.
Avoid introducing CPU_GET_ENV() macros by initializing an untyped
pointer that is initialized in derived instance_init functions.
The field may not be called "env" due to it being poisoned.
