target/i386: Rename helper_fldt, helper_fstt
Change the prefix from "helper" to "do". The former should be
reserved for those functions that are called from TCG; the latter
is in use within the file already for those functions that are
called from the helper functions, adding a "retaddr" argument.

target/i386: Split out do_fsave, do_frstor, do_fxsave, do_fxrstor
The helper_* functions must use GETPC() to unwind from TCG.
The cpu_x86_* functions cannot, and directly calling the
helper_* functions is a bug. Split out new functions that
perform the work and can be used by both.

accel-cpu: make cpu_realizefn return a bool
overall, all devices' realize functions take an Error **errp, but return void.
hw/core/qdev.c code, which realizes devices, therefore does:
local_err = NULL;
dc->realize(dev, &local_err);
if (local_err != NULL) {
goto fail;
}
However, we can improve at least accel_cpu to return a meaningful bool value.

Later on we should add a check that asserts this easily f.e.:
static bool check_cpl0(DisasContext *s)
{
int cpl = s->cpl;
#ifdef CONFIG_USER_ONLY
assert(cpl == 3);
#endif
if (cpl != 0) {

return false;

accel: add init_accel_cpu for adapting accel behavior to CPU type
while on x86 all CPU classes can use the same set of TCGCPUOps,
on ARM the right accel behavior depends on the type of the CPU.
So we need a way to specialize the accel behavior according to
the CPU. Therefore, add a second initialization, after the
accel_cpu->cpu_class_init, that allows to do this.

We will reuse the page walker for both SVM and regular accesses. To do
so we will build a function that receives the currently active paging
mode; start by including in cpu.h the constants and the function to go
from cr4/hflags/efer to the paging mode.

target/i386: extend pg_mode to more CR0 and CR4 bits
In order to unify the two stages of page table lookup, we need
mmu_translate to use either the host CR0/EFER/CR4 or the guest's.
To do so, make mmu_translate use the same pg_mode constants that
were used for the NPT lookup.
This also prepares for adding 5-level NPT support, which however does
not work yet.

configure: fix detection of gdbus-codegen
"pkg-config --variable=gdbus_codegen gio-2.0" returns "gdbus-codegen",
and it does not pass test -x (which does not walk the path).
Meson 0.58.0 notices that something is iffy, as the dbus_vmstate1
assignment in tests/qtest/meson.build uses an empty string as the
command, and fails very eloquently:
../tests/qtest/meson.build:92:2: ERROR: No program name specified.
Use the "has" function instead of test -x, and fix the generation
of config-host.mak since meson.build expects that GDBUS_CODEGEN
is absent, rather than empty, if the tool is unavailable.
