target-i386: Pass X86CPU object to cpu_x86_find_by_name()

This will help us change the initialization code to not require carrying
some intermediate values in a x86_def_t struct (and eventually kill the
x86_def_t struct entirely).

target-i386: Disable PMU CPUID leaf by default

Bug description: QEMU currently gets all bits from GET_SUPPORTED_CPUID
for CPUID leaf 0xA and passes them directly to the guest. This makes
the guest ABI depend on host kernel and host CPU capabilities, and
breaks live migration if we migrate between hosts with different...

cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"

Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code.
This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed".

The reason for the failure is that CPUClass::kvm_fd is not yet...

gdbstub: Replace GET_REG*() macros with gdb_get_reg*() functions

This avoids polluting the global namespace with a non-prefixed macro and
makes it obvious in the call sites that we return.

Semi-automatic conversion using, e.g.,
sed i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target*/gdbstub.c...

cpu: Introduce CPUClass::gdb_{read,write}_register()

Completes migration of target-specific code to new target-*/gdbstub.c.

cpu: Introduce CPUState::gdb_num_regs and CPUClass::gdb_num_core_regs

CPUState::gdb_num_regs replaces num_g_regs.
CPUClass::gdb_num_core_regs replaces NUM_CORE_REGS.

Allows building gdb_register_coprocessor() for xtensa, too.

As a side effect this should fix coprocessor register numbering for SMP....

kvm: Change prototype of kvm_update_guest_debug()

Passing a CPUState pointer instead of a CPUArchState pointer eliminates
the last target dependent data type in sysemu/kvm.h.

It also simplifies the code.

Fix real mode guest segments dpl value in savevm

Older KVM version put invalid value in the segments registers dpl field for
real mode guests (0x3).
This breaks migration from those hosts to hosts with unrestricted guest support.
We detect it by checking CS dpl value for real mode guest and fix the dpl values...
