84bd945cf2 i386: kvm: set CPUID_EXT_HYPERVISOR on kvm_arch_get_supported_cpuid()
Full grep for kvm_arch_get_supported_cpuid:

   kvm.h:uint32_t kvm_arch_get_supported_cpuid(KVMState *env, uint32_t function,
   target-i386/cpu.c:        x86_cpu_def->cpuid_7_0_ebx_features = kvm_arch_get_supported_cpuid(kvm_state, 0x7, 0, R_EBX);
   target-i386/cpu.c:            *eax = kvm_arch_get_supported_cpuid(s, 0xA, count, R_EAX);
   target-i386/cpu.c:            *ebx = kvm_arch_get_supported_cpuid(s, 0xA, count, R_EBX);

   target-i386/cpu.c:            *edx = kvm_arch_get_supported_cpuid(s, 0xA, count, R_EDX);
   target-i386/cpu.c:            *eax = kvm_arch_get_supported_cpuid(s, 0xd, count, R_EAX);
   target-i386/cpu.c:            *ebx = kvm_arch_get_supported_cpuid(s, 0xd, count, R_EBX);
   target-i386/cpu.c:            *ecx = kvm_arch_get_supported_cpuid(s, 0xd, count, R_ECX);
   target-i386/cpu.c:            *edx = kvm_arch_get_supported_cpuid(s, 0xd, count, R_EDX);
   target-i386/kvm.c:uint32_t kvm_arch_get_supported_cpuid(KVMState *s, uint32_t function,
   target-i386/kvm.c:        cpuid_1_edx = kvm_arch_get_supported_cpuid(s, 1, 0, R_EDX);
   target-i386/kvm.c:    env->cpuid_features &= kvm_arch_get_supported_cpuid(s, 1, 0, R_EDX);
 * target-i386/kvm.c:    env->cpuid_ext_features &= kvm_arch_get_supported_cpuid(s, 1, 0, R_ECX);
   target-i386/kvm.c:    env->cpuid_ext2_features &= kvm_arch_get_supported_cpuid(s, 0x80000001,
   target-i386/kvm.c:    env->cpuid_ext3_features &= kvm_arch_get_supported_cpuid(s, 0x80000001,
   target-i386/kvm.c:    env->cpuid_svm_features  &= kvm_arch_get_supported_cpuid(s, 0x8000000A,
   target-i386/kvm.c:        kvm_arch_get_supported_cpuid(s, KVM_CPUID_FEATURES, 0, R_EAX);
   target-i386/kvm.c:            kvm_arch_get_supported_cpuid(s, 0xC0000001, 0, R_EDX);

Note that there is only one call for CPUID[1].ECX above (*), and it is
the one that gets hacked to include CPUID_EXT_HYPERVISOR, so we can
simply make kvm_arch_get_supported_cpuid() set it, to let the rest of
the code automatically know that the flag can be safely set by QEMU.

bdeec80217 target-i386: Initialize APIC at CPU level
(L)APIC is a part of cpu [1] so move APIC initialization inside of
x86_cpu object. Since cpu_model and override flags currently specify
whether APIC should be created or not, APIC creation&initialization is
moved into x86_cpu_apic_init() which is called from x86_cpu_realize().

and it's more convenient to model after majority of them.

a1d29d6c1d configure: use -Wwombat to test whether gcc recognizes -Wno-wombat
gcc will silently accept unrecognized -Wno-wombat warning suppression
options (it only mentions them if it has to print a compiler warning
for some other reason). Since we already run a check for whether gcc
recognizes the warning options we use, we can easily make this use
the positive sense of the option when checking for support for the
suppression option. This doesn't have any effect except that it avoids
gcc emitting extra messages about unrecognized command line options
when it is printing other warning messages.
