target/i386: Fix legacy page table walk
Commit b56617bbcb4 ("target/i386: Walk NPT in guest real mode") added
logic to run the page table walker even in real mode if we are in NPT
mode. That function then determined whether real mode or paging is
active based on whether the pg_mode variable was 0.
Unfortunately pg_mode is 0 in two situations:
1) Paging is disabled (real mode)
2) Paging is in 2-level paging mode (32bit without PAE)
That means the walker now assumed that 2-level paging mode was real
mode, breaking NetBSD as well as Windows XP.
To fix that, this patch adds a new PG flag to pg_mode which indicates
whether paging is active at all and uses that to determine whether we
are in real mode or not.

i386/hvf: Integrates x2APIC support with hvf accel
Support for x2APIC mode was recently introduced in the software emulated
APIC implementation for TCG. Enabling it when using macOS’s hvf
accelerator is useful and significantly helps performance, as Qemu
currently uses the emulated APIC when running on hvf as well.
This change wires up the read & write operations for the MSR VM exits
and allow-lists the CPUID flag in the x86 hvf runtime.

i386/hvf: Fix for UB in handling CPUID function 0xD
The handling for CPUID function 0xD (supported XSAVE features) was
improved in a recent patch. Unfortunately, this appears to have
introduced undefined behaviour for cases where ecx > 30, as the result
of (1 << idx) is undefined if idx > 30.
Per Intel SDM section 13.2, the behaviour for ecx values up to and
including 62 are specified. This change therefore specifically sets
all registers returned by the CPUID instruction to 0 for 63 and higher.
Furthermore, the bit shift uses uint64_t, where behaviour for the entire
range of 2..62 is safe and correct.

hw/i386/pc: Don't try to init PCI NICs if there is no PCI bus
The 'isapc' machine type has no PCI bus, but pc_nic_init() still
calls pci_init_nic_devices() passing it a NULL bus pointer. This
causes the clang sanitizer to complain:
$ ./build/clang/qemu-system-i386 -M isapc
../../hw/pci/pci.c:1866:39: runtime error: member access within null pointer of
type 'PCIBus' (aka 'struct PCIBus')
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior
../../hw/pci/pci.c:1866:39 in
This is because pci_init_nic_devices() does
&bus->qbus
which is undefined behaviour on a NULL pointer even though we're not
actually dereferencing the pointer. (We don't actually crash as
a result, so if you aren't running a sanitizer build then there
are no user-visible effects.)
Make pc_nic_init() avoid trying to initialize PCI NICs on a non-PCI
system.
