  xen: fix usage of ENODATA

ENODATA doesn't exist on FreeBSD, so ENODATA errors returned by the
hypervisor are translated to ENOENT.

Also, the error code is returned in errno if the call returns -1, so
compare the error code with the value in errno instead of the value
returned by the function.

  tap-bsd: implement a FreeBSD only version of tap_open

The current behaviour of tap_open for BSD systems differ greatly from
it's Linux counterpart. Since FreeBSD supports interface renaming and
tap device cloning by opening /dev/tap, implement a FreeBSD specific
version of tap_open that behaves like it's Linux counterpart.

This is specially important for toolstacks that use Qemu (like Xen
libxl), in order to have a unified behaviour across suported
platforms.

  qemu: support xen hvm direct kernel boot

qemu side patch to support xen HVM direct kernel boot:
if -kernel exists, calls xen_load_linux(), which will read kernel/initrd
and add a linuxboot.bin or multiboot.bin option rom. The
linuxboot.bin/multiboot.bin will load kernel/initrd and jump to execute
kernel directly. It's working when xen uses seabios.

During this work, found the 'kvmvapic' is in option_rom list, it should
not be there in xen case. Set s->vapic_control = 0 in xen_apic_realize()
to handle that.
