hw/arm/virt: fix pl031 addr typo

pl031's base address should be 0x9010000, not 0x90010000, otherwise
it sits in ram when configuring a guest with greater than 1G.

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.

virtio-rng: Move error-checking forward to prevent memory leak

This patch pushes the error-checking forward and the virtio
initialization backward in the device realization function
in order to prevent memory leaks for hot plug scenarios.

checker: ignore fields marked unused

While comparing qemu-1.0 json output with qemu-2.1, a few fields got
marked unused.  These need to be skipped over, and not flagged as
mismatches.

For handling unused fields, the exact number of bytes need to be skipped
over as the size of the unused field.

Currently, only the term "unused" is matched.  When more field names
turn up, this will have to be updated based on the whitelist matching
method to match more such terms.

hw/arm/boot: Set PC correctly when loading AArch64 ELF files

The code in do_cpu_reset() correctly handled AArch64 CPUs
when running Linux kernels, but was missing code in the
branch of the if() that deals with loading ELF files.
Correctly jump to the ELF entry point on reset rather than
leaving the reset PC at zero.

Add some spacing and zeros to make it easier to read and

all the addresses are as they should be - thanks to the new
formatting ;-)
