For legacy machine types, rsdp is not in RAM, so we need a copy of rsdp
for fw cfg. We previously used g_array_free with false parameter,
but this seems to confuse people.
This also wastes a bit of memory as the buffer is unused for new
machine types.
Let's just use plain g_memdup, and free original memory together with
the array.

This fixes multiple issues around ACPI RAM management:
RSDP and linker RAM aren't currently marked dirty
on update, so they won't be migrated correctly.
Let's handle all tables in the same way: set correct size (assert if
too big), update, mark RAM dirty.
This also drops assert checking that table size didn't change: table
size is fundamentally dynamic and depends on hw configuration,
just set the correct size and use that (memory core asserts if size is
too large).
This also means we can drop tracking table size, memory core does this
for us now.

-global lets you set a nice booby-trap for yourself:

QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
Not nice. Until commit 3196270 we even abort()ed.
The same error triggers if you manage to screw up a machine type's
compat_props. To demonstrate, change HW_COMPAT_2_1's entry to
.driver = "usb-mouse",\
.property = "usb_version",\
.value = "1", \
Then run
$ qemu-system-x86_64 -usb -M pc-i440fx-2.1 -device usb-mouse
upstream-qemu: -device usb-mouse: Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
One of our creatively cruel error messages.
Since this is actually a coding error, we *should* abort() here.
Replace the error by an assertion failure in this case.
But turn the fatal error into a mere warning when the faulty
GlobalProperty comes from the user. Looks like this:
$ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Warning: global usb-mouse.usb_version=l ignored (Parameter 'usb_version' expects an int64 value or range)
(qemu)
This is consistent with how we handle similarly unusable -global in
qdev_prop_check_globals().
You could argue that the error should make device_add fail. Would be
harder, because we're running within TypeInfo's instance_post_init()
method device_post_init(), which can't fail.
