If block used_length does not match, try to resize it.

This is v3 of the patchset.
Changes since v2:
- Address Paolo's comments: drop an unused function, fix up
comment.
Changes since v1:
- Any RAM can now be resizeable - there's no requirement
that it's device RAM any
Make cpu_physical_memory_set/clear_dirty_range
behave symmetrically.
To clear range for a given client type only, add
cpu_physical_memory_clear_dirty_range_type.

Use resizeable ram API so we can painlessly extend ROMs in the
future. Note: migration is not affected, as we are
not actually changing the used length for RAM, which
is the part that's migrated.
Use this in acpi: reserve x16 more RAM space.

Document that when using qemu_ram_resize for anything mapped into guest
address space, it's the job of the resize function to update guest
visible state.

Add API to allocate resizeable RAM MR.
This looks just like regular RAM generally, but
has a special property that only a portion of it
(used_length) is actually used, and migrated.
This used_length size can change across reboots.
Follow up patches will change used_length for such blocks at

The Power ISA square root instructions (fsqrt[s], frsqrte[s]) must

However, NaNs have no sign and therefore this flag should not

Add a degenerate implementation of the Transaction Check (tcheck)
instruction. Since transaction always immediately fail, this
implementation simply sets CR[BF] to 0b1000, i.e. TDOOMED = 1
