memory: change dirty getting API to take a size
Instead of each device knowing or guessing the guest page size,just pass the desired size of dirtied memory area.

vectorize is_dup_page
is_dup_page is already proceeding in 32-bit chunks. Changing itto 16 bytes using Altivec or SSE is easy.

memory: obsolete cpu_physical_memory_[gs]et_dirty_tracking()
The getter is no longer used, so it is completely removed.

Switch ram_save to the memory API
Avoid using ram_addr_t, instead use (MemoryRegion *, offset) pairs.
Sort RAMBlocks by ID for migration, not by ram_addr
ram_addr is (a) unstable (b) going away. Sort by idstr instead.
Commit b2e0a138e initially introduced the sorting for the purposeof improving debuggability. After this patch, the order is stillstable, but perhaps less usable by a human....
Remove support for version 3 ram_load
Version 3 ram_load depends on ram_addrs, which are not stable. Version 4was introduced in 0.13 (and RHEL 6), so this means live migration from 0.12and earlier to 1.1 or later will not work.

NULL is a valid bus/device, so there is no change in behaviour.
