  vmstate: Make VMSTATE_STRUCT_POINTER take type, not ptr-to-type

The VMSTATE_STRUCT_POINTER macros are a bit odd in that they
must be passed an argument "FooType *" rather than just taking
the FooType. They're only used in one place, so it's easy to
tidy this up. This also lets us use the macro to replace the
hand-rolled VMSTATE_PTIMER.

  exec: fix ram_list dirty map optimization

The ae2810c4bb3b383176e8e1b33931b16c01483aab patch introduced
optimization for ram_list.dirty_memory update. However it can only
work correctly if hpratio is 1 as the @bitmap parameter stores 1 bits
per system page size (may vary, 4K or 64K on PPC64) and
ram_list.dirty_memory stores 1 bit per TARGET_PAGE_SIZE
(which is hardcoded to 4K).

This fixes hpratio!=1 case to fall back to the slow path.

  migration:fix free XBZRLE decoded_buf wrong

When qemu do live migration with xbzrle, qemu malloc decoded_buf
at destination end but free it at source end. It will crash qemu
by double free error in some scenarios. Splitting the XBZRLE structure
for clear logic distinguishing src/dst side.
