Hi Anthony

This is the patches in the migration queue.  Please pull.

This includes:

- Eduardo refactorings & tests
- Matthew rate limit fix
- Zhanghaoyu CANCELLING fixes
- My bitmap changes

Integration work was done by Orit.

Happy Christmas, Juan.

      savevm.c: Coding style fix
      vmstate: Move VMState code to vmstate.c
      qemu-file: Move QEMUFile code to qemu-file.c

Juan Quintela (38):
      bitmap: use long as index
      memory: cpu_physical_memory_set_dirty_flags() result is never used
      memory: cpu_physical_memory_set_dirty_range() return void
      exec: use accessor function to know if memory is dirty
      memory: create function to set a single dirty bit
      exec: create function to get a single dirty bit
      memory: make cpu_physical_memory_is_dirty return bool
      memory: all users of cpu_physical_memory_get_dirty used only one flag
      memory: set single dirty flags when possible
      memory: cpu_physical_memory_set_dirty_range() always dirty all flags
      memory: cpu_physical_memory_mask_dirty_range() always clears a single flag
      memory: use bit 2 for migration
      memory: make sure that client is always inside range
      memory: only resize dirty bitmap when memory size increases
      memory: cpu_physical_memory_clear_dirty_flag() result is never used
      bitmap: Add bitmap_zero_extend operation
      memory: split dirty bitmap into three
      memory: unfold cpu_physical_memory_clear_dirty_flag() in its only user
      memory: unfold cpu_physical_memory_set_dirty() in its only user
      memory: unfold cpu_physical_memory_set_dirty_flag()
      memory: make cpu_physical_memory_get_dirty() the main function
      memory: cpu_physical_memory_get_dirty() is used as returning a bool
      memory: s/mask/clear/ cpu_physical_memory_mask_dirty_range
      memory: use find_next_bit() to find dirty bits
      memory: cpu_physical_memory_set_dirty_range() now uses bitmap operations
      memory: cpu_physical_memory_clear_dirty_range() now uses bitmap operations
      memory: s/dirty/clean/ in cpu_physical_memory_is_dirty()
      memory: make cpu_physical_memory_reset_dirty() take a length parameter
      memory: cpu_physical_memory_set_dirty_tracking() should return void
      memory: split cpu_physical_memory_* functions to its own include
      memory: unfold memory_region_test_and_clear()
      kvm: use directly cpu_physical_memory_* api for tracking dirty pages
      kvm: refactor start address calculation
      memory: move bitmap synchronization to its own function
      memory: syncronize kvm bitmap using bitmaps operations
      ram: split function that synchronizes a range
      migration: synchronize memory bitmap 64bits at a time
      ram: align ram_addr_t's regions in multiples of 64

Matthew Garrett (1):
      migration: Fix rate limit

Zhanghaoyu (A) (2):
      avoid a bogus COMPLETED->CANCELLED transition
      introduce MIG_STATE_CANCELLING state
