This is a separate patch set, it derived from
https://www.mail-archive.com/address@hidden/msg456004.html
There are several possible use cases:
1. solve issue with postcopy live migration and shared memory.
OVS-VSWITCH requires information about copied pages, to fallocate
newly allocated pages.
2. calculation vCPU blocktime
for more details see
https://www.mail-archive.com/address@hidden/msg456004.html
3. Recovery after fail in the middle of postcopy migration
Declaration is placed in two places include/migration/migration.h and into
migration/postcopy-ram.h, because some functions are required in virtio.

migration: postcopy_place_page factoring out
migration: add bitmap for copied page
