migration: add postcopy migration of dirty bitmaps
Postcopy migration of dirty bitmaps. Only named dirty bitmaps are migrated.
If destination qemu is already containing a dirty bitmap with the same name
as a migrated bitmap (for the same node), then, if their granularities are
the same the migration will be done, otherwise the error will be generated.
If destination qemu doesn't contain such bitmap it will be created.
