Various parts of the migration code do different things when they're in postcopy mode; prior to this patch this has been 'postcopy-active'. This patch extends 'in_postcopy' to include 'postcopy-paused' and 'postcopy-recover'. In particular, when you set the max-postcopy-bandwidth parameter, this only affects the current migration fd if we're 'in_postcopy'; this leads to a race in the postcopy recovery test where it increases the speed from 4k/sec to unlimited, but that increase can get ignored if the change is made between the point at which the reconnection happens and it transitions back to active.
