  migration: Fix typos in bitmap migration comments (2020-07-27 15:42:21 -0500)

----------------------------------------------------------------
bitmaps patches for 2020-07-27

- Improve handling of various post-copy bitmap migration scenarios. A lost
bitmap should merely mean that the next backup must be full rather than
incremental, rather than abruptly breaking the entire guest migration.
- Associated iotest improvements
