  qcow2: try load bitmaps only once

Checking reopen by existence of some bitmaps is wrong, as it may be
some other bitmaps, or on the other hand, user may remove bitmaps. This
criteria is bad. To simplify things and make behavior more predictable
let's just add a flag to remember, that we've already tried to load
bitmaps on open and do not want do it again.

  iotests: fix 169

Improve and fix 169:
    - use MIGRATION events instead of RESUME
    - make a TODO: enable dirty-bitmaps capability for offline case
    - recreate vm_b without -incoming near test end

This (likely) fixes racy faults at least of the following types:

    - timeout on waiting for RESUME event
    - sha256 mismatch on line 136 (142 after this patch)
    - fail to self.vm_b.launch() on line 135 (141 now after this patch)

And surely fixes cat processes, left after test finish.

  Merge remote-tracking branch 'remotes/maxreitz/tags/pull-block-2018-04-16' 
into staging

A fix for handling dirty bitmaps stored in qcow2 files.  This is not
absolutely necessary for 2.12, but if there is an rc4, it should go in.
