From: Fabian Grünbichler <f.gruenbichler@proxmox.com>
heavily based on/practically forked off iotest 257 for bitmap backups,
but:
- no writes to filter node 'mirror-top' between completion and
finalization, as those seem to deadlock?
- extra set of reference/test mirrors to verify that writes in parallel
with active mirror work
Intentionally keeping copyright and ownership of original test case to
honor provenance.
The test was originally adapted by Fabian from 257, but has seen
rather big changes, because the interface for mirror with bitmap was
changed, i.e. no @bitmap-mode parameter anymore and bitmap is used as
the working bitmap.

[FE: rebase for 9.0
adapt to changes to mirror bitmap interface
rename test from '384' to 'bitmap-sync-mirror']
