2d400d15a02dca3b7b90761b2f0bb2322e99e11a mirror: implement mirror_change method
which allows switching the @copy-mode from 'background' to
'write-blocking'.
This is useful for management applications, so they can start out in
background mode to avoid limiting guest write speed and switch to
active mode when certain criteria are fulfilled.
In presence of an iothread, the copy_mode member is now shared between
the iothread and the main thread, so turn accesses to it atomic.
