92d9778dd7 fix race on primary switchover 
solution: wait until all in /mars/resouce-*/ has stabilized
for 60s and all known logfiles have been migrated.
This more a workaround than a solution and should be fixed
in MARS FULL.

58f6981806 fix hang of remote logfile update 
appending to logfile did not update copy_end_pos, so the copy
brick never switched off.

81bfb9471a fix network race on primary/secondary switch 
The race could lead to unnecessary split brain.
Now we wait until everything in the resource directory became stable
for at least 60 seconds. This may be somewhat too conservative
when having k>2 participants on the same resource.

1e037b4dd5 fix waiting condition 
if_switch() must not be called when requests are flying.
It is better to get a hung task instead (crashes are worse).
