marsadm: use actual primary where appropriate instead of target primary
...
The actual primary is decoded in 'actual-*/is-primary' links, while the
target primary is decoded in the 'primary' link. This is not clearly
taken into account in several functions of marsadm. This commit fixes
this problem.
- Added _get_actual_primary() function
- Remove $pri parameter in _primary_res
- Use _get_actual_primary() where actual state should be used

marsadm: fix check_primary/check_not_primary to use actual state ('is-primary')
...
The actual state is decoded in 'actual-*/is-primary' links, while the target
state is decoded in the 'primary' link.
- check_primary() now uses actual state
- check_not_primary() now uses both actual state and target state

marsadm: allow switchback to primary when I am actually primary
...
For example, when /dev/mars/something is mounted or in another use,
switching to secondary will only succeed after the device has
been closed. During this intermediate state, we allow to switch
back to primary without checking all the big checks.

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.

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.
