0953801a6e marsadm: fix primary detection 
The actual-*/is-primary symlink may race with the appearance
of the device. Use both conditions to be sure.

dab60da817 marsadm: allow calling multiple functions in phases 
Add infrastructure for splitting commands in multiple phases.
Usually, phase0 will check for some preconditions, while
phase1 will execute the command. The final result will only
be committed if nothing fails.

The difference to the old behaviour will only show up when combined
with 'all' resources. If anything fails in phase0, nothing will be
touched in phase1. The old behaviour could touch some resources,
but omit others when something failed.

The new behaviour is more transactional-like.

92951e491b marsadm: improve primary/secondary command behaviour 
Previously, the 'marsadm primary' and 'marsadm secondary' commands
were successful as soon as the target primary was successfully set
to the new primary or '(none)', respectively.  This commit appends
a check to wait until the primary is really changed (actual state).

Changes in marsadm:
- Added check_primary_settled() function
- Do not use local variable named '$host' in _primary_res() since
  a global variable with same name exists.
- Do not use/set global variable '$host' in primary_res().  Use
  local variable '$new' initially set to '$host' instead.
- Make 'secondary' command idempotent ("is already secondary")
- Call trigger() and check_primary_settled() in primary_res()

Related minor changes:
- marsadm: Added optional parameter 'sleeptime' to sleep_timeout()
- Removed debug output in check_file_aged()

4dafa9467a 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

5d3d777b86 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

5fc1844eba 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.
