1b4805464a marsadm: workaround concept bug in _get_actual_primary(), deprecate it 
The conceptual bug was leading to systematic false-positive failures in the
old test_suite. These failures were depeding on the _names_ of the
involved hosts: just run it on a pair of differently named hosts
following different naming conventions, and 50 out of 90 testcases
were failing false-positively.

b749ed561c userspace: add bugfix for Debian udev rules 
Patch received from Jörg Mann by email.

Some Debian versions seem to have typos in their udev rules.
As a consequence, /dev/mars/mydata does not disappear when
leaving primary state.

Other consequences might also exist. In an unreproduced case the
/dev/mars/ object was unlinked while the mount was continuously
active, without causing any harm to operations (besides that
xfs_growfs did not work, which led to the discovery of the
mysterious situation).

Probably the udev userspace may require further fixes.

Fortunately, udev-less systems (as those used by me for testing) are
not affected.

767bb03060 marsadm: allow overrides of "marsadm secondary" in disconnected clusters 
When the communication is down in partitioned clusters, the command
"marsadm seconodary" would normally use the current timestamp of
the command execution for the Lamport update protocol.

Make an exception for the case that a concurrent "marsadm primary"
was given somewhere else on a disconnected / partitioned node: let
the "primary" always win over a "secondary" command.

45f462026f marsadm: fix leave-resource cleanup 
Now the sequence leave-resource ; join-resource should work.

When the last member of the resource has gone and create-resource is
tried anew, there is a new saftey measure: the old resource directory
is left over deliberately, thus the new create-resource will deny creation
because some unreachable cluster node may have existed, such that we
didn't even know of its resource membership. This very special
case requires --force and some handwork cleanup.

dca17cb9b1 marsadm: change defaults for *{,-local,-global} 
By default, {dis}connect and {pause,resume}-{replay,sync} should
only switch the _local_ buttons. Otherwise, unexpected side-effects
could result at bigger clusters (#nodes >> 2) from a human point of view.

The new behaviour is different from DRBD, but DRBD was (until recently)
only working on _pairs_, so global spreadout was impossible.

Global switching may be requested at any time by appending suffix
"-global", which is just no longer the default in MARS.

If anyone has objections, it is straightforward to change the
defaults again.

62a2dea515 marsadm: remove timestamp functions 
Timestamps of symlinks are used for Lamport comparison
(any newer one overwrites any older one).

That concept should _not_ be used for any other comparison, since
there is no / not yet any "transactional" property of
bulk updates of symlinks (the Lamport condition treats each
symlink independently from any other).

Until such "transactions" are introduced at the strategy layer,
timestamp comparisons between _different_ symlinks are
unmeaningful in general.

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
