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.

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.

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.
