syncdaemon: provide transactional semantics to config file writing

2011-04-04T15:02:22+00:00

So updating the config file from multiple contexts won't mess it up.
This prepares the next commit where we'll set options internaly (which lacks
the serial nature of user actions).

syncdaemon: give some refactoring to cascading code

2011-04-04T15:02:18+00:00

- expiry check of foreign volinfo moved back to GLUSTERServer,
  so that under the hood we can removexattr the expired ones;
  a nice side-effect is that we can use the same dict layout
  for foreign and native volinfo (ie., foreign needs no
  timeout field)
- get_volinfo() is renamed to get_sys_volinfo() and most of the logic
  is stripped off of it (what remained there is the check
  against foreign master ambiguity)
- volinfo transition logic is cut out to an almost purely functional
  static method (only impurity is the exeption raised upon
  forbidden volinfo change)
- ping renamed to keep-alive, as something called "ping" is
  not supposed to have payload (yeah, keep-alive is a bit fishy
  on this front too, but could not come up with better...)
