confd: reduce noise during normal config reload
During a normal configuration update, done via write to temp file andrename, this is what confd logs (slightly edited for clarity):
2012-12-14 01:05:53: ganeti-confd INFO Loaded new config, serial 218662012-12-14 01:06:18: ganeti-confd INFO File lost, trying to re-establish notifier...
Fix compatibility with newer Haskell libraries
This small patch fixes compatibility with a few newer Haskell libraries:
- base 4.6, included with ghc 7.6, removed the deprecated 'catch' function from Prelude, so our "import Prelude hiding (catch)" is now...
Implement a node to drbd minors query function
This can be queried remotely since it's a pure configuration query.

Further fixes for new-style exception handling
Commit 30d25dd8 moved the htools code to new-style exception handling,but the hconfd code hasn't been, which fails when compiling on newerGHC versions.
This patch does the rest of the move; however, the situation is not...
Rework exit model
While updating the confd code, I realised that we have lots ofduplication in the exit model for the various programs.
So this patch attempts to abstract all the exits via a couple of newfunctions; sorry for the somewhat big patch, but I hope the payoff is...
Update hconfd bind address handling
Instead of hardcoded IPv4 INADDR_ANY, this patch changes hconfd to useeither the any network for the configured cluster address family(ipv4/ipv6), or whatever the user passes in via the --bind option.

htools: add confd server module
This contains a more-or-less complete implementation for theserver-side confd.
Note that most of the code is behaving identical to the Python code,with a notable exception: the asyncore/inotify code was changed (sinceHaskell doesn't have asyncore) to 3-thread system. While otherwise I...
