[bind10-dev] Statistics prototype

[Naoki Kambe]

All,

We(JPRS) are just planning to implement this prototypes.

 - Stats daemon
   -- It gathers counters/status from stub module via c-channel.
   -- It stores counters/status into database for HTTP and SNMP
      module.

 - Stub module (ex. Query module)
   -- It is a sample module, example for query module, which has
      statistics counters.
   -- It keeps incremental counters and changes of status.
   -- It answers counters/status to the stats daemon.

We are planning to write the prototypes in Python.

We are now defining message format of communication between stats
daemon and stub module.

We are planning to gather following counters and status in this
prototype. We can change/add/delete from this if necessary.
