* Added SensorConfig and DCDBPublicSensor classes as interface for dcdbconfig
* Fixed bugs and tested:
  --> CollectAgent fully working
  --> dcdbconfig fully working

* Bump cpp-driver to 2.0.1
* Create new SensorId header/source that takes over the logic
  previously found in SensorDataStore related to populating
  SensorId structs from MQTT topic strings and serializing
  them into Byte Arrays to be used as Cassandra Row Keys.

* Bumped Cassandra to 2.1.5
* Bumped cpp-driver to 2.0
* Eliminated cassandraBackend in favor of DCDBConnection

In the future, a DCDBConnection handles the low-level connection
to Cassandra. On top of an established DCDBConnection, you can
create a SensorDataStore object which gives you access to raw
sensor readings.

Use the -r option to get raw values instead.

Finalized the documentation effort of DCDBLib and updated the Makefile to do dependency checking for the make docs target.

Yet another small change to the OpenIPMI patch as 12.04 in my config seems to run autoconf/automake itself resulting in the reintroduction of the ncurses dependency.
DCDBLib build now has the correct parameters to build a Linux shared libary. Also DCDBLib now shows the hint on setting LD_LIBRARY_PATH/DYLD_LIBRARY_PATH again.
CollectAgent needs -lthrift to link (because otherwise the missing symbols from libdcdb.so will remain unresolved).
Top level Makefile now detects the number of CPU cores under Linux and adjusts MAKETHREADS variable automatically.

Moved all of CollectAgent's Cassandra related stuff to DCDBLib.
Bumped Cassandra to 1.2.13.
Minor build system improvements.

   Thrift --> 0.9.1
   Cassandra --> 1.2.10
   OpenIPMI --> 2.0.19

This results in a much cleaner collectagent.cpp file and main function.
However, further cleanups are necessary and the respective TODOs can be
found in the code.

Cross platform issues compiling C++11 code (Mac OS has two C++ standard libraries, only one supports C++11 but Thrift fails to build with it).
Fix: Replace C++11 system_error with Boost system_error.
Some other minor fixes.

Removed mosquitto dependency entirely. Started reworking collectagent main routines and message handling.

stream works. Fixed a race condition to the message threads struct pollfd fds
array.

Cassandra Header Fixes are applied only once now.

again.

values into the data store. Also shows the achieved message rate. Still
pretty dirty and naive.

Currently, this is only a proof of concept for using the Thrift API
provided by Cassandra a bit from C++. Let's hope to evolve this into
what we're aiming for, soon.
