Hardening/style guide palib

### Description
Removed around 3300 style-guide errors from palib.
I have left 8 errors as they are especially hard to remove.
Also, a few modifications in my intents to compile under Ubuntu 14.04 are seen in CMakeLists.txt.
I prefer to save these modifications (they only affect Ubuntu 14.04).

In Ubuntu 14.04, libboost comes with the version 1.54.
I can't replace libboost with another version, as all programs that use boost would then stop working.
The only way to do this is to maintain TWO version of boost at the same time.
I decided to put the boost 1.53 in /opt (and I hope everybody agrees with that decision).

So no, this is not some 'kz specific' stuff.
This is an approach to make the broker compile and work in a system with a too new boost installed by default.
