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).

This is someting need for Ubuntu 14.04 in general or for your particular Ubuntu 14.04 setup?

In don't like too much having it in the later case (as files in the repository has to be "neutral" from a point of view of particular developers envoriments). However, it you really need to have that link_directory clauses there, I would add a comment above it in a the line just before, e.g:

```
# This line was used in the Ubuntu 14.04 tests in Ken's environment
```
