Lionel Gauthier e7921f03a3 Changed default DRB id from 3 to 1 
With folowwing implicit rule
drb id = x => correspondind lc id = x+2, eps bearer id = x+4

Changed RLC inner structs, no more statically allocated array, now it is dynamic via malloc and collection of RLC entities are stored in a hashtable.
Changed misc simple types
Started compiling with all warning setted and treated as errors, still working on RLC and around...
Add const qualifier wherever suitable (for example param frame, module id, const pointers, etc)

Thinking about a type of context parameter in procedure calls in L2 data plane (modules id, frame, srb flag, enb flag, etc)...
