set a c/c++ standard for all osmocom core network projects

Hi, I would like to start a discussion to set for all osmocom core network projects a language standard (could be also set for other osmocom projects). The current state is the code is compiled with the compilers choice of c/c++. This produce unexpected build failures on newer or older system. I would like to start setting it to c11/c++11 + gnu extensions. This is a more random choice of standard. I would argue to have at least c99 for c. Any feedback?
