changed from 644 to 755, which is not wanted.

Use common log mechanism in layer 3, mapping specific macros to common ones and extending common log utilities to support specific layer3 requirements

Note: this commit is work in progress. Contains initial integration of NFAPI data structures which are tested for TX path. RX path to follow.

dlsim_tm4 was crashing on massive. It was a problem
