Fix optimization bug and cleanup (#1363)

Browse source 
- Compiling Demo/Common/Minimal/TimerDemo.c with "gcc -flto" breaks the
  tests, so add "volatile" modifier to "ucOneShotTimerCounter" to fix
  this.
- In Demo/FreeRTOS_Plus_TCP_Echo_Qemu_mps2/main_networking.c print the
  network configuration even more visible.
- In MessageBufferDemo.c and Demo/Posix_GCC/main_full.c fix compiler
  warnings from "gcc -Wwrite-strings" by adding a const modifier.
