coding_defs.h included defs_common.h, which pulls in many dependencies, e.g., the logging module, which pulls in T. However, it does not use anything of this. So remove, and include stdbool.h instead (because bool is used in coding_defs.h. nr_polar_defs.h relied on some includes done in coding_defs. Use includes for pthreads and SIMD to define types that are used in nr_polar_defs.h.
