atrf-path: option -P to load a min/max profile; pass/fail indication in GUI

Browse Source 
- sweep.h (MIN_DIFF, MAX_DIFF, struct sweep): added min/max profile
- sweep.h (do_sweep), atrf-path.c (do_half_sweep, do_sweep): compare
  result against limits and return pass/fail decision
- sweep.h (N_CHAN), atrf-path.c (do_half_sweep, do_sweeps), gui.c
  (N_CHAN): declare number of channels in one central place instead of
  scattering it all around the program
- atrf-path.c (do_read_profile, read_profile, usage, main): new option -P
  to read a min/max profile
- gui.c (indicate, main): moved indicator to separate function and
  improved blink logic
- gui.c (OVER_RGBA, UNDER_RGBA, indicate, main): change color to indicate
  pass/fail
