Added graphical display of RSSI scan results.
- tools/Makefile.common: CFLAGS and OBJS can now be target-specific - tools/atspi-rssi/Makefile: add SDL, SDL_gfx, and the GUI object files when building on the host - tools/atspi-rssi/Makefile: set -DHAVE_GFX when building on the host - tools/atspi-rssi/atspi-rssi.c (usage, main): new option -g to use GUI mode - tools/atspi-rssi/atspi-rssi.c (main): rename variable for the number of sweeps in non-GUI mode from "sweeps" to "arg", since it may have other uses in the future - tools/atspi-rssi/digit.h, tools/atspi-rssi/digit.c: draw 7 segment style digits - tools/atspi-rssi/zgrid.h, tools/atspi-rssi/zgrid.c: display a surface in faux 3D with SDL/SDL_gfx - tools/tools/atspi-rssi/gui.h, tools/atspi-rssi/gui.c: display RSSI scans as a scrolling 3D profile
