Introduce library with ATSPI access functions (largely untested)
- tools/include/atspi.h, tools/lib/Makefile, tools/lib/atspi.c: library with ATSPI access functions - tools/atspi-id/Makefile: use libatspi - tools/atspi-id/atspi-id.c (main) use atspi_open instead of open_usb - fw/atspi/at86rf230.h: moved to fw/include/ - fw/include/at86rf230.h: added ID registers - fw/atspi/ep0.c: removed stray #endif
