Merged uSD driver into unified tool build, completed conversion of tools. - atusd/tools/lib/atusd.c: moved to tools/lib/ - atusd/tools/lib/atusd.h: removed, we can now use tools/include/atspi.h - tools/lib/atusd.c: added copyright header - tools/lib/atusd.c: updated for driver API - tools/lib/Makefile: added atusd.o - tools/Makefile.common: moved common elements from all other makefiles in tools/*/ here - tools/Makefile.common: added target-specific compiler and flags - tools/atspi-id/Makefile, tools/atspi-reset/Makefile, tools/atspi-rssi/Makefile, tools/atspi-trim/Makefile, tools/atspi-txrx/Makefile, tools/lib/Makefile: used Makefile.common - tools/lib/Makefile: differentiate USB and uSD build - tools/atspi-id/atspi-id.c, tools/atspi-reset/atspi-reset.c, tools/atspi-rssi/atspi-rssi.c, tools/atspi-trim/atspi-trim.c, tools/atspi-txr/atspi-txr.c: updated for driver-agnostic API - tools/atspi-id/atspi-id.c, tools/atspi-reset/atspi-reset.c, tools/atspi-rssi/atspi-rssi.c, tools/atspi-trim/atspi-trim.c, tools/atspi-txr/atspi-txr.c: corrected AF86RF230 typo in title - tools/include/atspi.h, tools/lib/atspi.c, tools/lib/driver.c, tools/lib/atusb.c: brought back support for atspi_error and atspi_clear_error - tools/atspi-id/atspi-id.c (atspi_get_protocol): renamed to get_protocol, to make it clear that it's not from libatspi - tools/atspi-id/atspi-id.c (atspi_get_build): renamed to get_build, to make it clear that it's not from libatspi - tools/include/atspi.h, tools/lib/atspi.c (atspi_usb_handle): new function to obtain a driver's USB device handle (or NULL if the driver doesn't use USB)
