- tools/atspi-txrx/atspi-txrx.c: cleaned up includes - we need stdint.h but we don't need atspi/ep0.h - tools/atspi-txrx/atspi-txrx.c (wait_for_interrupt), tools/include/misctxrx.h (wait_for_interrupt), tools/lib/Makefile (OBJS), tools/lib/misctxrx.c (wait_for_interrupt): moved wait_for_interrupt from atspi-txrx to the atspi library, so that we can share it
