Simplified the presentation of build date information and added a

command-line utility to retrieve it.

- fw/include/atspi/ep0.h, fw/atspi/ep0.c (my_setup): merged
  ATSPI_BUILD_NUMBER and ATSPI_BUILD_DATE into single ATSPI_BUILD
- fw/atspi/ep0.c (my_setup): added work-arounds for compiler bugs
- tools/atspi-id/Makefile, tools/atspi-id/atspi-id.c: command-line utility
  to query hardware and firmware version
