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

/*
* SDCC 2.8.0 had a number of code generation bugs that appeared in the big
* switch statement of my_setup. SDCC_FORCE_UPDATE forced the value of the
* "size" variable to be written to memory. This work-around doesn't seem
* to be necessary with 2.9.0, but we keep it around, just in case.
*
* Unfortunately, the setup->bRequest garbling bug is still with us. Without
* the evaluation forced with SDCC_FORCE_EVAL, sdcc gets confused about the
* value of setup->bRequest and then rejects all SETUP requests.
