Board bringup: talk to the chip and read IDs.

Browse Source 
- atusd/ERRATA: mention that the reset circuit can go, as expected
- atusd/tools/Makefile: add include path to at86rf230.h
- atusd/tools/lib/atusd.c: include atusd.h, for consistency checking
- atusd/tools/lib/atusd.c (spi_begin, spi_end, spi_data_in, spi_data_out,
  spi_send_partial, spi_recv, spi_finish, spi_send): low-level functions
  to access our modified SPI
- atusd/tools/lib/atusd.h, atusd/tools/lib/atusd.c (atusd_reg_write,
  atusd_reg_read): register read and write access
- atusd/tools/try.c: read and print chip IDs
