Werner Almesberger a18d5969bd Next part of board bringup: reset and power cycling.
- atusd/ERRATA: one more problem: the transistor footprint is wrong
- atusd/tools/lib/atusd.c (atusd_cycle, atusd_reset): added power cycling and
  hardware reset
- atusd/tools/lib/atusd.h: be nice and make a header file
- atusd/tools/try.c: be nice and use header files (caught a bug as well)

- changed C7 to 1 nF to debug a signal attenuation problem. Turned out to be
a bad trace. According to simulations, 22 pF should be more than enough.
- added wire connecting uSD-side ground plane to ground plane at outer edge,
to improve CLK signal return. (Probably unnecessary, too.)
- the footprint of the transistor (Q1) is reversed :-( It works after
converting the chip from SOT to PLCC.
