for SOT-323 package with clockwise (normal) or counter-clockwise
(transistors) pin numbering

- atusb/atrf.sch (C6, C7): use canonical name 820fF instead of 0.82pF
- atusb/usb.sch (VR1, VR2, VR3): changed value from 5V6 to 5V5 for
compatibility with selected part
- atusb/atusb.sch: commit noise
- atusb/atusb.brd: reloaded for value changes

- tools/Makefile.common (CFLAGS): change fw/ include location from atrf/
to atusb/
- cntr/cntr.sch (VR1, VR2, VR3): reverted change to 0402, because this
would be too difficult to route with current board
- cntr/cntr.sch (VR1, VR2, VR3): change voltage from 5.6 V to 5.5 V,
for compatibility with selected part
- cntr/cntr.brd: updated for value change
- bom/Makefile: simplify atusd.ord and atusd.par rule by using $^
- bom/Makefile: use pattern rule for atusd.ord and atusd.par
- bom/Makefile: since we can't have more than one percent sign on a
dependency, add vpath
- bom/Makefile: use pattern rule for show-atusd. We also have to remove
show-atusd from .PHONY because implicit rules are not applied to phony
targets.

- usrp/step: the default number of runs (10) can now be overridden on the
command line
- usrp/step: usrp2_rx_cfile.py likes to busy loop from time to time. Add
a CPU time limit to prevent this from getting out of hand.
