Traces leaving a pad on the side may invite solder bridges to "false pads"
exposed at the edges of the chip, with unknown consequences.
- atusb.brd: make trace from P0.0 (IRQ_RF) leave pad at the front, not
at the side
- atusb.brd: make trave from P0.7 (SCLK) leave pad at front, not at the
side

nRST and VDD within reach (pull-up suggested by Joerg Reisenweber)

common/Makefile.common

- usb.sch: use P0.2 as board revision ID pin
- atrf.sch: label feed line
- atusb.brd: set feed line width via design rule, not as user size

(10% enlarged)
- atusb/atusb.cmp (CON1): change from "miniUSB_B" USB receptacle to
"USB-A-PLUG-SMT" plug
- atusb/atusb.cmp (VR1, VR2, VR3): update value from schematics
We know from CNTR that the capacitance of the 0603 TVS (EPCOS CT0603M4G,
200 pF) is too large and can disturb the USB signal. The 0402 TVS
(Panasonic EZJ-P0V080GA, 100 pF) works much better.
Since we have lots of 0402 components already, just change the remaining
0603 to 0402, too.

soldering
This way, we can plug the device into a USB port, like a USB stick.
We use a real plug (instead of shaping the PCB in the form of a plug)
for better mechanical stability.
- atusb.pro: change from components/mini_usb_b to components/usb_a_plug
- usb.sch (CON1): replace MINI_USB_B with USB_A_PLUG
The C2 pads were originally sized for permanently soldering a 100 mil
header. For development, a temporary connection is sufficient. Eventually,
we will just use pogo pins to make this connection.
- usb.sch: changed C2 pads from PAD_120x60 to PAD_60x60
- usb.sch: added comment that pads should be spaced at 100 mil interval

command ATSPI_TEST to enter test mode
- include/atspi/ep0.h (EP0ATSPI_MINOR): bumped protocol to version 0.1
- include/at86rf230.h: corrected comment before TRX_CMD field to indicate
that the register is called TRX_STATE
- 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
- atrf/: rename to atusb/
- atrf/wpan-atrf.pro, atrf/wpan-atrf.sch, atrf/wpan-atrf.brd,
