clock voltage divider to capacitative

adding an inductor to the clock line.
- ecn/INDEX, ecn/ecn0005.txt: new ECN discussing the switch to a
capacitative clock voltage divider. With frequency measurements.
- atusd/tests/send-20100910: measurement of transceiver performance when
placing an inductor in the 16 MHz clock line.
issues.
- atusd/ERRATA: work around the clock instability by replacing the
resistive divider with a capacitative divider
- atusd/ERRATA: a ground plane under the clock circuit would also be good to
have
- atusd/ERRATA: via near pin 1 is too close to the chip if we need to cut
wires (in DIY boards)
- atusd/sim/cdiv.sch: simulation of the capacitative divider
- atusd/ERRATA: added errata section for version 20100908
- atusd/cam/doit: increase tool clearance from 1.5 mm to 2 mm

Removed reversal of cutting direction.
- atusd/cam/pcb.pl: made area selection formulas easier to understand
board.
- atusd/atusd.sch, atusd/atusd.brd: separate MISO and MOSI and free the
extra signal we need by no longer connecting SLP_TR to the host
- atusd/atusd.sch, atusd/atusd.cmp, atusd/atusd.brd: removed reset circuit
Power-on reset seems to be sufficient.
- atusd/atusd.brd: improved AVDD ground plane

- cam/pcb.pl: advanced origin for 2nd run
- atusd/tools/lib/atusd.c: moved to tools/lib/

tools/atspi-rssi/Makefile, tools/atspi-trim/Makefile,
tools/atspi-txrx/Makefile, tools/lib/Makefile: used Makefile.common

- tools/atspi-id/atspi-id.c, tools/atspi-reset/atspi-reset.c,
tools/atspi-rssi/atspi-rssi.c, tools/atspi-trim/atspi-trim.c,
tools/atspi-txr/atspi-txr.c: updated for driver-agnostic API
- tools/atspi-id/atspi-id.c, tools/atspi-reset/atspi-reset.c,
tools/atspi-rssi/atspi-rssi.c, tools/atspi-trim/atspi-trim.c,
tools/atspi-txr/atspi-txr.c: corrected AF86RF230 typo in title
- tools/include/atspi.h, tools/lib/atspi.c, tools/lib/driver.c,
tools/lib/atusb.c: brought back support for atspi_error and
atspi_clear_error
- tools/atspi-id/atspi-id.c (atspi_get_protocol): renamed to get_protocol,
to make it clear that it's not from libatspi
- tools/atspi-id/atspi-id.c (atspi_get_build): renamed to get_build, to
make it clear that it's not from libatspi
- tools/include/atspi.h, tools/lib/atspi.c (atspi_usb_handle): new function
to obtain a driver's USB device handle (or NULL if the driver doesn't use
USB)
- 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

the board and (in the future) establish communication

is still ad hocery)
- atusd/atusd.brd: use thinner track to connect feed line to comply with
DRC
- atusd/atusd.brd: version is now 100903
- atusd/Makefile:
- AUTHORS, atusd/Makefile, atusd/dtc123.lib, atusd/dtc123je.fpd: borrowed
the DTC123 symbol (Alvaro Lopes) and footprint (Dave Ball) from
gta02-core. Note that this isn't the part I'm using in my prototype, and
I'm trying to get rid of it entirely, so all this will change before too
long.
- components/BOOKSHELF, components/INFO, components/balun.lib,
modules/Makefile, modules/INFO, modules/0805-6.fpd: added the Wuerth
748421245 balun
