4d49921b9b Added user-space counter utility. 
- cntr/tools/Makefile: the usual recursive Makefile
- cntr/tools/cntr/Makefile, cntr/tools/cntr/cntr.c: user-space tool to
  periodically read the free-running counter and to calculate frequency
  and deviation from it

81ab679fbd The parasitic capacitance of the three probe input pins and R1 formed a 
quite formidable low-pass filter that almost completely eliminated the
1 MHz signal.

- cntr/cntr.sch, cntr/cntr.brd: changed R1 from 100k to 1k to increase
  input bandwidth

3584b5b736 Got "cntr" to show signs of life. It was the watchdog, as usual. 
- TODO: "cntr" now makes it to DFU and beyond
- atrf/fw/common/config.h (PLATFORM_SETUP): rename to PLATFORM_ENTER
- cntr/fw/common/config.h (PLATFORM_SETUP): rename to PLATFORM_ENTER and
  make the new PLATFORM_SETUP turn off the watchdog

9c2deb8e0a cntr/cntr.brd: remove the ground fill. The board got a bit messy with it. 
Bumped the version to V1.
