This commit adds a tool to send out, through ethernet, a complete log of
DAC values for the main oscillator. It allows to see if there are
oscillations (and there currently are) and what happens when tracking
is lost and recovered.

To activate the feature

  * add CONFIG_DAC_LOG (depends on CONFIG_DEVELOPER)

  * activate on the console: "daclog <ipaddr> <macaddr>"

  * collect data on your target host

     netcat -u -l -p 1050  | od -An -t u2 -v -w2 --endian=big > daclog.txt

  * stop it when done, on the console: "daclog off"

Under frame loss, most track-lost are just because of ptp timeouts.
But since the underlying pll is unaffected, and the RTT is almost constant,
we can tell in the logs whether the lost/resync was actually a time
jump or not.

This is what happens with moderate frame loss (fhe first track-lost is
real, due to a ptp restart, the following ones are not and max delta
between calculated setpoint and current setpoint is reported):

This is my own fault introduced here:

   765443c7 udp: bugfix for checksum generation

It made no harm, because all send frames were oversized, but I'm now
using fixed-size buffers, and this overwrites the own IP address
thus corrupting the checksum and so on.

Pity me.
