t24p calibration finds the rising&falling edges in
dev/rxts_calibrator.c:rxts_calibration_update.  It then computes the
"transition" as (falling+rising)/2.  That is, ttrans points 25% past the
dangerous transition.  Now that value arrives in one of the three copies of
ptpd_netif_linearize_rx_timestamp (depending on build).  In this method
ttrans has +-1/4 period added to it to compute trip_lo and trip_hi.  The
intent as described by the comment (and common sense) is to avoid the rising
edge when the phase is within +-1/4 period.  Unfortunately, this code
assumes that ttrans IS the rising edge, when in fact it is the rising
edge+25%. Thus, the code ACTUALLY tests phase within 0-50%.

This fixes the previous commit, which prevented to build wrpc-sw with
CONFIG_PTP_NOPOSIX (silly me).

Tom's fix for helper PLL, in Slave mode it should use RX clock instead of REF clock.

Tom's fix for WR Switch makes ptracker much faster so that SPLL can handle all 18 ports.

Greg's commit to fix the t24p calibration broke that calibration
for devices using sdbfs. The EEPROM write method clobbered the
phase transition value.

These headers shadow system headers.
While they are necessary for building on the LM32, it breaks any
code that wants the other WR headers on a different architecture.

By moving these headers, we can pick whether to use them or not.

This is a bigger change than expected, as the width was defined
in two places. So I moved the definition in <wrc.h>, whence everybody
picks it.

The variable was used to mask a few diagnostic messages but was always
set to 1. Since such messages are actually few at this time, remove
the variable altogether.

The code, however, included a hardwired check for servo messages, used
by the ptp-noposix callers.  This commit preserves the behaviour while
removing the dependency from ptp-noposix headers.  The result is ugly
but temporary, because we are going to phase out ptp-noposix.

Help commands are added at the top, irrelevant ones at the bottom.
This also removes the footnotes, by moving the note inline (rationale:
in the longer list they would fall in the next page).
