The conversion has been fixed now for negative values.

- New mechanism for clock degradation (degrade clock class, clock
accuracy, clock variance, timeSource, ptpTimeScale, frequencyTraceable,
timeTraceable)
- timeSource can be configured now
- If clock accuracy, clock variance and timeSource are not set in
ppsi.conf, default values are used depending of the clock class.

- Problem was coming from the interval to pico conversion when  the
interval is negative.
- fix also issue in wrs_ajust_in_progress

- Change the Quality structure to make it compliant with the standard
- Fix network to host conversion to display offsetScaledLogVariance

Modification made to be more coherent as delayCoefficient is in range [-1,1] instead of [-2,2].

- Take into account the rounding in time conversion
- New implementation of pp_time_hardwarize

- New L1Sync and PTP servo calculation (delayAsym,...)
- Make function calls more uniforms between extensions
- refactoring
- Add a new state machine to enable/disable an extension and provide
only PTP support: New timer, new hooks, ...
- Fix bug in time format conversion
- Code removed when an extension is not required (#ifdef XXX )
- Align the PTP and L1Sync servo calculation (shared fct, same
calculation,...)
- Force only one servo running at a given time for a given instance
- New servo reset hook : called by main loop
- Add function to converte a time into a string
- Force to stay in FAULTY state during 60s
- Optimise function wrs_enable_timing_output()

This new parameter is used to control the configurable parameter
L1SyncOptParamsPortDS.timestampsCorrectedTx when
L1SyncBasicPortDS.optParamsEnabled is set to true.

The delayCoefficient can be set in ppsi.conf file either with the
delayCoefficient (double) parameter or the scaledDelayCoefficient
(RelativeDifference)  parameter. In ppsi, the priority is given to the
scaledDelayCoefficient.

- Add new config parameters (l1SyncRxCoherencyIsRequired,...)
- Add new profile: CUSTOM. It will be mostly used for testing
- Fix issue on state name: "pre_master" instead of "pre-master"

In the ptp servo the adjustment of the time was too slow. When the
difference of the time with the master was less than 1 second, the
adjustment was done only with the frequency. In case if the difference
is 0.999s, it can take a very long time to adjust the time.
Changes made :
- Adjust with frequency only when time difference is below 20ms
- Check the timestamp validity before each calculation
- Create a new function to check the timestamps and use it on all
servos. This improve significantly the size of the code.
- Add verification in order not to set an invalid UNIX time

- This function checks now the minimum and maximum values which can be
encoded into a RelativeDifference type.
- Bux fix for the calculation of min/max value conversion (special
cases)

- Set the minimum and maximum values of some parameters
- Fix format issues in pp_printf and sscanf

- The %f format is not supported in pp_printf. So we will not display
the float value in error messages.
- Change DBL_MIN by -DBL_MAX to have the minimum value of a double

This implementation does not include yet the possibility to declare 2
exclusive instances on a same port (WR & HA)
- Some structures are renamed with the suffix _t to make it more
readable.
- Some variables are renamed  to be more clear
- Implementation of masterOnly, slaveOnly and externalPortConfiguration
- All extension specific includes (XX-api.h) is now automatically
included in ppsi.h and do not need to be included in other files.

- New  parameters added
- Parameter check with min/max values
- Updated fied mask suppressed: At startup the conf structure in each
ppsi instance must be initialized with the default values.

This arguement was used to set all ports to slave role. As it may be on
conflict with the ppsi configuration, this parameter has been
suppressed.

- We can declare now a list of keyword for the parameter name :
it make the declaration of keywords more compact in conf.c and use less
memory (eg. "extension profile" )
- We can declare also a list of keywords for the parameter value
(eg. "true 1 on" = 1)
- Add the possibility to mark parameters set in the config file. It is
very important to know in some cases in order to apply the default value
or not.
- Decode other parameter types: boolean, double

This implementation works on a WR Switch but does not yet integrate all
required functionalities. List of current modifications :
- Implementation of the L1SYNC protocol
- Modifications of the standard protocol: new hook, TS calculation
- Change WRS to integrate HA
- HAL adaptations
- ...

standard IEEE1588-2018

We bring here a lot of changes to :
- make the implementation more complaiant with the standard
IEEE1588-2018.
  We introduce new structures for the time (TimeInterval, Relative
difference)
  Named used in structures are aligned to the standard, ...
  It is just a first step. More work is needed
- be able to use more than one protocol extension at the same time
  (configurations, structures, ...)
- add the concept of profile
- increase diagnostics by displaying also standard PTP servo
informations

For wrpc-sw, this depends on a similar commit in wrpc-sw, because
arch-wrpc relies on that implementation (to avoid building two of them).

This is already in place for arch-unix, but is not working for arch-wrs
because we need to look for the interface name before opening it.

The idea that somebody wants to steer time for >1s offsets is
perverse.  Let's simplify (if any, we may want to jump for <1s offsets
that are bigger than a few milliseconds).

While it may make sense to setup constant delay somewhere (for WR we
define them, for instance), the legacy implementation was unused and
wrong.

Unused because nobody sets it (even if we could do it in the config
file).  Wrong because inbound is never used, and both are global and
not per-port.

Now this is the behaviour for the choice:

    arch-bare-*

         if you select P2P, it's built and selected. Default is E2E_ONLY.

    arch-sim
    arch-unix
    arch-wrs

         The P2P is built by default configuration, and the mechanism
         is selected at configuration time. Default is E2E. If you
         choose E2E_ONLY and configure pdelay, it will ignore the config.
         (Suboptimal but I'm lazy: do *not* use E2E_ONLY for those archs.

    arch-wrpc

        The default is e2e until changed at run time.

Here in ppsi,

  ./MAKEALL wrpc_defconfig wrpc_pdelay_defconfig

shows a very small difference, but most pdelay code is then
discarded by the wrpc-sw link time, due to --gc-sections.
This is the result:

   laptopo% ./MAKEALL spec_defconfig spec_pdelay_defconfig
