- Make externalPortConfiguration compliant with the PTP specifications
- Optimize code for externalPortConfiguration
- Optimize code for slaveOnly
- Replace "CONFIG_HAS_P2P && ppi->delayMechanism==P2P" by an inline
function

. Better integrate of code optimization with PPSi Kconfig
. PPSi Kconfig changes to simplify the code in PPSi and avoid #ifdef ..
. Improve code optimization
. Move some declaration in ppsi.h in other files to ligthen ppsi.h
. Improvement of timers: global or instance dependent, dyn. allocation,
renaming for better diagnostics, disabling allowed, ...
. New behaviour for the PPS output generation (configurable,...)
. Move control of the timing mode from HAL to PPSi
. Optimization of code when a Protocol extension is not available
. BMCA: Calculate the ebest,... only one time and then trigger all
instances to execute the bmca state descision
. Fix bug in the calculation of the clockIdentity to bring it into
compliance with PTP spec 2008 document
. Fix a bug related to Announce message received in SLAVE/UNCALIB
. WR ext: use dynamic timer and adapt to new PPS generation
. HA ext: Fix bug in fault injection mechanism

The custom profile is usefull for the White Rabbit switch integration
tests. It is now possible to remove it for other targets where the
memory space is critical (nodes)

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).

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.

There is a size problem in wrpc-sw, when built with SNMP inside, so
some users, notably CERN, want to avoid the pdelay code (allegedly 7kB
in the binary).

Users who need pdelay don't actually run SNMP, so they don't have the
size problem.  This new setup allows a wrpc-sw without pdelay-related
code.  Wrpc with both mechanisms built in will be run-time configurable.

the wrs and unix configurations for peer delay are removed, because
for those architecture the choice is going to be performed at run time,
in the configuration file.

Please note that this commit is config-only, no code yet is there.

This was a trial of mine, but it really has never been working (at least
on wrs -- I think nobody ever tried a non-wr code base on wrpc).

Too much of the timetamping, servo, pll, is dependent on WR being
available, this academic idea doesn't make much sense, so let's remove
a number of conditionals (and associated potential bugs).

Kconfig is updated with new arch.
It compiles but it's actually doing nothing

This adds the needed configuration items: architectures, extension,
cross_compile and wrpc_root.  So, what we passed on environment and
command line is now in the configuration file.

This changes the priorities of such options, so the Makefile is
changed to force $(CC), $(LD) and $(CROSS_COMPILE) down to subprojects
(i.e. pp_printf and arch-wrs/mini-rpc).  Also, we need to remove
quotes from .config items, and this is ugly linesin ./Makefile

Now Kconfig works, but we have no active configuration at all.
