When the extension is inactive due to some circonstances, an instance
will reactivate the extension when the instance will jump to
UNCALIBRATED state.

In the previous code all these values where hardcoded and thus difficult
to port to a device similar to wrs without needing to fully rewrite the
wrs-time.c. With this new code the user can now modify the device to
access to FPGA and the offset of RT subsystem.

Also ignore generated size_wrs_info.txt

For security we still use define in the case that the hal as not
properly set these value.

When the link state changes rapidly, it can't be detected by PPSi. This
is the case with the BTrain configuration. So we must detect that the
peer has changed and restart the servo for a slave and use the right
protocol (extension/ptp).

The structure was not updated when the FAULT timer was removed.

At startup the state of a instance is set to DISABLED and will be set
if the link is up to INITIALIZING. This is done to be coherent with the
curent behavior: the state becomes DISABLED when the link is down

The WR time is set in GM mode as follow :
1/ At startup the NTP time is set using wr_date script
2/ PPSi calls the tool wr_date with parameters "set host". It will be
called every time it detects a PLL transition from UNLOCKED to LOCKED
state. Also PPSi provide a error counter 'gmUnlockErr' which gives the
number of time the PLL unlocked.
3/ Parameters "-v set host" in wr_date tool, set only the second part of
the WR time. The time is set in a middle of two WR seconds ticks.

- Give priority to the time-out and not the number of msg repetitions
- Call also wr_handshake_fail() function when a time-out is detected.

As the enable_output_timing() hook  is called also in the standard PTP
part, the hook has been moved from the WR specific structure
wrh_operations to  pp_time_operations

- Add a new state machine available for all timing modes ( Free running
master, Grand master and boundary clock)
- State is stored in pp_globals, field timingModeLockingState
- The 3 main states are :
-- Locking: Waiting for PLL locked
-- Locked: PLL is locked
-- Error: PLL is unlocked but was locked before
- Changing the timing mode will reset the state to 'Locking'

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

- Calculations made using fixed pointarythmetic
- delayAsymCoeff calculated using polynomial expansion
- Based on Rens Roosenstein work

If a PLL unlocked is detected on slave side  when the servo is running,
the PTP state is forced to UNCALIBRATED to restart the WR calibration
(handshake)

- Simplify how an instance switch from WR to PTP protocol and vice-versa
- Change the WR state machine: When an unexpected WR signaling message
is received, the state is forced to IDLE. Solve handshake issue when
instance is waiting for an answer with a long time-out and in the other
side the PPSi process is restarted. In this use case the handshake will
fail.

The logic used to control WR switch leds is removed from HAL and
imported into PPSi. It prevents HAL from reading PPSi shared memory.

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

This is a temporary implementation that will be reviewed when the PPSi
live configuration will be implemented.

add monitor variable to struct hal_port_state

Will be reintroduced later with HA profile.

- Code optimization for size
- HA is not compiled ( only PTP & WR )
- ...

See commit 'Simplify WRS calibration functions' below

- Has Hal is no longer used for ingress/egress latencies, we must then
take them from the configuration file
- Definition used by the common servo (WR & HA)
- Implementation of the IDLE state
