When the dot-config file is read at startup using the DHCP service to
get the server IP address, the script waits forever the availability of
DHCP service in the following case :
- CONFIG_DOTCONF_SOURCE_FORCE_DHCP=y AND CONFIG_ETH0_DHCP=y

CONFIG_ETH0_DHCP: Set to indicate that the network is forced to use DHCP
for its setup.

In the other cases, the behavior stay unchanged.

The parser must take care of the help text because it can contains
KConfig keywords.
So, this fix identifies help sections and does not parse the help text.

- ARB_GM correspond to clock class 13.
- Interface changed with assembly_ppsi_conf.sh :
   - The clock class number is always defined in dot-config.
assembly_ppsi_conf.sh uses it instead of the timing mode.
   - The PTP options (accuracy, variance, timeSource) can be overwritten
and KConfig proposes always the default ones depending of the timing
mode.

A minimum delay of 20s is applied to all port for the the RX
calibration. After a reboot, all ports will be UP at the same time if
the RX  calibration time is less than 20s.
The same mechanism is applied all the time the link is going up.

Disable the SFP TX before starting the TX calibration and enable it
again when all ports are TX calibrated

After a reboot, all ports a waiting few seconds to try to be UP at the
same time. This is done to avoid PPSi (BMCA) to change all the time its
port states

Dependency  on minirpc submodule has been removed and a folder minirpc
has been created to replace it with the original code. The git history
has not been kept.

With  the new version of HAL, rtud was exiting sometimes at startup
because it was not able to connect to the HAL's shared memory

This state has been added to avoid blocking the fsm too long. This was
the case with a sleep of 100ms. This value can now be increased without
influencing other ports.

- Export HAL generic fsm to libwr (based on Tom work)
- HAL bug fixes and state machines changes

This version of HAL works but need some improvements

In the state machine, returns to START state if the link is going down
in RESET_PCS state.

In the RX setup state machine, the earlyLinkUp timeout must be restarted
every time we enter in the START state for the first time.

The time-out was set before to 10ms to accelerate the TX and RX
calibration process. After making some measures, it appears that it does
affect the calibration time.

This new state is used by PPSi the end of the initialization of all
ports before starting to change the timing mode. This is particularly
the case for the GM mode which is set during the initialization of PPSi.

- HAL shared memory modified to hide and remove some dependencies not
needed by PPSi
- LPDC structures are now stored in HAL shared memory. They are then
accessible by the share memory dump tool
- Improve the initialization procedure

Tollerance replaced by tolerance.
