kernel has two bugs regarding leap second handling: it need to have the
leap second flags cleared twice before setting them and it doesn't clear the leap second flags after the leap second happened. A workaround was implemented
accordingly.

Also in the loop for erbest the search was fixed if the first port
which is elected as ebest by default is not valid.

Since the portnumber is a 16bit value, memcp is not given to be correct
on all architectures depending on the endines

msg: reset ext_specific flags in the announce to zero when either no TLV is appended or the TLV is not a WR TLV

The flags was not set to any value when no TLV was appended or a wrong TLV was appended, in that
case the RAM content was wrongly propagated as WR flags which may caused that a node is going into
a wrong state.

For the dataset comparisment all known foreign masters have to be qualified
so the worst is found. Once aged out it will be removed so the qualification is
not relevant in this check.

The UTC leap flags are propagated to the system (unix) so the leap second is correctly handled at midnight
so the UTC time is always correct.

the variance is now set according to the servo state, the source and timescale
are set according to the clock classes set

Added clock accuracy constants and aligned the chaning of the clock class
with the accuracy

The clock class is now decreased and increased based on the servo state,
this only has an effect for wrs and wrpc since the contain a servo loop.

For links longer than ~13km, a value (uint32_t) returned from a function
__div64_32 shifted by 16 bits overflowed, introducing PPS offset.

For whatever reason we perform a normalization on an incorrect timestamp,
don't treat is as an negative value.

The clock class goes only to 6 if realy in gm mode, so not even passive
The variance was changed back to 0x8000 until computed

We don't compute the variance so the default value shall be 0xFFFF

bmc & default dataset: Handle passive for loopbacke frames correctly, take Clockid only from MAC of Port1

The switsch was getting the Clockid for the default datset for each port which has a different MAC on each port, this is wrong, now the Clockid is always fetched only from Port1 for all other ports.

Leap seconds are now also fetched from the system in case we are a grandmaster
A reset of the locking procedure was added so a locked switch can get master again

The audit portings changed the timely behaviour of the ppsi which cause wrong behaviours,
the timeout scheme was changed to only reset timeouts where needed and in all non PTP
states. UTC offset is now fetched from the system where supported, link up/down is now
considered in the BMC, also some state changes where cleaned up to be out of the BMC, e.g.
state changes based on timeouts between PreMaster and Master or between Uncalibrated and Slave.

Passive handling is actualy done differently, its integrated into
the bmc as a precheck.

Most of them were already ported, added a check before returning next delay if
a timeout for a (p)delay request has to be taken into account

Now everywhere the packet buffer is a void *buf and the lenght is int len

Only the patches ragrding the flag from the current master was
taken over, the other falgs are still needed and used.
