It does not make sense when the init is stored in flash and the board has no
EEPROM. Otherwise, storage_init() calls mi2c_devprobe() if needed.

Also don't restart ppsi after SFP updates in the flash.

When snmpset is performed on not existing or read only OID, then response
packet does not contain to-be-set value. Due to that, returning packet is
shorter. It is necessary to recalculate sizes of the fields inside the response
packet.

We revert this commit, since we decided to support objects only from our own

So, revert the commit:

Requests produced by net-snmp's snmpget and snmpgetnext usually contains
4 byte request ID, but sometimes it is only 3 bytes.
When request ID is below 2^24 sometimes it is send as 3 bytes, sometimes as
4 byte value.

Split the OIDs into limb and twig parts.
Twig part can be interpreted as a groups or a table.
For each limb (group or table) there is an array with twigs (OIDs within group
or table).
When the limb part is matched, then the group or table function is called for
the twigs part.

Additionally:
--Add the table with temperatures (wrpcTemperatureTable). Any number of
  sensors is supported.
--Add wrpcTemperatureTable to the MIB
--print_oid_verbose can now print parts of OIDs

Possible to read/write:
-- wrpcPtpConfigApply
-- wrpcPtpConfigDeltaTx
-- wrpcPtpConfigDeltaRx
-- wrpcPtpConfigAlpha
-- wrpcPtpConfigSfpPn

setting a value writeToMemoryCurrentSfp to the wrpcPtpConfigApply will update sfp info in memory.
For now it is necessary to restart ptp to reload new sfp information.
