This adds config option to specify static roles for master and slave
in the Best Master Clock Algorithm. This is the case for Automotive
Profile where networks are mostly static and role for each device is
known in advance.
masterOnly and slaveOnly will be used to determine the roles for the
devices. Since masterOnly is a per-port config and slaveOnly is a global
config option, role assignment will be slightly odd in case of bridges.
If slaveOnly is set to 1, all the ports will be in slave roles except
for the ones where masterOnly is set to 1. These ports will assume the
master role.
Two new FSMs which will be used for master and slave roles for this
config option have also been added.

If set to 'true', this unconditionally sets the asCapable variable. The
usual checks will be applied to asCapable if it is set to 'auto'. The
default value is 'auto'.
This config option is needed by the Automotive Profile. The master will
be able to send out Sync Message as soon as the daemon is started.

Add attribute maxStepsRemoved which is included in IEEE1588-2017 (v2.1)
It is an optional attribute which can decide if an Announce message is
considered in the operation of the BMCA or not.

The sub agent use net-snmp library and AgentX protocol for the
communication towards the snmp master agent.
snmpd.c should only include general setup needed for handling snmp.
Supported MIBs should be implemented in separate files.
Makefile will include snmpd if libsnmp is available during compilation.
configs/snmpd.conf should be placed in /etc/snmp/

The default initial value for logAnnounceInterval should be 0 (once per second).
See chapter 10.6.2.2 of IEEE 802.1AS standard.

This patch adds configuration file support for a table of unicast
masters. Each table lives in its own section and has a unique,
positive numerical ID. Entries in the table are a pair of transport
type and protocol address.
Each port may specify a table id to be used for unicast negotiation.
Tables may not be shared between ports, but nothing prevents table
entries from appearing in more than table.
