SNMP checkes whether monitored daemons where restarted by looking
at the respective /tmp/start_cnt_X file. Such file is not created
if a daemon is disabled in configuration (dotconfig). Such
disabling is a new feature. It turns out that not all of SNMP
deamon was updated to accommodate it. The SNMP daemon was checking
at start which daemons are disbled but later did not use this
info in wrsStartCntGroup and the startCnt of the disabled deamons
was attempted to be checked, resulting in an error. This has
been fixed.

As monit process is started after other processes, it does not take into
account  the 'unmonitor' messages sent from start scripts (ldap.sh,
...). This generates error messages at startup.

To avoid that, the configuration of monit is set now dynamically in the
apply_dotconfig script. All disabled processes are then removed from the
configuration to avoid errors due to process start order.
Also the first monitoring cycle is postponed by 30s at startup.

If dot-config is read remotly using DHCP for the URL, the host name in
the URL is not well substitute.
The fix forces the update of "hostname" when the script
dhcp_get_filename.sh is called.

The problem was as follows:
- there were two nodes with the same MAC address, sending traffic
  at high frequency
- the above triggers a lot of learning requests to rtud, as a result
- rtu HASH table representation in SHMEM is constantly udpated
- the aging process runs in background (separate process) and updates
  the time the entry was last used.

The update process could not the time of last access in the HASH
table in SHMEM because the learing process was constantly occupying
the SHMEM. The age out process was never aging out entry (even if this
one is within mutex) since the access time was never updated.

Thus, now both, update of last access time and age-out process are
both within mutex that allows the learning and aging-out processes
to both access SHMEM and HW.

When using wrsw_vlans to update config, by default, display which
config has been updated and which has not been updated.

Do not display updates when reading from file or explicitely
requested to be silent with "-q" option.

Related to issue #202

There were few bug/problems:
1) Setting of tag/untag worked only when enabling tagging,
   if tagging was later set to disabled, this did not take effect.
2) This affected default configuration of tag/untag function
   when qmode of port was set. Thus, when changing to TRUNK
   from ACCESS, the port would keep untagging

The value of temperature that is read from register of the T100
sensor is encoded with twos complement on 16 bits. The encoding
was not proper thus it worked fine but only for positive values
of temperature. Added function that properly interprets the
value of temp read from sensor's regsister.

Bug fix for PPS generation

Fix display errors for diagnostics

If it is disabled, it's commented out in dot-config, if it is enabled,
it appears with "=y"

The fields in this table were not really filled in after
substantial changes to the PPSi architecture regarding
servo (HA-related). Filling in of the fields in this
table had to be redone. This commit fixes filling in
most of the fields that were field before. There are still
some fields that are not filled in, tbd.

Move wrsPtpInstanceName to be the first (after indexes) OID.
Thanks to this, by doing snmpwalk/snmpgetnext of OID wrsPtpInstanceName(.<n>.<m>),
the user gets in a single responce:
--n - a port number
--m - an instance nubmer
--value which is an instance name
