Move reading of temperature sensors' tresholds from hal to snmp. Thresholds
were and still are read from dot-config.

update:
--hal
--hal_shmem header
--snmpd
--wr_mon
--wrs_dump_shmem
--uplift ppsi (update hal_shmem header)

When hal crash, monit will trigger rtud and ppsi to restart.

Split start-daemons.sh.in into init scripts for:
--HAL
--RTUd
--PPSI
Since HAL, RTUd, PPSI have already waiting for dependent processess
implemented, we're allowed to spawn them (semi) simultaneously.

Additionally:
--Remove start-daemons.sh.in
--Remove updating start-daemons.sh.in log values in apply_dot-config
--Create links in /etc/rcS/ to init scripts

NOTE: Be sure that no init script has the same name as running program.
      It may cause problems for "pidof".

Improve getting scb version in boot scripts

Use wrs_version -s in /wr/sbin/startup-mb.sh to get scb version.
Previous method to distinguish scb versions did not work in all cases:
mtdinfo -a | grep -A 1 dataflash | grep 264
Signed-off-by: Adam Wujek <adam.wujek@cern.ch>

This parameter will be used by /wr/sbin/startup-mb.sh script to pass scb
version to lm32 loader. "-t" parameter cannot be used here because lm32 loader
expect version number to be without dots. It is shorter, better, faster, more
elegant to put extra parameter "-s" instead of using e.g. sed to parse "-t"
output.

Sometimes we want to print message with high priority without indication that
it is error. This is workaround for this problem.
For example report program's version.

This allows, among other things, to see big jumps happening (if we are
slave and the master jumped in time due to user interaction: this is "only"
useful during developement, i.e. it *very* useful during development).

Make rtud and rtu_stat to be able to start in parallel with hal and ppsi.
(wait for hal in rtud, wait for hal and rtud in stu_stat)
Signed-off-by: Adam Wujek <adam.wujek@cern.ch>

Since rtud and rtu_stat wait internally for hal and rtud shmem to be available,
there is no need to check that in startup script. For the same reason we can
remove "sleep 4" before calling rtu_stat.

Also there is no need to check whether ppsi binary is available. Such situation
will be reported in different ways.
Signed-off-by: Adam Wujek <adam.wujek@cern.ch>

rtu_stat has to wait for hal and rtud to be ready.
It waits for hal's shmem and rtud's minipc connection. There is no need to
wait for rtud's shmem since it is initialized before ipc server is available.

Additionally few minor changes in printouts.

It may take few seconds to start hal, rtud shouln't complain about it during
5 seconds.
Additionally change fprintf into pr_error.

Sometimes it happens at boot that rts_get_state fails. It may be due to race
condition with ppsi or something else. Anyway try again when rts_get_state
fails.
Additionally print message when got timeout from tmo_expired.
