When snmpd's init script is called with restart option then script complain
that snmp is already running. Probalby it takes some short time to kill snmp.
Add sleep 1 second to solve this problem.

There was a problem with counting multiple instaces of a program especially
for dropbear where new instance is spawned for each ssh session.
It is impossible to predict number of instances at compile time or even in
run time. What we know is that at least one dropbear process should be running.

New method is capable of reporting when there are too many or too few processes
running (exp value is positive)or reporting when too few processes are running
(exp value is negative).

Use full path for snmpd binary.

snmp tried to read file with hostname and filename of dotconfig source.
Such files exists only when dotconfig is retrived from network.

wrsConfigSourceFilename when config is local.

Improve getting scb version in boot scripts

Use wrs_version -s in /wr/sbin/startup-mb.sh to get scb version.

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.
