Hal creates shmem before waiting for SoftPLL to lock. By this other programs
waiting for HAL's shmem can start.
Please note that after this fix PPSi does not create shmem before lock.
It waits for HALs minipc server to be ready.

Before shmem is created, read hal mode first.

Add a script to gather data via SNMP in the given interval, store it a file
and draw a graph.

Example use:
./snmp_graph.sh -f oids_temp_ip.txt --ip 192.168.1.10
./snmp_graph.sh -f oids_temp.txt --ip 192.168.1.12 --mibs-path "/var/lib/mibs/ietf:../snmpd" --mibs-load WR-SWITCH-MIB"

snmp_set_var_typed_value function does not epxect counter64 values as a
uint64_t, but as a struct counter64. Their binary representation differs by
order of 32bit words. By this it was wrongly seen as a endianess problem.
Since some status objects use 64bit values for calculations it is more
convenient to use uint64_t in our structures, then convert to struct counter64
just before passing data to the SNMP engine.

There was a special case when there was no update of pstats, but status was
recalculated. Since counters were not updated then deltas of counters were
within limits. It could happen that counters are growing, but statuses are
returning "ok".

For example problem was in the case, when object wrsPstatsHCRXDropRTUFull.1 was
increasing at every read:
$ snmpget WR-SWITCH-MIB::wrsPortStatusSfpError.1 # this triggers a read of
status ports
$ sleep 2
WR-SWITCH-MIB::wrsPortStatusSfpError.1 = INTEGER: sfpOk(1)
$ snmpget WR-SWITCH-MIB::wrsRTUStatus.0 # triggers only read of pstats, values
of status ports are cached (only 2 seconds elapsed)
WR-SWITCH-MIB::wrsRTUStatus.0 = INTEGER: error(2)
$ sleep 4
$ snmpget WR-SWITCH-MIB::wrsRTUStatus.0 # pstats value are cached, but deltas
are re-calculated and are equal to 0. This sould report error as well.
WR-SWITCH-MIB::wrsRTUStatus.0 = INTEGER: ok(1)
After the code is fixed the last one returns error(2)

/etc/init.d/dot-config can save information e.g. that it failed to get
dot-config form the given URL. However, apply_dot-config called from
/etc/init.d/dot-config overwrites this information by the result of checking
the dot-config. The checking of the dot-config has to be done also in
apply_dot-config, because the webinterface writes down changed dot-config and
executes only apply_dot-config.

For example, when firmware on the switch was updated, but the old dot-config is

contain new dot-config.

Perform uplift of the buildroot to the 2016.02.

Signed-off-by: Adam Wujek <adam.wujek@cern.ch>

When switch's firmware with buildroot older than 2016.02 was updated via
copying wrs-firmware.tar with buildroot at least 2016.02 to the
/update partition, then hwinfo in the flash was overwriten.
Such behaviour was caused by crashing during execution of /wr/bin/sdb-read.
Crashing sdb-read caused the following if's condition from the file
/etc/init.d/hwinfo to be false.

if /wr/bin/sdb-read /dev/mtd5ro > /dev/null; then

This triggered later overwrite of hwinfo partition.

/wr/bin/sdb-read was crashing because during update the binary /wr/bin/sdb-read
was called from just extracted firmware. Problem pops up when libraries
required by sdb-read are in the different versions in the old and the new
firmware. Unfortunatelly, this problem cannot be easily solved, since we cannot
change the update procedure in already installed firmware (the one that is
performing update).

Implemented solution does the following:
--change the name of /wr/etc/sdb-for-dataflash to /wr/etc/sdb-for-dataflash.bin
  by this /etc/init.d/hwinfo script exits with an error without modification
  to the hwinfo partition.
--rename link /etc/rcS/S90hwinfo to /etc/rcS/S10hwinfo, which will trigger
  update of hwinfo partition earlier during the boot.
--restart switch after update of hwinfo in the flash
--remove calls of /etc/init.d/hwinfo during the update

The problem is that the "reboot" command sends the signal to the init. However,
it looks like init queues all incoming signals. They're handled after all
"sysinit" commands from the inittab are finished.
reboot -f skip sending the signal and triggers the reboot immediately.

This problem pop up after update of a buildroot to version 2016.02.
