/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.

In some rare cases it can happen that locally stored dot-config is not valid.
For example, when firmware on the switch was updated, but the old dot-config is
still used. However, such scenario is unlikely because new firmware should
contain new dot-config.

--Replace "." with "source" when sourcing 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.

Change done due to uplift of the buildroot to the 2016.02
Please note that some of the options just changed their position.

Some changes:

remove:
--DOS2UNIX
--UNIX2DOS
--FDFORMAT (we don't have floppy)
--EJECT (we don't have CD/DVD)
--HDPARM (we don't have ATA drives)
--ETHER_WAKE (to send wake-on-lan magic packet)
--DNSD (we don't need DNS server)
--NAMEIF (we don't want to change names of interfaces)

remove the following, since they're provided by prosps_ng:
--pidof
--top
--uptime
--free
--kill*
--ps
--sysctl
--watch

add:
--LFS (large file support)
--MD5_SMALL=0 (We don't care so much about the size, more about
  the performance. Use the fastest. Difference in the size is very
  small anyway.)
--SHA3_SMALL=0 (like above)
--CONFIG_GZIP_FAST=2 (like above, use the fastest)
--FEATURE_LESS_WINCH and FEATURE_LESS_ASK_TERMINAL allow to display i.e.
  "less" command via serial terminal with non standard terminal sizes.

Instead of keeping the list of archives in build/download-info which should be
downloaded for buildroot, we use "make source" to do the same job.
However, the task of building buildroot had to split into 3 tasks:
--init (unpack and configure buildroot)
--download (download the source of used buildroot packages)
--build (compile buildroot packages, etc.)

The reason for this change is to avoid updating the download-info file when
buildroot package is updated. Additionally ltrace is not downloaded as an
archive, but it is cloned git repo. After the clone it is packed into archive.
In the current state our framework cannot do the same.

make 3.82 splits the work differently. When using buildroot with
the make > 3.81 buildroot uses BR2_JLEVEL= (preferably 0 for automatic number
of jobs setting).
For make =< 3.81 BR2_JLEVEL= is ignored and build is done using only one job.
Passing -j allows to build with many jobs, but many warning messages are
printed:
make[2]: warning: -jN forced in submake: disabling jobserver mode.

Use BR_JLEVEL=0, this allows buildroot to pick automatically number of jobs.

Change the names of interfaces from wr0..wr17 (wrX) to wri1..wri18 (wriX).
Such change was done to avoid confusion that ports on the front panel are
numbered from 1 to 18, while in software they were numbered from 0 to 17.
Inconsistency started to show up especially in messages produced by software
causing confusion.

Be aware that even after these changes some software internally uses indexing
or ports from 0 to 17.
