There was a problem with calculating fan timeout in libwr. Problem occurs when
there was a jump back in time. Since gettimeofday was used, delta for timeout
calculation became negative.
One solution was to use monotonic clock like in main function of HAL, or use
the same timeout calculations as main function. Second solution was chosen
since it is much simpler.

--remove calculation of fan/temperature read timeout in function
  shw_update_fans
--remove function shw_pwm_update_timeout and variable fan_update_timeout from
  libwr/fan.c as not needed anymore
--remove function shw_get_tics from libwr/util.c and libwr/util.h (not needed
  anymore)
--remove SHW_FAN_UPDATETO_DEFAULT from libwr/fan.h (not needed anymore)
--increase PORT_FAN_MS_PERIOD to 250ms (trade-off 200ms of port update and 500ms
  of temperatures update)
--remove increasing t1 in HAL;s main, since t1 was overwritten anyway by t2.

Don't overwrite dot-config's source info with ppsi.conf's source info.
If needed for SNMP other files should be used.

With release v4.2 we only have one valid user (root) to enter the www
configuration.
The "www root" user also shares the passwd with "ssh root" user.

The new Kconfig option allows dowloading ppsi.conf at boot time, from
TFTP or otherwise.  The filename in the URL can include IPADDR and/or
MACADDR, so the same configuration string can be used to set up a
batch of switches with different configurations.

This factorized configuration stuff out of wrap_rootfs into a build
target.  It also adds building and installing "conf" so to allow the
following commands in the target (in /wr/etc):

	  make config

	  make oldconfig     (likely after editing dot-config)

	  make defconfig

I'm unable to build menuconfig at this time, because of missing
symbols in the target's libncurses. I hope to fix this when we
bump buildroot up (thanks Adam for that!)

Otherwise "Received SNMP packet(s) from UDP" is written to file everytime the
agent is asked for the information - if we write to ramdisk, RAM becomes full
over the weekend.

Built from commit e38409d

We need it for some copper SFPs, e.g. Cisco MGBT1

We still need them if somebody want to synchronize a regular (non-WR) PTP
device.

For security reasons, php user sessions are destroyed after 10 minutes
of inactivity. After this period, users must login again.

wr_mon must be seriously audited, and turned back to be ptp-based
instead of hw-based (we may have two ptp ports on the same hw port).

Meanwhile, this adds the peer's MAC address and the PTP state for each
port in "up" state, if ptp is running there. It's not perfect, but
I find it  useful.

The link lenght is most often wrong, because of missing calibration,
coarse approximation of the diffraction ration and a huge integer

The "pahse tracking: ON" line was confusing.  It's only role is saying
if tracking has been disabled (by wr_mon itlsef, because a user typed
"t").  So the message is now absent unless tracking is forcibly disabled.

If you re-build after stuff has been added to Kconfig, the .config you
already have in place is wrong. This means the dot-config at runtime
will have missing items.

We thus force a silent "make oldconfig" at each build step, to ensure
user preverences are saved, but new options get the default value.

Endpoint mode was not correctly displayed in endpointmode.php and
endpointcalibration.php when dotconfig CONFIG_PORTXX_PARAMS did not
include the protocol column.
Now, the forms are correctly displayed with and without the protocol
column in dotconfig.
NOTE: we assume that the protocol column is there or not for all ports or for none of them. (not mixture)

By this moment, the web interface encrypts using md5 with a random salt
