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
division before multiplication.

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.

Meanwhile, this cleans up declaration of functions that were not prototypes
in wrsw_hal.

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)

Text was not fitting the box. It has been reduced by 1.

Adding new functions to get method used, salt and counter for the
different type of encryptation methods.
By this moment, the web interface encrypts using md5 with a random salt
by default.
Old method removed.

Updating password from the web interface now modifies dotconfig instead
of phpusers file.
For security reasons the web interface only saves the password
encrypted.

Login now uses the user and password from dotconfig instead of phpusers
in filesystem.
Now it is suposed to use same username and password for the shell and
the web interface.
Changes are also applicable for both of them.
Nowadays there is only one user: "root"

The apply_dot-config script was wrong: it wouldn't force on the
empty root password. Thus, if it is set to something non-empty
and then changed (by a network dot-config) to empty, it won't work.

This bug only revealed on nfs-root setups.

Now, it's stupid to keep two symbols (ROOT_PWD_CLEAR and ROOT_PWD_CYPHER),
and I could simplify the script. And re-test. And change docs. No thanks.

lm32-vuart was destroying the tty it was run into. And ctrl-C was
not working (the initial message "press ctrl-A" was not really
visible).

This removes part of the cruft of the program. It also adds a little
delay when no bytes are there to read from FPGA to releaf a little
the load on the ARM CPU.

I already fixed that, but likely I made an error in "git rebase -i" before

New CSS style for sfpcalibration.php and endpointcalibration.php and
management.php to make it fit in the layout for both Firefox and Chrome
for both Windows and Linux.

Blank spaces and lines have been removed.
Now in management.php users can modify DOT_CONFIG_URL
A warning message when uploading or adding URL dotconfig is now shown.

In case dotconfig file has been modified by other users, the web
interface shows an alert, reloads dotconfig and the data structure.

WR-PPSi now supports GrandMaster, Boundary Clock and FreeRunning modes
using dotconfig.
NTP server is now in PPSi configuration. When users try to set a NTP
server in BC mode, there is an alert message because of the WR timing
override.
Help messages have been changed for management.php and ptp.php because
of these changes.
When the user tries to save changes and dotconfig file was modified by
other user, the data structure must be reloaded (changes are not done)

WRS mode and NTP server will be part of WR-PPSi section.
