footer.php minor fix (footnote.gif link removed)

New reboot system. It shows now a loading gif image without crashing
because of not accessing the WRS anymore.

- Reboot javascript function: displays image, message & reboots without
web crash
- Redirect javascript function: When rebooting, it redirects to index.hp
after 50s.
- All shell_exec("reboot") calls have been replaced by wrs_reboot() in
all files.
- loader.gif added
- new entry to style.css, one for the gif animation and other for the
text.
- reboot.php & rebooter.php carry out the new reboot.

This fix is needed by 7S-SCBv3.4-S2 because it mounts the old AT45DB642D. 
The patch is temporary because wrs_version will use dotconfig for next 
release. It is why we have an "ugly" but working parsing.

If the usb cable is disconnected, any write to /dev/ttyGS0 goes to a
buffer until it fills. Then, any further write will block. This means
the messages towards the user ("uncompressing filesystem... done" etc)
caused the update procedure to stop.

This fixes the problem by using non-blocking write for the messages:
if nobody`s reading the messages are just discarded by the kernel.

A "cleanup" commit in ppsi lost one step, and we were missing calibration
deltas. This fixes it

Without this, the upgrade procedure from v4.0 failed to preserve
the mac address. This fixes the bug which is explained here below.

What happened is that the new filesystem (v4.1) returns UNKNOWN as
fpga type, because no hwinfo is there.  This UNKNOWN should be turned
into the default type LX240T, so the fpga is programmed and everything
proceeds.

However, "UNKNOWN" is intermixed with the (expected) error message,
so no LX240T is selected and loading fpga fails.

Later, "ifconifg wr0" fails to retrieve the mac address, because no
WR drivers are running, and the generation of hwinfo fails as well.
As a result, after the second reboot (see user manual) there MAC
address for WR interfaces was not preserved.

It also delete temporary files

The output 9 => 10MHz output (CLK1), is disable until PLL is resync with
WR to force the output of two different switches to be in phase.

Standard JEDEC ID is only 24bits to identify a DF chip.
It also has an optional Extended Device Info (EDI) on bytes 4 and/or 5
that need to be read to differentiate some DF chips. (i.e, the
difference between AT45DB641E and AT45DB642D is made by byte 4).

This patch is similar to the kernel one #66595328
