This patch makes possible to tweak the downstream SNR margin on
Lantiq DSL devices.
The UCI parameter 'network.dsl.ds_snr_offset' is used to set the SNR
margin offset. It accepts values in range -50 to +50 in 0.1 dB units.
The SNR margin can thus be modified in range -5.0 to +5.0 dB in 0.1 dB
steps.
Currently this should only affect ADSL (not VDSL). It should be very
easy to make this work also on VDSL lines, but since I couldn't test
on VDSL lines this patch does not do that yet.
I have also a patch for LUCI about this, that I could submit.
Tested on FB3370 (Lantiq VR9) and Telecom Italia ADSL2+ line.

I do not know if this causes any problems now, but we should not set
it, because it is reserved. Some more recent versions of the Lantiq DSL
API driver and Control is checking if only valid bits are set.

There are some cases where ISPs are running ATM over VDSL or PTM over
ADSL, this is not the common case, but these cases exist. Make it
possible to configure OpenWrt for such cases by adding a new config
option line_mode.

The detailed annex option were only available in the danube DSL app
including the activation of G.992.2 Annex A (ADSL Lite). This is now
also added to the vdsl app for the vrx200.

I am not calling dsl_cmd because I want to ignore the lock, quit
should also be send when someone else is accessing it. I saw that some
other call was stuck here and all following calls were stuck in the
dsl_cmd lock.

Before r47933 Bit 1 (first bit) of xTSE Octet 1 (first octet) defaulted
to 1, which allowed T1.413 to operate.

Add back a slightly modified version of the lowlevel settings which
where removed with r46920.
In compare to the old lowlevel settings, the B43c tone is added to
tone_adsl_b and tone_adsl_bv.
If an unsupported tone value is used, the auto probing mode is used, in
compare to the fallback to tone_adsl_av and tone_vdsl_av with the old
lowlevel settings.

According to ITU-T G.997.1 Amendment 2 (04/2013) section 2.1, bit 3 of
XTSE octet 8 either allow or denies the initialization of G.993.5.
Even if the current redistributable xDSL firmware doesn't include
G.993.5 vectoring support, enable this bit by default to allow people to
get their G.993.5 line working using a custom xDSL firmware.

r47933 revealed that the driver/app in combination with the chosen
firmware does a good job in selecting a working xtse.
Use this probing mode if no annex is specified.

This patch adds the missing VDSL2 bits to the annex specific XTSE (like
it should be according to the comments above the XTSE bits).
Since r47933 it's mandatory to remove the annex option to switch to
VDSL2 (only) operation mode.
As shown by ticket #21436 and a few mails I received personally, even
experienced users are not aware that they have to remove the annex
option to get their VDSL2 line working and as shown by this patch it
doesn't need to be that "complicated".

Thanks to Sylwester Petela for testing my patch (successfully on an
ADSL connection) and for pointing out some configuration mistakes.
Others (including me) have also successfully tested this extensively
on VDSL connections.

I had to use a VDSL-only tone-setup to get show-time.
Handle this in uci by checking if annex is unset.
