New mac range cisco smb

To "3.3.1 SP4 HF8".

Only a comment was changed between version 1.7 and 1.8, so let's do like
nothing has changed.

Update Yealink W52P handset firmware to 26.73.0.30

Add supports for the Patton SN4110 and SN4300 series.

Add it directly in the plugin since it's not available on the public
Snom server.

We could also put it on one of XiVO server, but it's simpler like that,
and the file size is only 878 KiB.

xivo-confd creates configs with these kind of labels, but xivo-provd
plugins expect the 'label' key to NOT be defined if the label is
unspecified, i.e. if a default label must be used.

This was a bit problematic on the D745, since when not specifying a
label, the phone was automatically creating a label from the
"fkey_value" value, and for BLF function keys, the generated label was
actually something like "1001|*8", which was quite ugly.

The plugin only supports the D745 currently and is a work in progress.

For xivo-yealink-v73 and xivo-yealink-v80 plugins only.

Deprecated in favor of xivo-cisco-sccp-9.4.

To use the latest one, which is the same as the one used by the
xivo-cisco-sccp-9.4 plugin.

For most models...

So that the documentation on the "minimum required version" of each
plugin is sane.

This is used by xivo-provd to prevent information leak from brute-force
attacks.

Deprecated in favor of xivo-polycom-5.4.3.

This is redundant with with the default config.
