Firmware (and documentation) for the D765 has not been released yet.
Once this get released, will be able to complete the support for the
D765, i.e.:

* removing the "update_policy" to "settings_only" for the D765
  (otherwise an error messages is displayed and the phone doesn't
  continue its booting sequence)
* adding the D765 to the description (plugin-info)
* adding the D765 in xivo documentation

The D765 on which I did some tests had its firmware in version 8.7.5.21.

So that both the name (e.g. John Doe) and number (e.g. 1002) are shown
on the screen. Applicable to the 6867i and 6869i only.

So if a config ask for a BLF on a softkey, transform it into a
speeddial.

Refactor the current function key generation system to be able to
support all the different expansion modules.

This was used when there was a xivo-aastra-2.6.x plugin.

Replaced by the xivo-aastra-4.1.0 plugin.

The "language N" option for the 4.1.0 firmware doesn't behave the same
as for the 3.3.1 firmware. The 4.1.0 firmware tries to look for the
language files from the "root" of the HTTP server (e.g.
http://example.org/), instead of trying to look from the URL sent by the
DHCP server (i.e. http://example.org/Aastra).

To me, it looks like a bug from Aastra.

Don't put default softkey, except for a directory softkey, if none is
available.

To add reference to Mitel.

Remove duplicated code and a bit of dead code.

The xivo-yealink-v70 plugins references only the models for which there
is no newer firmware available, i.e. only the T32G, T38G and VP530P.
This is similar to the xivo-yealink-v72 plugin.

The xivo-yealink-v72 plugins references only the models for which there
is no newer firmware available, i.e. only the T19P and T21P. This is
similar to the xivo-yealink-v73 plugin.

The xivo-yealink-25.73.0.20 plugin is replaced by the xivo-yealink-v73
plugin.

The xivo-yealink-2015-03 plugin is replaced by
* the xivo-yealink-v80 (for T4X)
* the xivo-yealink-v73 (for most T2X and the W52P)
* the xivo-yealink-72.0 (for T19P and T21P)
* the xivo-yealink-70.0 (for T3X)

Forgot to put version in description.

As much as possible.

Since they have a few difference and it might be the easiest way to
manage the templates.
