Include the file-extension with the image-customization.lua file. This
will ease work with editors providing syntax highlighting, as they now
properly detect the file-type.

Now we use the new Image-customization framework in Gluon, we need to
also update the docs so examples and descriptions are acurate again.

Implement a flexible system for handling site-defined features as well
as packages.

This system is inspired by the existing feature-system and allows for a
more flexible approach for selecting specific packages for devices.

Features are now defined in a `features` file in the site-root. The same
goes for packages.

These files are sequentially evaluated and the device-package list is
evaluated for each device independently.

We currently don't have any deprecated devices, so it doesn't make much
sense to force every site to specify this variable. Make it default to 0
instead.

Fixes #1775

This new build flag is mandatory for now (it may default to 0 in a future
Gluon version). It may be set to the following values:

* 0 - Do not build any images for deprecated devices.
* upgrade - Only build sysupgrade images for deprecated devices.
* full - Build both sysupgrade and factory images for deprecated devices.

"Other" images are handled like factory images, as they are also used for
the initial installation of Gluon on a device.

Add the `wifi5.outdoor_chanlist` site configuration that
allows specifying an outdoor channel range that can be
switched to for regulatory compliance.

Upon enabling the outdoor option the device will
 - configure the `outdoor_chanlist` on all 5 GHz radios
 - which may enable DFS/TPC, based on the regulatory domain
 - disable ibss/mesh on the 5 GHz radio, as DFS *will*
   break mesh connections
 - allow for htmode reconfiguration on 5 GHz radios

The outdoor option can be toggled from
 - Advanced Settings
   - W-LAN
     - Outdoor Installation

The `preserve_channel` flag overrules the outdoor channel
selection.
