Fixes: 4249d65a ("treewide: fix luacheck warnings")

This allows the script to be minified as well as being checked by
luacheck.

The logic is based on the previously used shell script implementation.

/etc/config/gluon-simple-tc was removed with Gluon 2016.1.

We now keep the VPN enable state, bandwidth limit enable and actual limits
in the core config to avoid having to recover "user intent" from different
config files when the used VPN packages change.

Fixes #1736

None of our scripts can handle fastd and tunneldigger running at the same
time. When both are installed, ignore tunneldigger.

./gluon-wan:25:1: (W122) setting read-only field ? of global arg
./gluon-wan:29:1: (W311) value assigned to variable ok is unused

None of our code uses cookies, so this issue went unnoticed.

The old bash-based parsing code was way too complex. Replace it with Lua.

It seems this mistake didn't cause an error because of Lua's support for
shebang lines.

Several fixes and enhancements related to multicast were added upstream
in batman-adv. So let's give the batman-adv multicast optimizations
another go.

uc is used in the initscript. It must be set as dependency

This commit fixes a bug where on first setup, mesh interfaces won't be
created for 2.4GHz radios.

The is_outdoor function is placed inside the gluon.platform module, not
the platform_info module. Currently, the outdoor-mode wizard component
and the upgrade script fail due to nil-value calls.

adds a section to the wizard for outdoor capable devices
that informs the user of of the regulatory situation and
allows a quick toggle of the outdoor mode.

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.

Fixes #1659

Fixes #1701

inet_pton() doesn't set errno on regular parse errors, so using perror()
doesn't make sense (and we avoid a confusing "Success" message).

The batctl v2013.4 build was removed from the batman-adv-legacy package
as the current, upstream batctl releases work with batman-adv-legacy,
too.

As a replacement we need to add the upstream batctl dependency to
gluon-mesh-batman-adv-14 to have a batctl available again here.
