mesh-vpn: fully abstract VPN methods

This fully abstracts VPN methods, making gluon-mesh-vpn-fastd and
gluon-mesh-vpn-tunneldigger completely self-contained.

Provide a LUA interface for generic interacting with VPN methods in
gluon-mesh-vpn-core and web packages.

This also adds the ability to install tunneldigger and fastd to the same
image, selecting the VPN method based on the selected domain.

Simplify save/commit handling of config wizard sections

A missing uci save for gluon-setup-mode caused the initial setup-process
to be stuck in a config-mode loop.

Simplify the individual form providers by always running reconfigure. This
also commits all UCI packages, so we can remove all tracking of UCI
sections from the wizard code.

Instead of returning a list of packages to commit, the providers just
save their settings directly. Explicit runs of upgrade scripts are
removed, as they are now run by reconfigure.

This add support for a write() method on sections, in addition to the
value and form level write(). write() is only called when the section is
valid and visible. In addition, write() is empty by default, so it can be
overridden more easily.

according to the paths they touch.

a883e3af38 dropbear: Fix CVE-2020-36254

This is a preparation to use the gluon_wired.sh proto on top of
layer 3 tunnel interfaces.

Before this commit the decision whether a vxlan layer will be
introduced between the lower interface before the interface is
added to batman was inside the proto. Now the decision is moved
to the user of the proto.

gluon-web-private-wifi: define ifname for WAN radio

08ef2073d4 ramips: backport unlocked mdiobus accessors

Add a package for handling upgrade-scripts speific for the WAN radio
operation.

This way, the config mode interface can be removed seperately from the
core functionality to perform tasks on system upgrade. This can be
useful when the setup-mode is removed entirely for space preservation.

mesh-wireless-sae: drop unused function parameters

Drop these unused parameters in the function description, as only the
first parameter is referenced within the function block.

Set the ifname for the WAN radio (Private WLAN) to wanX, X being the
radio index.

All other radios created by Gluon already have their ifname defined
following this pattern.

actions: build gluon for next sub-branches

Currently we do not perform CI firmware builds on the next-2102 branch.

Build Gluon for all branches starting with "next" to increase the
coverage of our build tests.

web-admin: fix firmware partition name

The rudimentary flash size determination function expects the partition
for the devices firmware to be called "linux" while it is (since quite
some time) "firmware".

Fix this error to display available flash size as well as more useful
error message in case the uploaded firmware image exceeds the flash
space.

gluon-mesh-batman-adv: reenable batman-adv multicast optimizations

With batman-adv 2020.4 and the according backports to batman-adv v2019.2
several more bugs were found and fixed regarding the batman-adv
multicast optimizations feature.

Also a "wakeup-call" feature was added to the Linux bridge IGMP/MLD
snooping code in Gluon to work around issues with Android devices.

With batman-adv now at v2019.2, multicast-to-multi-unicasts conversion
is supported, too. Which means that even if there are a few outdated nodes
these and all other recipients will be served multicast packets via unicast,
too, as long as the sum of receiving nodes does not exceed the multicast
fanout setting (default: 16). If is exceeded, then batman-adv will revert
back to broadcast flooding automatically.

Long story short, with all these extra measures in place, let's reenable
the batman-adv multicast optimizations to reduce the layer 2 overhead
and in preparation for multicast applications in the future.

The default is enabled for this feature anyway, so removing the
"batctl multicast_mode 0" overwrite is sufficient.
