Unlike Markdown, RST uses double backticks for monospace text; single
backticks result in italic text. Use monospace for commands like the
surrounding paragraphs.

Debugging binaries in images that are built with sstrip is extremely
annoying, as not even objdump will work on them.

Switching from sstrip to standard strip increases the ath79 image size
(for some usual Archer C7 v2 configuration I used for testing) by ~70KiB,
or 1.3% of the rootfs size (~1% of the total image size), which is
rarely worth the decreased debuggability.

Extend GLUON_DEBUG to not only distinguish 0 and 1, such that:

- 0 uses sstrip same as before
- 1 switches to regular strip; this is the new default
- 2 includes all debug info, like GLUON_DEBUG=1 did before

The Gluon Tunneldigger protocol handler hasn't received the care and
attention a core package, especially a VPN protocol, should.

Due to the works in #2102 it's no longer required to maintain
VPN handlers in the Gluon Core and they can be instead included via a
package feed.

Users who wish to continue using a supported core Gluon package are
encouraged to take a look at fastd in conjunction with it's null@l2tp method.
It offers roughly the same performance (it's using the same principle
of operation) and supports connections via IPv6 as a bonus.

In general it should be possible to change the VPN used protocol
asynchronously with a normal update.

If Gluon users wish to continue using tunneldigger the recomendation
is to participate in the development of tunneldigger inside our
community-packages.
