Document the behavior of the Outdoor mode when preserve_channels is
enabled.

This change stores a Kernel with Debug-Symbols for the current
architecture in a new output directory '<outputdir>/debug'.
This allows a developer or operator of a network to store the kernel
along with the actual images. In case of a kernel oops the debug
information can be used with the script
'scripts/decode_stacktrace.sh' in the kernel source tree to get the
names to the symbols of the stack trace.

OpenWRT already provides the CONFIG_COLLECT_KERNEL_DEBUG -option that
creates a kernel with debug-symbols in the OpenWRT output directory.
This change enables this option and copies the generated kernel to the
gluon output directory.

(cherry picked from commit 5a7ac058)

This summaries giving an overview of a scripts function and a short summary
how it's doing this. Only the scripts are covered, that are used by the
Freifunk-Berlin firmwarebuiler too.

[Matthias Schiffer: slightly reworded some descriptions]

A microsecond is commonly abbreviated as µs. This prevents confusions
between micro- (µs) and milliseconds (ms).

This adds support for the beacon interval to be set on a per-band base.
This has the potential to reduce the amount of airtime used up for
sending beacon frames.

The 'preserve' flag can be used to mark a peer so it is not removed or
modified on upgrades. In addition, groups containing preserved peers are
not removed.

(cherry picked from commit 4bfcd6ae)

Allows reconfigurtion of remote syslog from within site.conf.

Conflicts with the gluon-web-logging package as user made changes
will be overwritten, because this package will reconfigure the syslog
destination on every upgrade.

Resolves #1845

OpenWRT 19.07 enables urngd by default, so haveged is redundant.

This device has broken Ethernet on both ports.

Remove support for those devices. for now, as there was no feedback from
the original author.
