Moving the scripts to a common directory not only vastly simplifies the
zzz-gluon-upgrade script, but also allows to define an ordering of such
scripts across packages.

This also fixes a long-broken legacy upgrade script which would leave the
sysconfig variable lan_ifname unset and the LAN ports unusable.

add section "system" to gluon-node-info with new option "role" and luci package to change role via config mode

gluon-setup-mode: allow skipping on first boot

gluon-announce: rename announce.lua to collect.lua

add package gluon-luci-node-role; depends on package "gluon-node-info"; depends on new site.conf section

"gluon-node-info": add section system and option role; add announce script to announce the role as nodeinfo;
add invariant script "001-node-system" to add section "system" if not exist; add invariant script "010-node-role"
to add section "system" if not exist; add invariant script "010-node-role" to set role to default value
(site.roles.default) if not exist; depends on new site.conf section

By setting setup_mode.skip to true in site.conf the device will skip
setup mode on first boot.

When an early reboot is triggered because an upgrade script has disabled the
config mode, we need to explicitly call /etc/init.d/done, otherwise the overlay
will not be finalized after a firstboot and we get an endless reboot loop.

was gluon-announce.devs before

the gluon-announced package installs a hotplug script
that uses announce.lua from the gluon-announce package.

So we need to include gluon-announce as dependency.

This should reduce memory consumption a little.

gluon-ebtables-filter-multicast: allow hop-by-hop options as ICMPv6 is sometimes prefixed by an HBH header

the ports were interchanged, see the following packet flow:

client:546 --> [ff02::1:2]:547
server:547 --> client:546

therefore we need to allow outgoing multicast packets with dst-port 547
and unicast packets from bat0 to clients with dst-port 546 and 547 in the other direction
