[PATCH v4 2/2] configurenetwork: Rearrangement/redesign of central commands

This patch rearranges the commands in configurenetwork. The main
goal is to avoid code duplications and make reading easier. Some
"bugs" were addressed on the way:
- Previously, ONEPORT devices went through both major blocks,
  resulting e.g. in useless eth0.X interfaces being set up (and
  perhaps lots of other strange things). Now, the routines for
  ONEPORT and normal devices are separated.
- Updating the /etc/sysctl.conf has been combined to a single
  block based on variables set earlier
- WANDEV is reset to WANDEV.2 were applicable to reduce number of
  ifs
- "uci del uci set" has been changed to "uci del"
- Spaces have been changed to Tabs were changes were done
- Arguments have been quoted in various places
- Double brackets have been replaced by single brackets
- ETHMODE if has been changed to use BATMAN as default (elseif
  changed to else)
- Use ETHMESHMAC for ONEPORT, introduce ETHMESHDEV
- Shift bit of ROUTERMAC for ONEPORT's ETHMESHMAC

Tested successfully on WR841N v12 and Unifi AC Mesh

Changes in v2:
- Merged with ETH0MAC replacement patch

Changes in v3:
- Don't write comment to /etc/sysctl.conf

Changes in v4:
- Rebased and used en-/disableAutoConf
