Adds support for Alfa AP121F USB powered travel router (looks like an USB ethernet adapter).
There is no factory image, but only a sysupgrade file for this router which can be installed using the inbuilt UBoot web interface.
Configure your PC with IP address 192.168.1.2 and connect the router using its RJ45 port. Hold the reset button while powering the device until all LEDs have flashed 3 times simultaneously. You can now access the fallback web interface using a web browser at http://192.168.1.1 and flash the sysupgrade file.

The field was accidentally removed during the status-page rewrite.

Fixes #1401

gluon-config-mode-contact-info: provide enhancements for german, english and french translation to comply with DSGVO (#1394)

* do not allow to obligatorily require contact information
* add remark that the data is provided voluntarily
* mention how to delete the data
* be very clear about the fact that the data being entered is public and
  can be downloaded and processed by anyone.

This commit adds the ability to show information about the platform on
config-mode reboot.

fixes #1383

Make ubiquiti-rocket-m a separate device rather than a bullet-m alias to
enable USB support and allow adding devive-specific packages.

This commit adds support for the AVM Fritz!Box 4020 WiFi-router.

SoC:   Qualcomm Atheros QCA9561 (Dragonfly) 750MHz
RAM:   Winbond W971GG6KB-25
FLASH: Macronix MX25L12835F
WiFi:  QCA9561 b/g/n 3x3 450Mbit/s
USB:   1x USB 2.0
IN:    WPS button, WiFi button
OUT:   Power LED green, Internet LED green, WLAN LED green,
       LAN LED green, INFO LED green, INFO LED red
UART:  Header Next to Black metal shield
       Pinout is 3.3V - RX - TX - GND (Square Pad is 3.3V)
       The Serial setting is 115200-8-N-1.

Tested and working:
 - Ethernet (LAN + WAN)
 - WiFi (correct MAC)
 - Installation via EVA bootloader
 - OpenWRT sysupgrade
 - Buttons
 - LEDs

Not working:
 - USB port

Installation via EVA:
In the first seconds after Power is connected, the bootloader will
listen for FTP connections on 169.254.157.1 (Might also be 192.168.178.1). Firmware can be uploaded
like following:

  ftp> quote USER adam2
  ftp> quote PASS adam2
  ftp> binary
  ftp> debug
  ftp> passive
  ftp> quote MEDIA FLSH
  ftp> put openwrt-sysupgrade.bin mtd1

Note that this procedure might take up to two minutes. After transfer is
complete you need to powercycle the device to boot OpenWRT.

This commit adds information about:
- how cpu time is spent since boot in jiffies (1/100*sek) (cpu)
    - the value is summed for all cores, so in 10 seconds the
      summed values will increase by 4000, if the cpu has
      4 cores
- context switches since boot (ctxt)
- interrupt counters since boot (intr, softirq)
- forks since boot (processes)

In multidomain setups, VXLAN is enabled by default, but can be disabled in
domain configs using the mesh/vxlan option. In single domain setups, the
mesh/vxlan option is mandatory.

The UCI option for legacy mode is removed.
