base-files: add mtd_get_mac_encrypted_arcadyan function
Some Arcadyan devices (e.g. MTS WG430223) keep their config in encrypted
mtd. This adds mtd_get_mac_encrypted_arcadyan() function to get the MAC
address from the encrypted partition. Function uses uencrypt utility for
decryption (and openssl if the uencrypt wasn't found).

6e13794344 base-files: add minimal mmc support
Added minimal mmc support for helper functions:

 - find_mmc_part: Look for a given partition name. Returns the
	coresponding partition path
 - caldata_extract_mmc: Look for a given partition name and then
	extracts the calibration data
 - mmc_get_mac_binary: Returns the mac address from a given partition
	name and offset

c3e252d080 base-files: add function for generating random MAC
This adds a function for generating a valid random MAC address (unset MC
bit / set locally administered bit).

It is necessary for devices which do not have a MAC address programmed
by the manufacturer.

dc61e3b7ff base-files: add functions to set or clear bit in MAC address
Some devices (e.g. Arduino Yun) need bitwise operations during MAC address
setup. This commit adds generalized versions of macaddr_setbit_la(), which
are helpful when manipulating a single bit in a MAC address.

6170c46b47 base-files: rename hostname with EUI of mac address
If a label MAC address is provided for device, system
will rename the hostname with OpenWrt_{eui mac address}.
This helps to distinguish between different devices.

Since it's no good idea to nest json_* functions, this code does
not use get_mac_label directly, but only get_mac_label_dt as
external resource.

a6fbdd3a78 base-files: don't store label MAC address in uci system config
If set, label MAC address is available from one of two sources,
device tree or board.json. So far, the function get_mac_label
was meant for retrieving the address, while an option in uci
system config was specified only for case 2 (board.json).

The uci config option has several drawbacks:
- it is only used for a fraction of devices (those not in DT)
- label MAC address is a device property, while config implies
  user interaction
- label_macaddr option will only be set if /etc/config/system
  does not exist (i.e. only for new installations)

Thus, this patch changes the behavior of get_mac_label:
Instead of writing the value in board.json to uci system config
and reading from this location afterwards, get_mac_label now
extracts data from board.json directly. The uci config option
won't be used anymore.
In addition, two utility functions for extraction only from DT
or from board.json are introduced.

Since this is only changing the access to the label MAC address, it
won't interfere with the addresses stored in the code base so far.

469e347f19 base-files: provide option to specify label MAC address in board.d
For many devices, MAC addresses cannot be retrieved via the
device tree alias.

To still provide the label MAC address for those, this implements
a second mechanism that will put the address into uci config.
Note that this stores the actual MAC address, whereas in DTS
we reference the bearing device.

This is based on the work of Rosy Song <rosysong@rosinson.com>

0340718863 base-files: add function to retrieve label MAC address
To refer to the MAC address on a device's label, one can
specify the alias label-mac-device in the DTS which should
point to the bearer of the corresponding MAC address.

With the function get_mac_label, the user can retrieve then
retrieve this address and use it as a value that uniquely
identifies his device.

This is severely helpful for several downstream functionalities,
e.g. define MAC addresses of custom netifs or change the SSID to
be easily recognizable.

45600124fc base-files: use get_mac_binary() in mtd_get_mac_binary_ubi()
The actual retrieval of the MAC address in mtd_get_mac_binary_ubi()
is the same as in get_mac_binary(). Thus, use the latter function
in the former to reduce duplicate code.

This will also allow to benefit from the enhanced path check there
and bring mtd_get_mac_binary_ubi() more in line with the similar
mtd_get_mac_binary().

4c060228cb base-files: fix mtd_get_mac_text not accepting hex offsets
The mtd_get_mac_text helper method did not support hexadecimal offset
values, resulting them to break after 75bfc393ba ("treewide:
convert MAC address location offsets to hexadecimal")

This commit fixes this by evaluating the hexadecimal input,
converting them to decimal.
