TP-Link has introduced a compatibility level to prevent certain
downgrades. This information is stored in the soft-version partition,
changing the data length from 0xc to 0x10.
To remain compatible with existing devices and not produce different
images, the image builder doesn't store a compatibility level if it is
zero.

The soft-version partition actually contains a header and trailing data:
* header: {data length, [zero]}
* data: {version, bcd encoded date, revision}
The data length is currently treated as a magic number, but should
contain the length of the partition data.
This header is also present the following partitions (non-exhaustive):
* string-based soft-version
* support-list

The kernel has become too big again for the ar9344-based TP-Link
CPE/WBS devices which still have no firmware-partition splitter.
Current buildbots produce a kernel size of about 2469 kiB, while
the partition is only 2048 kiB (0x200000). Therefore, increase it
to 0x300000 to provide enough room for this and, hopefully, the
next kernel.

TP-LINK published a firmware update for the archer c6 v2.
This updates also reached the factory devices. Newer software version
rejects downgrading to 1.2.x. Use 1.9.x to allow installing the factory images
and have a little bit time to change it again.
Tested on archer c6 v2 with firmware 1.3.1

By using localtime() to determine the timestamp that goes into factory
images, the resulting image depends on the timezone of the build system.
Use gmtime() instead, which results in more reproducible images.

For the TP-Link 4M devices with tplink-v2-image recipe
(mktplinkfw2.c), there are two different flash layouts based
on the size of the (u)boot partition:
device uboot OEM firmware OpenWrt (incl. config)
tl-wr840n-v5 0x20000 0x3c0000 0x3d0000
tl-wr841n-v14 0x10000 0x3d0000 0x3e0000
In both cases, the 0x10000 config partition is used for the firmware
partition as well due to the limited space available and since it's
recreated by the OEM firmware anyway.
However, the TFTP flashing process will only copy data up to the
size of the initial (OEM) firmware size. Therefore, while we can
use the bigger partition to have additional erase blocks on the
device, we have to limit the image sizes to the TFTP limits.
So far, only one layout definition has been set up in mktplinkfw2.c
for 4M mediatek devices. This adds a second one and assigns them
to the devices so the image sizes are correctly restrained.

There is no versioning information in the firmware-utils code nor the
Makefile. Consider it as first release by adding PKG_RELEASE.
Motivation is the tracking of changes in the buildsystem, which requires
versioning of packages.
Also update copyright.

Firmware is binary blob, so there are barely any NULL terminated strings
expected, so we should probably convert all chars into u8 types, and
after that it's clear, that using strcpy doesn't make sense anymore.
This is rather theoretical stuff, but `uint8_t name[PART_NAME_LENGTH]`
means, that you can supply PART_NAME_LENGTH sized name, not
PART_NAME_LENGTH-1 name when NULL terminated.

This patch changes the version code of the image header
from `1.1.99_0.0.0.0` to `99.99.99_99.99.99.99`. This
is neccessary on some devices where the stock firmware
checks the version field, possibly preventing third-party
firmware from being installed.
