bcm4908img is a tool managing BCM4908 platform images. It's used for
creating them as well as checking, modifying and extracting data from.
It's required by both: host (for building firmware images) and target
(for sysupgrade purposes). Make it a host/target package.

Asus looks for an extra data at the end of BCM4908 image, right before
the BCM4908 tail. It needs to be properly filled to make Asus accept
firmware image.
This tool constructs such a tail, writes it and updates CRC32 in BCM4908
tail accordingly.

Flashing image with BCM4908 CFE bootloader requires specific firmware
format. It needs 20 extra bytes with magic numbers and CRC32 appended.
This tools allows appending such a tail to the specified image and also
verifying CRC32 of existing BCM4908 image.

BCM4908 CFE bootloader requires kernel to be prepended with a custom
header. This simple tool implements support for such headers.

Some Russian d-link routers require that their firmware be signed with a
salted md5 checksum followed by the bytes 0x00 0xc0 0xff 0xee. This tool
signs factory images the OEM's firmware accepts them.

Because some padding values in the TP-Link safeloader image generation
were hardcoded, different values were sometimes used throughout a
factory image. TP-Link's upgrade images use the same value everywhere,
so let's do the same here.
Although a lot of TP-Link's safeloader images have padded partition
payloads, images for the EAP-series of AC devices don't. This padding is
therefore also made optional.
By replacing the type of the padding value byte with a wider datatype,
new values outside of the previously valid range become available. Use
these new values to denote that padding should not be performed.
Because char might be signed, also replace the char literals by a
numeric literal. Otherwise '\xff' might be sign extended to 0xffff.
This results in factory images differing by 1 byte for:
* C2600
* ARCHER-C5-V2
* ARCHERC9
* TLWA850REV2
* TLWA855REV1
* TL-WPA8630P-V2-EU
* TL-WPA8630P-V2-INT
* TL-WPA8630P-V2.1-EU
* TLWR1043NDV4
* TL-WR902AC-V1
* TLWR942NV1
* RE200-V2
* RE200-V3
* RE220-V2
* RE305-V1
* RE350-V1
* RE350K-V1
* RE355
* RE450
* RE450-V2
* RE450-V3
* RE500-V1
* RE650-V1
The following factory images no longer have padding, shrinking the
factory images by a few bytes for:
* EAP225-OUTDOOR-V1
* EAP225-V3
* EAP225-WALL-V2
* EAP245-V1
* EAP245-V3

TP-Link safeloader firmware images contain a number of (small)
partitions with information about the device. These consist of:
* The data length as a 32-bit integer
* A 32-bit zero padding
* The partition data, with its length set in the first field
The OpenWrt factory image partitions that follow this structure are
soft-version, support-list, and extra-para. Refactor the code to put all
common logic into one allocation call, and let the rest of the data be
filled in by the original functions.
Due to the extra-para changes, this patch results in factory images that
change by 2 bytes (not counting the checksum) for three devices:
* ARCHER-A7-V5
* ARCHER-C7-V4
* ARCHER-C7-V5
These were the devices where the extra-para blob didn't match the common
format. The hardcoded data also didn't correspond to TP-Link's (recent)
upgrade images, which actually matches the meta-partition format.
A padding byte is also added to the extra-para partition for EAP245-V3.

this patch fixes/improves follows:
- PATTERN_LEN is defined as a macro but unused
- redundant logic in count-up for "ptn"

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.

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.
