Historically it's possible to leave the `SUBTARGETS` undefined and
automatically fallback to a "generic" subtarget. This however breaks
various downstream scripts which may have expectations around filenames:
While some targets with an explicit generic subtarget contain `generic`
in the filenames of artifacts, implicit "subtargets" don't.
Right now this breaks the CI[1], possibly also scripts using the ImageBuilders.
This commit removes all code that support implicit handling of
subtargets and instead requires every target to define "SUBTARGETS".

Many NAND devices use a build recipe with "append-ubi | check-size" to
ensure factory images don't exceed the target flash partition size.
However, UBI reserves space for bad block handling and other operational
overhead, and thus 'check-size' can overestimate the space available by
several MB. In practice, this means a failed check is definitely a failure,
while a passing check is only probably a pass.
Improve the situation by teaching 'Build/append-ubi' to check image sizes
while accounting for UBI reserved blocks. Add new device variable NAND_SIZE
and use with existing IMAGE_SIZE to derate the available space. Each UBI
device reserves 20 PEBs per 1024 PEBs of the entire NAND device for bad
blocks, plus an additional 4 PEBs overhead.
Many devices can transparently enable this check by setting NAND_SIZE based
on their flash storage, and may then remove any unneeded 'check-size'.

FACTORY_SIZE is used as a device recipe variable on both the D-Link

Kernel loaders like the lzma-loader currently don't track changes to

As the loaders are tiny and the build times are insignificant, simply
force rebuilding them on every build to avoid this problem.

Building images usally stores them in KDIR_TMP and then copies them over
to BIN_DIR. This is fine as rebuilding of images overwrites existing
images. When using the EXTRA_IMAGE_NAME variable frequently this fills
up the ImageBuilder KDIR_TMP folder since every built image is stored
forever.
This commit clears the KDIR_TMP folder before building a new image.
Below an example how sysupgrade.openwrt.org filled up after the release
of 22.03.0 where every created image contains a hash of the package

Since the `.sha256sum` file is located in the $(KDIR) folder, switch

With this commit `mksquashfs` may use more cores than defined via `-j`.
This is the same behaviour as for archive creation of ImageBuilder, SDK

The majority of our targets provide a default value for the variable
SUPPORTED_DEVICES, which is used in images to check against the
compatible on a running device:
SUPPORTED_DEVICES := $(subst _,$(comma),$(1))
At the moment, this is implemented in the Device/Default block of
the individual targets or even subtargets. However, since we
standardized device names and compatible in the recent past, almost
all targets are following the same scheme now:
device/image name: vendor_model
compatible: vendor,model
The equal redundant definitions are a symptom of this process.
Consequently, this patch moves the definition to image.mk making it
a global default. For the few targets not using the scheme above,
SUPPORTED_DEVICES will be defined to a different value in
Device/Default anyway, overwriting the default. In other words:
This change is supposed to be cosmetic.
This can be used as a global measure to get the current compatible
with: $(firstword $(SUPPORTED_DEVICES))

Allow a device recipe to specify a custom UIMAGE_MAGIC value, as used by
