fs/squashfs: Add block size option One advantage of squashfs over similar technologies is the support for bigger block sizes. However the default size is not a lot bigger (typically 128k if no `-b` flag specified). This patch adds the ability to select from common block sizes which for example can aid in improving compression ratio.

fs/squashfs: Add option to compress with extreme options mksquashfs allows to tweak many compressions parameters. Currently they can't be changed from kmenu. Leaving out potential space savings. This adds the option to enable a set of predetermined compression options. This option is enabled by default for lz4 since lz4 currently implicitly added the extreme to it in the makefile. So this aids in keeping backward compatibility.

fs/squashfs: honour the number of parallel jobs By default, mksquashfs uses all the CPUs available, like us with BR2_JLEVEL=0. However, by setting BR21_JLEVEL to non-zero, a user volutarily limits the number of jobbs allowed to run concurrently (for various reasons, like this is not a priority task on the machine; or like the autobuilders, to spread the load accross multiple runs without overloading the machine). So, propagate tthe parallelisn settings down to mksquashfs, to repect the user's will. Signed-off-by: "Yann E.

fs: make it behave a bit more like the package infra Currently, to register a filesystem, one has to call: $(eval $(call ROOTFS_TARGET,blabla)) This is very unlike the package infrastructure, where the name of the package is automatically guessed by the infra.
