e50295d337 magiskboot: add support for lz4 compressed dt (extra)
- legacy devices brought up to Android 10 may now use a compressed dt in a hdr_v0 AOSP dt variant extra section, so detect, decompress and recompress this
- so far these have only been done using lz4 compression (latest format revision magic), e.g. LOS 17.1 victara (Moto X)

02dc1172be Revert DTB patches to in-place binary patches
Since we no longer need to add new properties in the device tree, and
all the patches we do removes strings, we can just directly patch
the flat device tree in-place, ignoring basically all the higher level
DTB structure and format to accomplish 100% compatibility.

5c988510b3 Preserve fdt paddings
Some Motorola devices (Qualcomm kernel with CONFIG_MMI_DEVICE_DTBS
configuration enabled) need 1k of padding to the DTBs to allow for
environment variables to be runtime added by the bootloader.
Those extra paddings will be removed during the process of dtb patch,
devices won’t be able to boot-up and return to fastboot mode immediately
after flashed the flawed boot.img.

7f6a6016d6 magiskboot: add simple workaround for Samsung offset header variant
- some Samsung devices (e.g. Galaxy S5 SMG-900H) use a slightly different AOSP bootimg.h variant with `#define BOOT_NAME_SIZE 20` instead of 16
- since all known examples of these device images do not have anything in the NAME or CMDLINE fields, and the bootloader also accepts standard AOSP images, simply offset the SHA1/SHA256 detection by 4 bytes to avoid false positives from these images, remain an equally effective detection shortcut, and ensure a proper SHA1 checksum on repack

aosp-dtbhdt2-4offhash-seandroid-256sig-samsung_gs5-smg900h-boot.img
UNPACK CHECKSUM [00000000b11580f7d20f70297cdc31e02626def0356c82b90000000000000000]

This patch should result in a `magiskboot unpack -n boot.img; magiskboot repack boot.img` new-boot.img matching the AIK CHECKSUM above.
