353c3c7d81 magiskboot: add unpack -n to help with repack validity tests
- support unpack without decompression to allow easy testing of magiskboot's header, structure and hashing handling by comparing repack checksum versus origbootimg
- make -n first to match repack

c42a51dcbb Add support to patch DTBH DTBs
Apparently, Qualcomm is not the only on creating weird DTB formats,
Samsung also have their own DTBH format for Exynos platforms.

e0927cd763 Add support to patch QCDT
Old Qualcomn devices have their own special QC table of DTB to
store device trees. Since patching fstab is now mandatory on Android 10,
and for older devices all early mount devices have to be included into
the fstab in DTBs, patching QCDT is crucial for rooting Android 10
on legacy devices.

Close #1876 (Thanks for getting me aware of this issue!)

a48c4f9e05 magiskboot: don't clobber /overlay with cpio restore anymore
- Magisk "dirty" flashes would remove the /overlay directory which might have been put there by a custom kernel or other mod
- this is a leftover from when Magisk itself used /overlay for placing init.magisk.rc, so just remove this file specifically and leave the rest intact

ee407472cf magiskboot: allow forcing no recompression on ramdisk.cpio
- when input image had a compressed ramdisk magiskboot had no way to force the repack with the uncompressed ramdisk.cpio since it does not formally recognize cpio as its own format, so add a switch to support forcing repacking to any possible ramdisk format regardless of input image

f341f3b2dd magiskboot: accept forcing recognized but unsupported format compression
- when input image had a different supported format (e.g. gzip) magiskboot would not accept a manually compressed ramdisk or kernel in an unsupported format (e.g. lzop) despite being able to recognize it, so instead would double compress using whatever the input format was, breaking the image with, in effect, a ramdisk.cpio.lzo.gz

e72c6685ed Support A only System-as-root Devices
Most Chinese devices (and supposedly Galaxy S10) running Android Pie
is using system-as-root without A/B partition.

https://source.android.com/devices/bootloader/system-as-root#about-system-as-root

According to the docs above, these devices will have a ramdisk block
with size 0 in their boot images. Since magiskinit can run independently
on system-as-root devices, we simply just create an empty ramdisk with
magiskinit added as init.

Huge thanks to @vvb2060 for the heads up and original PR.
