- this supports custom kernel users to continue not having to fastboot reflash vbmeta with --disable-verity and --disable-verification, now that Magisk 24303+ no longer patches avb out of the fstab on-the-fly at boot time
- checks for an avb option in the fstab entry for the current partition
- if found, it checks if verity or verification is disabled on the top-level vbmeta, and if so, appends a hashtree and FEC data to the partition and updates the hashtree descriptor in the vbmeta partition referenced in the avb option
- add flash_generic support for flashing to dynamic/logical partitions larger than stock using phhusson's lptools binary
- enable full automated support for flashing custom vendor_dlkm.img (note: must NOT be sparse format; factory images are sparse, but images generated from source are not)

- exclude "zimage" as a compression type since magiskboot unpack, split and repack handle it automatically and there is no fallback
- ensure $comp is a working command for all busybox compression fallbacks
Patching system partition entry won't work if system_ext partition is present. Fix this by adding [[:space:]] to the end of the pattern.
Note that grep -w can't be used in this case because there is still a possibility of erroneous matches from grep using / as a whole word delimiter, e.g., logical vendor partition (that is just "vendor") and "/vendor/dsp".
- some devices fail to boot when magiskboot changes the vbmeta flag is set in the AVBv2 signature from 00 to 03, this allows disabling that behavior
- set keep_vbmeta_flag=1 in anykernel.sh to force it to keep whatever's there, =auto will take it from the existing image if Magisk-patched (Canary 23016 or later), and =0 will allow the default magiskboot behavior
- fix duplicate kernel version (vertmp) entries from some kernels
- don't use head when grep -m1 will suffice
- fix some (bad) OEM prop files including entries twice, use last entry like live system
- Use similar dtbo.img logic
- Support new hdr v4 images without repacking
- Process before boot to safe bail
- No resize available, checks output size and bounces if larger
- Handle block state correctly to fix boot check warning

- boot_img_hdr_v3 now has dtb stored in a new partition called vendor_boot
- allow block=vendor_boot partition detection
- support current practice of Image* and dtb in zip root by automatically creating a multi-partition AK3 zip setup from these files (ramdisk directory is assumed to be for the boot partition)
- fix reset_ak current files cleanup
- unpackbootimg/unpackelf kernel+ramdisk suffixes were corrected to match their corresponding mkbootimg argument in my latest forked tools (AIK-mobile v3.8)
- fix repack from unpackelf to mkbootimg broken base value introduced with AK3 rewrite
- touch up a couple pesky minor things
- add global scope to replace_line and remove_line so they match replace_string, and can now work on all matches found in a file
- fix naming BootSignature_Android.jar -> boot_signer-dexed.jar for my own builds (see https://issuetracker.google.com/issues/143810860)
- correct unpackbootimg/unpackelf suffixes which now correspond to their matching mkbootimg argument
- for A/B OTAs my FlashAfterUpdate addon.d script requires the zip to know about addon.d-v2 and act accordingly
- signify support with #FLASHAFTERUPDATEV2 tag in updater-script to pass whitelist check since the majority of zips will not work correctly
- with do.systemless prop enabled in anykernel.sh, will push the contents of modules/ to create a simple "ak3-helper" Magisk module, where testing on devices thus far shows it loads early enough that even replacement kernel object .ko modules will get loaded
- the ak3-helper module info is populated from the kernel.string and parsed kernel version from the kernel being flashed, and if at boot time a different kernel is detected the module automatically removes itself before being loaded to avoid conflicts
- since logical partitions and ext4-dedup on Android 10 now prevent mounting /system or /vendor rw under any circumstances, this feature gives kernel developers back the freedom they had before all this to improve kernel .ko modules, .conf files, etc. with the added bonus of it cleaning up after itself
- only repatch when there is an Image* (i.e. don't attempt on ramdisk-only mods)
- make sure new ramdisk is already copied before trying to detect Magisk patch state in case it changed
- clean up Magisk patch state and exported variables immediately
- also check patch status as part of repack_ramdisk() to avoid any issues if developer is forcing a compression format change
- get full Magisk patch status value and extract Magisk config to export correct environment variables for dtb patching
- running reset_ak before an unpack would remove any included ramdisk files from zip, so only remove if $split_img is detected suggesting an unpack has already occurred
