- introduce reset_ak function to reset the /tmp/anykernel directory to allow for multi-partition mods; use after changing the AK2 shell (block, etc.) variables again
- make patch_cmdline more intuitive; match the string, and if it doesn't exist add the replacement string, and if so replace with it
- allow AVBv1 signing of recovery by adding simple partition type detection based on name
- restore LD_LIBRARY_PATH after AVBv1 signing to be friendly to recovery when flashed in between other zips
- split dump_boot into split_boot + unpack_ramdisk and write_boot into repack_ramdisk + flash_boot
- fully backwards compatible as dump_boot and write_boot still exist and call these new functions (i.e. no changes needed to anykernel.sh)
- those that wish to do zImage-only AK2 packages can now use split_boot intead of dump_boot and and flash_boot instead of repack_ramdisk in their anykernel.sh
- add failsafe check for failed boot-new.img creation to ensure abort before wiping target partition in edge cases
- hide some expected stderr for AK2 mods with no additional ramdisk files
- fix U-Boot support by passing correct repacked ramdisk filename
- fix multi-compression support during repack derp
- fix cleanup on successful flash not working due to double match from cleanuponabort
- dtbo may be added as dtbo or dtbo.img to the base of the zip
- new Pixel 2 ro.boot.slot doesn't contain _ like Pixel ro.boot.slot_suffix does
Thanks @nathanchance for the majority of the work and research on this one, via #12
- ramdisk_compression=auto; (or undefined) in anykernel.sh is the default, automatically repacking with the detected unpack format
- changing auto to gz lzo lzma xz bz2 lz4-l (for lz4 legacy) or lz4 force the repack as that format
- to this point only gzip was supported, so add support for bzip2, lzop, lzma, xz and lz4 by detecting file magic via plaintext od dump comparison
- busybox contains all necessary formats except for lzma/xz compression (has decompression), and lz4 so add both of these binaries to the minimal default setup

Users may forget to place the commas for removal or they may want to
remove something in the middle. This will remove all commas at the
beginning and end and will make sure there are only single commas
between entries.
Examples:
Options: ro,barrier=1,discard,errors=panic
patch_fstab fstab.qcom /system ext4 options "discard,errors=panic" ""
patch_fstab fstab.qcom /system ext4 options ",errors=panic" ""
patch_fstab fstab.qcom /system ext4 options "errors=panic" ""
patch_fstab fstab.qcom /system ext4 options "discard" ""

After aa1377c, trying to remove part of the original string was not
possible.
Example:
patch_fstab fstab.qcom /system ext4 flags “wait,verify” “wait”
Because "wait" is within "wait,verify", the entire if block will miss
since grep will succeed in finding it. To work around this, we'll
allow users to leave the last part blank and put in the part they
want to remove as the fifth parameter.
Example:
patch_fstab fstab.qcom /system ext4 flags “,verify” “”

- add workaround for malformed ramdisks without leading directory cpio entries
- explicitly set ramdisk root directory to 755 (AOSP default) to avoid issues in some environments
- the 'original string' ($5) was not being used, instead the entire part was always being replaced with the 'replacement string' ($6)
- replace the target 'original string' of the entry part with 'replacement string' as expected/intended
NOTE: any properly written patch_fstab commands with original string as the complete original part WILL remain working as this is a backwards compatible change
- add built-in support for rkcrc for Rockchip board devices signed ramdisk image (see: https://github.com/rockchip-linux/rkflashtool)
- add built-in detection and support for Barnes & Noble Nook 'Green Loader/Green Recovery' signature
- sometimes it's difficult to anchor to specific end lines due to variations across ROMs, so allow the end line to be blank " "
- note this will also remove the trailing blank line so for replacements a trailing \n should be added to maintain spacing; this should be pretty intuitive since you are including the blank line as the end line search
- some Samsung device images can be unpacked and repacked with the standard tools but the id sha1 is offset differently than in the standard header resulting in broken hash type detection
- add built-in support for dumpimage/mkimage for DENX U-Boot uImage devices (see: http://git.denx.de/u-boot.git)
- add built-in support for pxa1088-unpackbootimg/pxa1088-mkbootimg for Marvell PXA1088 board devices' deviation from the AOSP standard (see: https://github.com/osm0sis/pxa1088-mkbootimg)
patch_prop:
- if matched name is not present, appends new prop entry to the end of the file
- if matched name is present, replaces the entry with the new value
- use proper variable for ramdisk in mkbootfs support
patch_cmdline:
- if match not present, appends to the end of the current commandline
- if match is present, expands to full string (to allow for item=value entries), and optionally replaces with a second string, or just removes the entry, then cleans up doublespaces and trailing whitespace
- Chainfire inlines support for this into SuperSU (unlike the similar LG Bump support which must be added via /data/custom_boot_image_patch.sh), so we must also.
- on Sony devices supporting standard boot.img on unloacked bootloaders first AK2 flash would convert from ELF to boot.img, but second flash would attempt to use unpackelf again and fail, so fallback to unpackbootimg
- requires updated unpackelf binary for Sony ELF devices (see: https://github.com/osm0sis/unpackelf)
- add built-in support for futility for ChromeOS devices (see https://github.com/osm0sis/futility)
- small path cleanup since we generally need to be in /tmp/anykernel for post-repack anyway
- add built-in support for mtd-utils (nanddump, flash_erase, nandwrite) for MTD-based Android devices that do not work with dd
- wipe boot block with dd before write to be clean/safe (SuperSU zip also does this)
Known working mtd-utils ARM binaries can be found in my FlashIt v2.5 package:
https://forum.xda-developers.com/showthread.php?t=2239421
- add built-in support for unpackelf for Sony ELF devices (see: https://github.com/osm0sis/unpackelf)
- kernel section is not gzipped on ELF devices with non-QCDT/non-ELF dtb, which needs compression and the dtb appended before it can be repacked (thanks @tobiaswaldvogel)
