fastbootd is a userspace daemon that runs in the recovery
ramdisk. It allows writing single partitions to the super
partition via fastboot CLI. When TWRP sees the fastboot option
in the misc partition during startup, it will start with
the fastbootd page and fastbootd running. Otherwise it will
run recovery normally.

hwservicemanager and servicemanager are needed for decryption
and fastbootd in TWRP. Include these services by default since
they are standard Android services and independent of device
tree or SoC.

This will support updating the ramdisk to a different
compression format and co-exist with magisk.
We are also cleaning up and removing non android-10
api makefile actions.
We are also moving twrp repacking to its own class. We
check the new ramdisk format and if it's different
we have magisk compress using the new ramdisk format.

fscrypt aosp doc: https://source.android.com/security/encryption/file-based
kernel fscrypt doc: https://www.kernel.org/doc/html/v4.18/filesystems/fscrypt.html
This commit implements the ability for TWRP to use fscrypt to decrypt
files on the fscrypt implementation. It has been implemented mostly
in a new successor library to e4crypt called libtwrpfscrypt. Most of the
code was ported from AOSP vold.
Notable updates include:
- updated policy storage by libtar
- lookup of fbe policies by libtwrpfscrypt
- threaded keystore operations
Big thanks to Dees_Troy for the initial trailblazing
of encryption in TWRP.

This function will automatically decrypt .ozip file in a .zip and it will
save the .zip in the same folder of the .ozip and with the same name.
After the decryption, the flash will start.
To enable this function you have to set a Boardconfig flag with the
decryption key like i did here:

(cherry picked from commit 0ff59845f2f8dddedb4cee9a9faf86a6294cce66)
This patch uses the loop device to mount files under
/sbin/ from /system/apex in order for the device to
use libraries or other files store inside these files.
Each apex file is mounted over a loop device into a
directory correpsonding to the apex filename under
/sbin/.
Once apex mounting is completed, TWRP will set a
property twrp.apex.loaded to true so that init
can use them as a LD_LIBARY_PATH source.

We are now requiring fstab v2 for android-10+ trees. You can
specify twrp flags using /etc/twrp.flags to label and
annotate partitions.
This patchset uses fs_mgr to load the super partition and build
device mapper blocks off vendor and system depending on the slot
in use. These are mapped to partitions in TWRP and allowed to
be mounted read-only. The super partition is also mapped into a
TWRP partition in order to backup the entire partition. You cannot
backup individual device mapper blocks due to the device can only
be read-only. Therefore you cannot write back to the device mapper.

This allows flame to boot TWRP. Still will need to work on
super partition for vendor and system access.
The plan will be to cherry-pick any updates to android-9.0
through gerrit.twrp.me to this branch as a WIP.
/sbin must come before any other search path when TWRP is built for a
different version of Android than the one on which it will run.
Otherwise, as soon as any of the other paths becomes available via
direct action (i.e. the user mounts a file-system) or indirect action
(e.g. the user flashes a zip that mounts a file-system), incompatible
libraries will be prioritised and loaded instead of the correct ones
from /sbin in TWRP's ramdisk.
This will cause severe disruption of the TWRP environment. Toybox and
other dynamically linked binaries will immediately cease to work; and
since Toybox provides umount, it typically won't be possible to recover
from this state without a reboot.
For example, the following occurs when a Toybox applet is run on a
Samsung Galaxy S10 running Android 10, but using a version of TWRP built
for Android 9:
android:/ # getprop ro.boot.bootloader
CANNOT LINK EXECUTABLE "getprop": cannot locate symbol "_system_properties_init" referenced by "/system_root/system/lib64/libselinux.so"...

* For EXT2/3:
* Align mke2fs options with Android 9.0 fs_mgr_format.cpp.
* For EXT4:
* Note that make_ext4fs is still in use on Android 8.1 to workaround
a FDE encryption bug even though mke2fs has become the default
choice. The bug is fixed in Android 9.0+.
* For F2FS:
* Drop the broken "-r" option, it's never ported to O, explicitly
pass number of sectors instead.
* Keep all options aligned with Pie fs_mgr.
* Check existence before start wiping, as Wipe_EXT4 does.
* For all:
* Calculate block size at runtime, and reserve the space specified
via negative "length" option from fstab. Note that positive length
will be ignored.
* If the partition has crypto footer, and "length" is not specified
in fstab, automatically reverse CRYPT_FOOTER_OFFSET (16384).
* Remove the default crypto key location: footer, this is a bad
assumption since most partitions don't use encryption! We need to
know the real situation to decide whether to reserve crypto footer
on format.
* If the current action is "wipe" or "change filesystem", wipe crypto
footer or block device after mkfs if the partition is
unencrypted or undecrypted (e.g., wrong password).
* If the current action is "format data", unconditionally wipe crypto
footer or block device.

This update splits old MTP code and new MTP code from Google
into two trees, legacy and ffs. Depending on the SDK level,
the build system will select the correct version. The reason
for separating the versions out are due to older android trees
not supporting the updated MTP code from Google.
Most MTP code is from Google, with additions needed from
implementing the Java functions in C++ for TWRP and FFS.
We assume if you are in android-9.0 or above, your kernel
has support for FFS over MTP. Verify that your init.rc
is mounting the MTP FFS driver to the proper location.

Some devices do not declare BOARD_CACHEIMAGE_PARTITION_SIZE.
This case is detected and required modules are added to LOCAL_REQUIRED_MODULES.
However, := is used instead of += and causes the loss of all previously added modules.
The end result is that twrp is not actually getting built since its module was lost.
Fix that by using += when adding modules required for cache-less devices.

On some devices (e.g. ASUS Zenfone) the serial number of the device
is stored in a file in the /factory partition. Consequently, the only
way to load it is using a user space application during the init
process, and to update the ro.serialno system property.
In most places, TWRP already uses the system property to get the
serial number of the device. However, when generating the device ID
used for the backup folder name it checks the boot command line
directly. On these devices, the serialno is not included on the
command line.
Add a TW_USE_SERIALNO_PROPERTY_FOR_DEVICE_ID option that enables
usage of ro.serialno for generating the device id. It is disabled
by default to avoid changing the device id on existing ports.

The recovery-persist used to look for the related recovery logs in
persist storage, and copy them under /data/misc/recovery during the
normal boot process.
As we also want to find out the sideload information from last_install,
it makes more sense to move the parse & report of non-a/b metrics to
recovery-persist. Thus we can avoid the race condition of the file
system between the native code and RecoverySystem.
