FDE is no longer supported, so there's no longer any need to ever
reserve a crypto footer.

Since Android 10, new devices have been required to use FBE instead of
FDE. Therefore, the FDE code is no longer needed.

Since Android 10, new devices have been required to use FBE instead of
FDE. Therefore, the FDE code is no longer needed.
Make fs_mgr reject fstabs where FDE is enabled.
Unfortunately, there is a quirk where the "encryptable" flag (which was
originally meant just for FDE) was overloaded to identify adoptable
storage volumes. It appears that we have to keep supporting this use
case. Therefore, don't reject the "encryptable" flag completely.
Instead, just reject "encryptable" when it appears without
"voldmanaged", or without "userdata" as its argument.
Here are some references for how "encryptable=userdata" is being used to
identify adoptable storage volumes:

Add new CgroupGetControllerFromPath function to retrieve the name of the
cgroup using a file path. If the file does not belong to any cgroup, the
function returns false.

"nonplat" was renamed to "vendor" in Android Pie, but was retained
here for Treble compatibility.
We're now outside of the compatbility window for these devices so
it can safely be removed.
While I'm here, improve accuracy of some comments and
in-code-documentation.
Test: build boot cuttlefish device. adb remount, modify
/system/etc/selinux/plat_sepolicy_and_mapping.sha256 to force
on-device policy compilation. reboot. Verify that device boots
without new selinux denials.

While llkd helps in discovering issues in apps which leave zombies, it
creates issues for dogfooders when apps are killed. Disable it by
default.

Test: boot and check llkd not running

Direct writes for partition flashing significantly increase performance.
Use O_DIRECT flag when opening partition for flashing. Additionally use
a 4096b aligned buffer which is required for O_DIRECT.
Switch from using 8MB write buffer to 1MB write buffer, as the extra
allocation has no performance impact.

Allow caller to pass additional flags when opening a partition. Obsolete
usage of boolean read, and make previous callers use O_RDONLY instead.
Explicitly OR (O_EXCL | O_CLOEXEC | O_BINARY) to keep existing design
working as is.

Most of the test cases are similar to dm-snapshot-merge.
Additional test cases have been added primarily to test
I/O's in parallel with merge.

For the vendor variant of libhealthd_mode_charger, read resources
from /vendor. The core variant continues to read resources from
/product, /system, and /res.

This is a prerequisite to move charger to vendor partition.
Because vendor domains can't read ro.charger.*, they are all assumed
to be the default value. They aren't set in the ecosystem anyway,
so it is time to deprecate them.
