For retrofit devices where the super partition is not called "super",
this allows the correct partition to be passed via the kernel
command-line, i.e.:
androidboot.super_partition=system
Since retrofitting is only supported for A/B devices, we assume that
a partition named this way must be slot-suffixed.

Under the condition of an existing, but broken, filesystem on the
scratch device, force recreation. Add the -f flag for f2fs,
already present for ext4.
Test is enhanced. The test needs to check, and if necessary wipe
out any existing overrides and reboot before running the remainder
of test. Report which overrides are being used, and how they are
setup. Fail if they are not as expected. Improve efficiency of
checks by reducing the duplication of commands issued to the device.

We need to do restorecon after the cold boot, otherwise the newly

Using fdopendir with unique_fd correctly is more annoying than it
should be, because fdopendir doesn't close the file descriptor
received upon failure.
Add an android::base::Fdopendir that does that handles the failure
case.

Without this, it is much more difficult to ensure that the "a" and "b"
slots are both bootable during development. We already update all
metadata slots for update-super, so we should here as well.

Allow sysrq stack trace dump to be disabled by ro.llk.sysrq_t.
Default is true if not on a limited memory device ro.config.low_ram.

Using overlayfs, the system partition may provide files for older
version of vendor partitions by overlaying on the vendor partition.
Directories in /system/vendor_overlay will be overlaid on the
directories in /vendor to override existing files or provide new
files.
This feature works only if the kernel support overlayfs and has a
patch for override_creds. Otherwise, no-op.
Bug: 114679254
Test: Build and boot: nothing affected without overlayfs, or
vendor file is overrided with overlayfs

The memcg.limit_percent option can be used to limit the cgroup's
max RSS to the given value as a percentage of the device's physical
memory. The memcg.limit_property option specifies the name of a
property that can be used to control the cgroup's max RSS. These
new options correspond to the arguments to the limitProcessMemory
function in frameworks/av/media/libmedia/MediaUtils.cpp; this will
allow us to add these options to the rc files for the programs that
call this function and then remove the callers in a later change.
There is also a change in semantics: the memcg.* options now have
an effect on all devices which support memory cgroups, not just
those with ro.config.low_ram or ro.config.per_app_memcg set to true.
This change also brings the semantics in line with the documentation,
so it looks like the previous semantics were unintentional.
