Follow the typical device tree guidelines that a node is only enabled
if it does not have a 'status' property or if it does have a 'status'
property with a value of 'ok' or 'okay'.

This patch adds another uevent-regeneration pass to the first stage
mount. When the super partition spans multiple block devices, we need
/dev/block/by-name symlinks to have been created before we begin mapping
dynamic partitions.

Although metadata is only stored on the first block device, we ideally
want to validate all the block devices before flashing. This patch does
that and in the process converts ValidateAndSerializeMetadata to use
IPartitionOpener.

The library is expected to be a unified place for all components to read
both global and per-process memory accounting form kernel including
getting the working set. This change adds the PageInfo, MemInfo and
ProcMemInfo classes and verifies the implementation against libpagemap
for correctness.
Adds a procmem2 tool show the usage.

The vendor overlay source directory must have the same sepolicy
context with the target vendor directory.
Otherwise, the vendor overlay will fail to mount.
Bug: 112955896
Test: Check if a source directory that has a differnt context fails
to mount on vendor directory.

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
created sysfs nodes won't be labelled.

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.
