vendor_available modules were available to product modules.
However, not all vendor_available modules are required to be
available to product modules. Some modules want to be available only
to product modules but not vendor modules.
To cover the requirement, we separate product_available from
vendor_available.
vendor_available will not provide product available module.
Rename libcutils/include_vndk to libcutils/include_outside_system as
it provides the headers to the modules outside the system partition
including /product.

Current per-API level task profiles replace the latest task profiles
rather than overriding the diffs. This poses an issue when a new
feature is added which is applicable to older devices as well we
have to change all per-API level profiles. Change the per-API task
profile support to load the latest task profiles first and then override
with per-API task profiles, similar to how vendor task profiles override
system task profiles. This minimizes the changes we need to do to the
per-API level task profiles going forward and is more consistent with
how vendor task profiles work.

This introduces clusters of CowOperations to the Cow Format, improving
reader performance by allowing many operations to be read at once.
When the header's cluster_ops is a nonzero value, operations will be
clumped into packs of that number, where the last op is a special
CowClusterOp, which points to the start of the next cluster. Each
cluster is immediately followed by it's data, with the footer following
at the end of the file.
cluster_ops must not be 1, as we must include a CowClusterOp in each
group.

libcutils' thread local stuff is almost unused already, so let's try
harder to prevent new users. (In parallel I'll try to actually move the

Enable the uid/pid hierarchy for all groups when using cgroup v2. Mount
the hierarchy under the cgroup v2 root. Make sure that all files under
the hierarchy are accessible by the system user.

the working of the freezer from logs and by checking statuses of
processes.

Current implementation updates the permissions of sysfs
nodes of a device upon the following actions: "add",
"change" and "online".
But certain sysfs nodes (ex: wakeup capabilities under
power management) of devices are not present when the
device is added, but these are generally dependent on
the device driver and are added once the driver is bound.
This is particularly common in USB host stack.
If the bind action events are not parsed the ueventd
will not update the permissions of these nodes.
Hence, add the support for updating permissions on
bind action as well.

Kernel will batch the merge operations only when
block numbers of source and cow device are contiguous.
Daemon will read the COW file and post-process
the operations so that kernel can batch merge the potential
operations.
There are two key changes done in post-processing:
1: COW file contains all the copy operations at the
beginning of the file. We cannot allow batch
merging of COPY operations as a crash in between
the overlapping copies can result in a corrupted state.
Hence, allow copying individual blocks at a time.
2: Replace and Zero operations can be batch merged.
However, reading our existing COW format as-is
will not allow kernel to batch merge. Hence,
process the operations in such a way that kernel can batch
merge them.
Furthermore, it is observed that sync() after every
merge is a overhead. Hence, we will only sync()
for copy operations only. For replace and zero
operations, we will not explicitly sync. This is ok as
crash in between replace/zero merge operations can
redo those operations. However for copy, we have
to make sure that sync is completed before next copy
operation is initiated.
Merge time of a full OTA on bramble is around ~60
seconds as compared to ~10+ minutes prior to this
optimization.
Note that we still have copy operations which are not
batch merged. Hence, OTA with significant number of
copy operations can still have overhead on merge timings.

Refact cow_snapuserd unit test. This will
test code changes in daemon in isolation. Currently it tests
1: Reading snapshot device and validate data
2: Merge and validate data.
More tests related to merge will be added later; but this
should provide a baseline unit test for daemon.
