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.

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.

Since we will be iterating forward for user-space
merge, we need to sort the blocks in increasing order
so that blocks can be batch merged if contiguous.
For dm-snapshot merging, we will continue to sort
in decreasing order.

Add new client API's for initiating and tracking merge.
These API's will be used by libsnapshot.
Track the merge completion in the server by walking through
all the partitions. Each worker thread will update the
merge completion as and when number of COW operations
are completed. Server will gather all the completions
of each partition and average it out. This is in sync
with the current merge completion tracking for dm-snapshot.
As a side effect, move the snapuserd_server.h/cpp files to
dm-snapshot-merge directory as it will only be a maintaining
code.

If the I/O request is for a sector which is not block
aligned, then we will not find the mapping directly
to a COW op as each op is block aligned. Thus, we
handle them by chopping the I/O request and processing
the unaligned data. Furthermore, if the request
doesn't map to any of the COW ops, then route the
I/O to the base device.

Now that merging is done in user-space and
partitions are mounted off dm-user directly,
daemon will have to serve every I/O request.
Daemon has to handle this wherein we need to
check if the given I/O request block has been
modified in the OTA. Furthermore, if merge is
in-progress, we will have to synchronize with
the merge thread before servicing the I/O.
If the I/O request maps to a REPLACE or ZERO op,
we will just read the data from COW device.
If the I/O request maps to a COPY or XOR op,
the worker thread will have to synchronize
with the merge thread and if the merge is
in progress, fetch the data directly from RA buffer.
This patch handles I/O requests only if the
sectors are 4k aligned.

The kernel can return different compatible ranges on each call, depending on
how it decides to merge contiguous extents in the results. To avoid the
complexity of requerying the ioctl, just do one query up to the maximum

The system property is set by vendor partition but owned by platform,
hence vendor domains can't read this value. Add an API in
ChargerConfigurationInterface so that HAL implementations can override
its value.
Other ro.charger.* sysprops are unused, hence no APIs are created for
them.

UserLifecycleTests test disables all Little cores in the course of the
test, which causes attempts to add a process into /dev/cpuset/restricted
cpuset cgroup to fail with ENOSPC error code, indicating that a process
is joining a cpuset cgroup with no online cpus. Current libprocessgroup
implementation will log an error on each such occurrence, which spams
the logs and makes it hard to analyze test results. Because this
situation does not happen in production environment (we do not offline
cpus), we can prevent flooding the logs by identifying this case,
logging an appropriate error one time and ignore all later similar errors.
