$snapshotctl apply-update <directory containing snapshot patches>
This command is equivalent to applying incremental-ota but
bypasses all of the update-engine subsystem. Snapshot-patches
which are created on the host will be used directly and
will be written to the COW block devices.
No change to any of the libsnapshot or the I/O path logic.
Once the snapshot patches are applied, device is ready
to reboot as if an OTA update is applied.
Once the device reboots, snapshot merge will be initiated
as usual.
This will help test the changes to libsnapshot + init + snapuserd
extremely quick.
Incremental flashing becomes quite simple in the CI workflow.
Here are numbers tested on live builds where the actual builds/testing
is done on CI.

builds and apply them to the device

Symbols with __INTRODUCED_IN_LLNDK are available for LLNDK only if
the vendor api level set by the RELEASE_BOARD_API_LEVEL is equal to
or newer than the target vendor api level in __INTRODUCED_IN_LLNDK.
This works only for the vendor variants at the same time ignoring
__INTRODUCED_IN annotation for the vendor variants. On the other
hand, __INTRODUCED_IN_LLNDK will be ignored from non-vendor variants.

Alternate dispatching blocks between threads rather than splitting the
data beforehand and then sending to threads in order to ensure that
single threading + multithreading chunks data at the same locations.
Without this change, the resulting op count + data section of the cow
will differ between --enable-threading && --disable-threading at
runtime, which is a result we don't want

It cannot be assumed that file mappings in /proc/<pid>/maps will be
completely backed by the underlying file. [1]
Use MappedFileSize() to deduce the correct ranges for the mlock()
calls when locking system pages in the OTA path.
While at it also clean up the some unreachable code (mlockall()),
and improve error logging.

The test is not eligible for CTS. Reasons:
1. The init behavior does not directly affect app compat. App interact
with init only for the property service and that part is covered by
the Bionic test already.
2. This test doesn't run against the init binary installed on the
device. libinit where most of the init functionalities are
implemented is statically linked to this test binary. In other words,
this test is closer to a unit test for init.
3. This test is not compatible with Trunk stable where test and DUT are
built in different branches. The test depends on several (private)
libraries like libbase and libutils. Since the interfaces of the
libraries may have changed in the main branch, the test binary built
from the old test-dev branch may break.
This change does not remove the test. The test will still run as a unit
test during pre/post submit.
I didn't drop the `Cts` prefix from the name, because that requires
broader changes.

Since variable block compresses blocks and there is no longer a 1:1
mapping between ops to blocks, we need to update this check in
EmitBlocks to the actual number of compressed blocks written.
Since single threaded + multi threaded + no compression invoke different
code paths. Ensure that that blocks written are still equivalent to
blocks.size(). Adding two test cases to cover these situations.
