Add in replace ops to WriterV3 without compression support (will be
added in later). CowReader also has to be changed since we no longer
have a CowFooter (our checks need to be updated correspondingly).
We need next_data_pos_ to be pointed to after the operation buffer. This
section is appended to incrementally as we write replace + xor
operations

Add zero block operation to writer v3. We currently write this operation
to after the scratch space. Once resume point support is added we may
need to change this to write after the resume point. This CL only
supports zero blocks, so writeoperation does not take in data yet.

Add in Parser base class and refactor code to work with it. Base class
will have ops() method which returns a vector of v3 operations.
v2_parser translates it's v2 operations to v3 operations with this
method.

unit tests
1, Previous implementation has the staged prop application done in
property_service, which caused a number of unnecessary changes which
including exposing apis like AddPersistentProperty. In addition, it made
the property_service logic complicated. A better design is to have the
staged value application done while reading the persistent properties
from file. This way, no change to property service. In addition, unit
test is much cleaner and efficient.
2, add a unit test to lock down the behavior. Specifically, it locks down that when a prop is staged, it should be applied the next time when the persistent prop is loaded. In addition, it should lock down that other persistent props are not overwritten.

The max_processes calculation is incorrect for KillProcessGroup because
the set of processes in cgroup.procs can differ between the multiple
reads in the implementation. Luckily the exact value isn't very
important because it's just logged. Remove max_processes from the API
and remove the warning about the new behavior in Android 11.
Note that we still always LOG(INFO) that any cgroup is being killed.

This reverts commit c7a6fe684c.
Repply the blkio controller migration because it was not responsible
for the test failures that led to the revert. See also the following bugs:
* https://b.corp.google.com/issues/260143932
(v2/android-virtual-infra/test_mapping/presubmit-avd test failure)
* https://b.corp.google.com/issues/264620181
(CtsInitTestCases.RebootTest#StopServicesSIGKILL failure)
The only change compared with the previous version is that the io
controller has been declared optional. This is necessary because some
devices have a kernel that does not support the io controller.

If remounting "/system" caused "/" to be set to MS_PRIVATE, restore it
to MS_SHARED after remount.
Bug: 306124139
Test: adb-remount-test
Test: remount /system and verify /proc/self/mountinfo
Change-Id: I12bc2ccdaf7d2b2de330064b61a8533b96defe00
When juggling submounts, the temp dir holding the references to
submounts should be MS_PRIVATE. Otherwise the submount propagation type
would be changed according to section 5d,
https://www.kernel.org/doc/Documentation/filesystems/sharedsubtree.txt
For example, a root mount tree of
<mountpoint> <shared/private>
/dev shared
/product shared
/product/app private
When executing "remount /product", "/product/app" would be moved to a
temp dir under "/dev", which is MS_SHARED. This would also change the
state of the mount to MS_SHARED.
/dev shared
/product shared
/dev/temp shared (moved from /product/app)
Thus after "/product" overlay is mounted, and "/dev/temp" is moved back,
"/product/app" would be unintentionally changed to MS_SHARED.
/dev shared
/product private
/product shared (overlayfs override)
/product/app shared (moved from /dev/temp)
This change fixes this issue by setting up a standalone mount tree under
/dev to hold the temporary moved submounts.
This way we don't need to modify the state of "/dev" whatsoever, and can
guarantee the propagation type of mounts moved in and out of the temp
dir are not changed.

Vendor overlay was introduced to enable system-only update with small
changes on the vendor, but this is no longer required with same reason
of VNDK deprecation - more frequent Vendor update than expected, and
makes system-vendor interface unstable. This change adds more comments
to explain that Vendor overlay will be deprecated along with VNDK, and
skip test if VNDK is deprecated.
