This change does the following:
- Create /second_stage_resources empty dir at root.
- At runtime:
- At first stage init:
- mount tmpfs to /second_stage_resources.
- Copy /system/etc/ramdisk/build.prop to
/second_stage_resources/system/etc/ramdisk/build.prop
- At second stage init:
- Load prop from the above path
- umount /second_stage_resources

Reading from the base device is incorrect, because if the partition
shrinks, we may still have copy operations from the removed area in the
original partition. Ask the caller to explicitly name the source device
for AddCopy() operations.

This does not implement OpenReader() yet, however, it implements enough
for some vts_libsnapshot_tests to start passing with Virtual A/B
Compression enabled.
Note that OpenSnapshotWriter() has been disabled when linking with init
or recovery. This is to avoid pulling in all the compression libraries
in those places. OpenSnapshotWriter is only designed to be called by
update_engine and will not work outside of normal operation.

This is a re-landing of the original CL, with a few changes:
- The correct device is now returned in MapUpdateSnapshot.
- The old API is used for tests, and the new API is only tested when
used on a VABC device.
- A sync() call has been added to ensure that writes to the base and
target snapshot devices have been fully flushed. This makes
IsPartitionUnchanged detect the MapUpdateSnapshot bug.
Implement OpenSnapshotWriter for non-compressed Virtual A/B. This is
done by adding an OnlineKernelSnapshotWriter class, which forwards all
writes to a dm-snapshot block device.
This also introduces a new ISnapshotWriter class which extends
ICowWriter, and adds features specific to libsnapshot (versus ICowWriter
which is intended only for the new COW format). The OpenSnapshotReader
call has been moved here since the writer retains all the information
needed to create the reader.
To test the new call, vts_libsnapshot_test has been modified to use
OpenSnapshotWriter.
As part of this change, all consumers of libsnapshot must now link to
libsnapshot_cow.

Add CAP_BLOCK_SUSPEND to android.hardware.health@2.0 service so
that when epoll_wait() is waiting on uevents and timer_fd events
it can block suspend to take the necessary action. Without this
permission, eventpoll is going to ignore the flags EPOLLWAKEUP
used in health HAL or healthloop.

The ro.build.version.release property was changed from being the
codename or final name of the current release to be the final name
of the most recent release. Use ro.build.version.release_or_codename
to reconstruct the fingerprint to match what the build system does.
