This now combines all the "libsparse" libraries into the same soong
target. A minor side-effect of this change is that the libsparse
static library depends on the libz shared library instead of the libz
static library. This minor change has no effect since targets using
the static libsparse library need to explicitly include either the
static libz or the shared one.

This allows a remount to be performed on partitions which have been
verified at boot, without causing the verity service to complain of
"corrupted" blocks that could have been modified as a result of a
remount (while the verity checksum remained unchanged).

Running dm-verity on heavily accessed partitions leads to performance
slowdowns, especially on low-RAM and slow-CPU devices.
This patch introduces a flag to allow an entire verified partition to be
read once at boot, to check for corruptions. If the reads are
successful, we can mount the partition as raw & read-only, and if not,
we can revert to mounting it as a verity partition, just like before.
Usage of this flag will entail a slowdown of time-to-boot, but should
lead to improvements in runtime performance.

- Drop forced (-f) e2fsck check when the product has
enabled new ext4 generation by setting TARGET_USES_MKE2FS.
- The new generation tool is supposed to give better stability,
thus justifying dropping -f.
- This should help reducing boot-up time as full check (-f) can
increase boot-up time significantly depending on amount of data.

Change tzdatacheck to account for bundle format changes:
The update bundle now contains a bundle_version file to enable
us to detect changes to the format of the files in addition to
just checking the IANA rules version. The version will be
incremented as we make incompatible changes to the structure
of the bundle (e.g. the files present or their names), the
file formats or the file contents.
The old assumption was that a system image would typically
contain newer rules than had been pushed via ConfigUpdater
and we'd never get rid of the tzdata file from the bundle
content.
If Android makes rule updates routinely or makes substantial
changes to the timezone data files between major releases
then this assumption becomes (even more) untenable.
The bundle_version file in the bundle is expected to contain
the ASCII bytes for "001". This could be extended
in a future version to include minor versioning information
(e.g. "002.001") and so the code here only reads the first
three bytes. This allows for a future change to add the minor
version suffix and optionally increment the major version if
required.
Some error conditions that were previously treated as fatal
are now handled more elegantly. Generally if things are not
as expected with the installed bundle in /data tzdatacheck
will attempt to delete it. The return code of the binary is
used to distinguish between failure cases, which will be
used in a future automated test.
Some of the ConfigUpdater deletion code has been temporarily
retained (with a TODO) so the v2 of the installer code can be
used with ConfigUpdater/ConfigInstaller and keep something
like the existing process working until we have replaced it
with some thing better.
Using the v2 installer code with ConfigInstaller is one
possible fallback if the new distribution approach is not
completed in time.

Deal with recovering after transitory failures surrounding logd
crash or recovery. Improve the chances that the logging functions
can work in a signal handler, not officially supported, but making
sure logging is not blamed for system lockups when misused.
Reorder gTests so that setuid(AID_SYSTEM) is performed after
liblog.enoent test, and that this occurs after other tests that
like to see buffers with content in them as we stop logd.
