The mock RPMB can get out of sync with TD storage blocks in the event of
panic or crash. Making this O_SYNC will prevent this from happening.

There is documentation for how AIDL works with ctl commands or
interface_start commands, however it seems we were missing documentation
on declaration of interfaces.

Use the new "data_libs:" to specify test library dependency. This is
like "data:" and it treats compiled libraries as test data files.
The result is libutils_test_singleton{1,2} is picked up by libutils_test
and installed next to the test binary.
Mark the test libs libutils_test_singleton{1,2} as uninstallable. This
prevents installing libutils_test_singleton{1,2} directly and only
permits installing via "data_libs:".

In testing, I saw that the 'main' and 'events' log buffers were set to
incorrect sizes when they were intended to be >= 4MB. The bug is
tracked down to an invalid line in
__android_logger_valid_buffer_size():
/* maximum memory impact a somewhat arbitrary ~3% */
pages = (pages + 31) / 32;
There are two issues with this line:
1) That is not the right calculation for 3%.
2) `pages` is a static variable, so it repeatedly is decremented until
reaching 1.
The consequence is that this function gives invalid results for the
first few calls, then returns true as long as the input is between
LOG_BUFFER_MIN_SIZE and LOG_BUFFER_MAX_SIZE. That check is enough, so
the rest of this logic is removed.
Test: buffers are set to the right sizes.

This is useful for test code that wants to statically link the IP
checksum code. This is not currently possible because libnetutils
is vendor_available and making it available for static linking is
discouraged.

In rescue mode, if /metadata is mounted but /metadata/ota does
not exist, immeidately unmount /metadata and fallback to the code
path when /metadata is not mounted; that is, old partitions are
overwritten.

Now we have more things e.g. loading kernel modules, initialize
selinux. And before all these, system cannot make further progress. It
should be beneficial to boost this critical peroid in init.
Benchmark on a Pixel device shows this saves 100+ms on early boot

build.prop files under system_ext, product, and odm partitions are moved
to the ./etc subdirectory. This is to be in-line with the established
practice of having all configuration files under ./etc subdir.
build.prop doesn't need to be an exception.
However, system/build.prop and vendor/build.prop were not moved because
there are a lot of apps and tools that depend on the path.

For partial updates, the metadata for untouched dynamic partitions
are just copied over to the target slot. So, verifying the extents
of these partitions in the target metadata should be sufficient for
correctness. And we don't need to read & hash the bytes on these
partitions.

Q liblp only supports 10.0 super partition metadata, so
forcefully downgrade the current metadata version too.
On retrofit Virtual A/B devices, the metadata version is
at most 10.1, because the new VIRTUAL_AB flag is not set
on retrofit devices.
In version 10.1, two per-partition flags: UPDATED and DISABLED
are introduced.
- The updated flag is set when the device undergoes a Virtual A/B
update before. Clear it.
- The disabled flag should only be set on metadata files used by
libfiemap ImageManager. It shouldn't be used on super partition metadata.
Hence, this CL should only clear UPDATED flag.

If a device doesn't support unflattened APEXes, init activates flattened
APEXes instead of apexd.
Because apexd dumps apex-info-list.xml after it activates all APEXes,
init should do the same thing.
