This change splits out the selinux initialization and supporting
functionality into selinux.cpp and splits the security related
initialization of the rng, etc to security.cpp. It also provides
additional documentation for SEPolicy loading as this has been
requested by some teams.
It additionally cleans up sehandle and sehandle_prop. The former is
static within selinux.cpp and new wrapper functions are created around
selabel_lookup*() to better serve the users. The latter is moved to
property_service.cpp as it is isolated to that file for its usage.

(cherry picked from commit 9afb86b25d8675927cb37c86119a7ecf19f74819)
In debuggerd, when dumping a tombstone, run the new unwinder and verify
the old and new unwinder are the same. If not, dump enough information
in the tombstones to figure out how to duplicate the failure.

Test: Builds, ran and forced a mismatch and verified output.

Inspired by ag/2659809/, this CL add readahead built-in command in init
to let files be prefetched into pagecache for faster reading.
Readahead happens in background but due to filesystem limitation it
might take small amount of time in it reading the filesystem metadata
needed to locate the requested blocks. So the command is executed in a
forked process to not block init execution.

- The pc read from the eh frame binary table of pc/fde offset is off by 4.
I verified that on arm/arm64/x86/x86_64 the pc in this table matches
the fde pc_start value. I did this by adding an error if this occurred
and ran unwind_info over everything in system/lib, system/lib64, system/bin.
- Fixed unit tests for the above change.
- Fix a small bug in the processing encoded values. The high
bit of the encoding should be masked off, but I wasn't doing that. That
meant during processing of the fde, I was incorrectly returning
an error because the encoded value was unknown.
- Added a new test for this encoding change.

Test: Build and all unit tests pass. Also, see above comments.

AttestKeyResponse may be larger than 4K (always less than 8K) when
attesting an RSA key. This change allows the non-secure side to read a
response that may be larger than 4K by adding an additional bit
indicating the end of a response. If a message command has the
KEYMASTER_STOP_BIT set, then the non-secure side knows that the response
has been fully read.
Test: android.keystore.cts.KeyAttestationTest#testRsaAttestation passes
with production attestation key and chain, when AttestKeyResponse is
larger than 4K.
Tested with other CTS tests when keymaster messages are smaller
than 4K, still passes.
Manual test to verify that a tipc error due to large message size is
handled correctly.

service.cpp, which is part of libinit, references symbols in
property_service.cpp, which causes the linker to complain when linking
libinit.a in some situations.
Therefore, we move property_service.cpp to libinit.
Separately, this will make it easier to write tests for
property_service.cpp, which we will want to do in the future.
Test: build, init unit tests

The shared libselinux library does not export all of the symbols that
we use in init and the linker is now complaining about this, so let's
use the static libselinux library in init_tests to match init itself.

Look for asan options under /data/asan so that multi-process coverage
can be enabled on a newly-started remote process without disabling
verity and without forcing it to be always-on.
Test: adb shell echo "include_if_exists=/data/asan/asan.options.%b" >>
/system/asan.options && adb shell echo
"coverage=1\ncoverage_dir=/data/misc/trace" >

bootstat does not need root uid and root gid permissions to perform
its tasks. It appears that system uid and log gid are adequate and
appropriate.
