As described in the system/core commit with the same Change-Id,
there's a race condition between installd and sdcard when it
comes to accessing /data/media. Resolve the race by checking
/data/.layout_version to make sure the filesystem has been upgraded.

Maybe indirectly fixes the following SELinux denial:

  sdcard  : type=1400 audit(0.0:3): avc: denied { write } for name="media" dev="mmcblk0p17" ino=102753 scontext=u:r:sdcardd:s0 tcontext=u:object_r:system_data_file:s0 tclass=dir

https://android-review.googlesource.com/94851 added an LD_PRELOAD
line to init.environ.rc.in. This has the effect of loading
libsigchain.so into every process' memory space, regardless of
whether it wants it or not.

For lmkd, it doesn't need libsigchain, so it doesn't make any sense
to load it and keep it locked in memory.

Disable noatsecure for lmkd. This sets AT_SECURE=1, which instructs the
linker to not honor security sensitive environment variables such
as LD_PRELOAD. This prevents libsigchain.so from being loaded into
lmkd's memory.

system_server auditallow statements were causing logspam and
there is not a good way to negate services from specific devices
so as a fix we are removing all system_server auditallows. These
logs may not be useful anyway because I suspsect that system_server
will probe for most all services anyway.

dex2oat can't access file descriptors associated with asec_apk_files.
This breaks installing forward locked apps, and generates the following
denial:

  $ adb install -r -l SimpleJNI.apk

  app installs

1) Remove explicit allow statements. Since su is in permmissive,
there's no need to ever specify allow statements for su.

2) Remove unconfined_domain(su). Su is already permissive, so there's
no need to join the unconfined domain, and it just makes getting
rid of unconfined more difficult.

3) Put su into app_domain(). This addresses, in a roundabout sorta
way, the following denial:

  type=1400 audit(0.0:4): avc: denied { setsched } for scontext=u:r:system_server:s0 tcontext=u:r:su:s0 tclass=process permissive=0

which comes up while testing media processes as root. We already put
the shell user into this domain, so adding su to this domain ensures
other processes can communicate consistently with su spawned processes.

Currently, dex2oat runs in the installd sandbox, and has
all the SELinux capabilities that installd does. That's too
excessive.

dex2oat handles untrusted user data, so we want to put it in
it's own tighter sandbox.
