If in invalid policy file is loaded check_seapp outputs:

Error: Could not lod policy file to db: Success!

The "Success" value is from errno, which is not manipulated
by libsepol. Also, load should have an a in it!

Hardcode the error message to:

Error: Could not load policy file to db: invalid input file!

Test: That when providing an invalid sepolicy binary, that the output
message is correct.

Divide policy into public and private components.  This is the first
step in splitting the policy creation for platform and non-platform
policies.  The policy in the public directory will be exported for use
in non-platform policy creation.  Backwards compatibility with it will
be achieved by converting the exported policy into attribute-based
policy when included as part of the non-platform policy and a mapping
file will be maintained to be included with the platform policy that
maps exported attributes of previous versions to the current platform
version.

Eventually we would like to create a clear interface between the
platform and non-platform device components so that the exported policy,
and the need for attributes is minimal.  For now, almost all types and
avrules are left in public.

Test: Tested by building policy and running on device.

Bug: 31116514
Change-Id: If94a27a26181e40de5c5e60f5446de9ce2ccdba0
(cherry picked from commit 0f81e066)

No core android component needs access to /dev/snd/{seq,timer}, but
currently audioserver, bootanim, init, system_server and ueventd have
access. Seq and timer have been the source of many bugs in the past
[1]. Giving these files new labels without explicitly granting access
removes access from audioserver, bootanim, and system_server.
Init and ueventd still require access for /dev setup.

TODO: Explore unsetting CONFIG_SND_TIMER device kernels.
