Allow /proc/meminfo to be read by bootanim. Not sure why
it's needed, but harmless enough.

Modify domain_deprecated so it doesn't use r_dir_file().
/proc/meminfo is neither a symlink nor a directory, so it doesn't
make sense to create allow rules for those classes of objects.

Addresses the following denial:

  avc: denied { read } for comm="BootAnimation" name="meminfo" dev="proc"
  ino=4026536593 scontext=u:r:bootanim:s0
  tcontext=u:object_r:proc_meminfo:s0 tclass=file permissive=0

This denial is only showing up on flounder, flounder_lte, or
dragon devices. I'm not sure why.

Was moved to domain_deprecated. Move back to domain.

Files in /acct/uid/*/tasks are well protected by unix permissions.
No information is leaked with write perms.

Access to /proc/cpuinfo was moved to domain_deprecated in commit
6e3506e1. Restore access to everyone.

Allow the shell user to stat() /dev, and vfsstat() /proc and other
labeled filesystems such as /system and /data.

Access to /proc/cpuinfo was explicitly granted to bootanim, but is no
longer required after moving it back to domain.te. Delete the redundant
entry.

Commit 4e2d2245 restored access to
/sys/devices/system/cpu for all domains, but forgot to remove the
redundant entry from bootanim.te. Cleanup the redundant entry.

Addresses the following denials:

  avc: denied { getattr } for pid=23648 comm="bionic-unit-tes" name="/" dev="proc" ino=1 scontext=u:r:shell:s0 tcontext=u:object_r:proc:s0 tclass=filesystem permissive=0
  avc: denied { read } for name="cpuinfo" dev="proc" ino=4026533615 scontext=u:r:shell:s0 tcontext=u:object_r:proc_cpuinfo:s0 tclass=file permissive=0

Start labeling the directory /sys/kernel/debug/tracing. The files
in this directory need to be writable to the shell user.

Remove global debugfs:file write access. This was added in the days
before we could label individual debugfs files.

Remove domain_deprecated from bootanim. This removes some unnecessarily
permissive rules.

As part of this, re-allow access to cgroups, proc and sysfs, removed as
a result of removing domain_deprecated.

Motivation: Domain is overly permissive. Start removing permissions
from domain and assign them to the domain_deprecated attribute.
Domain_deprecated and domain can initially be assigned to all
domains. The goal is to not assign domain_deprecated to new domains
and to start removing domain_deprecated where it is not required or
reassigning the appropriate permissions to the inheriting domain
when necessary.

All domains are currently granted list and find service_manager
permissions, but this is not necessary.  Pare the permissions
which did not trigger any of the auditallow reporting.

A DO NOT MERGE change merged from lmp-dev to lmp-dev-plus-aosp.
This is expected, but it's causing unnecessary merge conflicts
when handling AOSP contributions.

Resolve those conflicts.

This is essentially a revert of bf696327
for lmp-dev-plus-aosp only.

Change-Id: Icc66def7113ab45176ae015f659cb442d53bce5c

Remove the audit_allow rules from lmp-dev because
we will not be tightening any further so these logs
will not be useful.

Leave the domain permissive initially until it gets more testing.
