The "su" domain is in globally permissive mode on userdebug/eng
builds. No SELinux denials are suppose to be generated when running
under "su".
Get rid of useless SELinux denials coming from su trying to stat
files in /dev/__properties__. For example: "ls -la /dev/__properties__"
as root.
Addresses the following denials:
avc: denied { getattr } for pid=14692 comm="ls" path="/dev/__properties__/u:object_r:wc_transport_prop:s0" dev="tmpfs" ino=10597 scontext=u:r:su:s0 tcontext=u:object_r:wc_transport_prop:s0 tclass=file permissive=1

Per https://android-review.googlesource.com/185392 , ctl.* properties
are not represented as files in the filesystem. So there's no need
to grant read access to them, since it's pointless.
Remove core_property_type from these properties, which has the net
effect of removing read access to these non-existent files.

Instead of allowing global read access to all properties,
only allow read access to the properties which are part of
core SELinux policy. Device-specific policies are no longer
readable by default and need to be granted in device-specific
policy.
Grant read-access to any property where the person has write
access. In most cases, anyone who wants to write a property
needs read access to that property.

Even though /dev/ion can allocate memory when opened in read-only mode,
some processes seem to unnecessarily open it in read-write mode.
This doesn't seem to be harmful, and was originally allowed in
domain_deprecated. Re-allow it.

The removal of domain_deprecated from the shell user in

Restore it.

Add initial support for labeling files on /sys/kernel/debug.
The kernel support was added in https://android-review.googlesource.com/122130
but the userspace portion of the change was never completed until now.
Start labeling the file /sys/kernel/debug/tracing/trace_marker . This
is the trace_marker file, which is written to by almost all processes
in Android. Allow global write access to this file.
This change should be submitted at the same time as the system/core
commit with the same Change-Id as this patch.

The removal of domain_deprecated broke the ability for adbd to
pull files from /sdcard. Re-allow it.

- Add a new 'dumpstate' context for system properties. This context
will be used to share state between dumpstate and Shell. For example,
as dumpstate progresses, it will update a system property, which Shell
will use to display the progress in the UI as a system
notification. The user could also rename the bugreport file, in which
case Shell would use another system property to communicate such
change to dumpstate.
- Allow Shell to call 'ctl.bugreport stop' so the same system
notification can be used to stop dumpstate.

Properties are now broken up from a single /dev/__properties__ file into
multiple files, one per property label. This commit provides the
mechanism to control read access to each of these files and therefore
sets of properties.
This allows full access for all domains to each of these new property
files to match the current permissions of /dev/__properties__. Future
commits will restrict the access.
