With sdcardfs, we no longer have a separate sdcardd acting as
an intermediate between the outside world and /data/media.
Unless we modify sdcardfs to change contexts, we need these.

Remove this patch if sdcardfs is updated to change the
secontext of fs accesses.

To write bytes to appfuse file from priv_app, we need to specify
mlstrustedobject.
The CL fixes the following denial.

Similar to profman, dex2oat does more checks on profiles now.
It needs to be able to do stat to test for existance and non-emptiness.

We do a bit more work checks in the runtime for the profiles and call
stat on the files to see if they exists and their are not empty.

One time executables. recovery_refresh can be used at any time to

recovery_persist takes the recovery logs in pmsg and drops them

The changes to ptrace in
https://android-review.googlesource.com/#/c/175786/ (removing it from
app.te and only adding it to isolated_app and untrusted_app) broke
WebView crash handling in cases where privileged apps (like gmscore) use
WebView.

The only way to fix this would be to allow priv_app to self-ptrace as
well. :/

Applications do not explicitly request handles to the batteryproperties
service, but the BatteryManager obtains a reference to it and uses it
for its underlying property queries.  Mark it as an app_api_service so
that all applications may use this API.  Also remove the batterypropreg
service label, as this does not appear to be used and may have been a
duplication of batteryproperties.  As a result, remove the
healthd_service type and replace it with a more specific
batteryproperties_service type.

Many permissions were removed from untrusted_app by the removal of
domain_deprecated, including procfs access. procfs file access was restored,
however, but not completely.  Add the ability to getattr to all domains,
so that other domains which lost domain_deprecated may benefit, as they
will likely need it.
