Currently, permissions for ctl. property apply to each action verb, so
if a domain has permissions for controlling service 'foo', then it can
start, stop, and restart foo.

This change implements finer grainer permissions such that permission
can be given to strictly start a given service, but not stop or
restart it.  This new permission scheme is mandatory for the new
control functions, sigstop_on, sigstop_off, interface_start,
interface_stop, interface_restart.

For devices shipped on O-MR1 nothing changes, data is stored
under /data/system/users/<user-id>/fpdata/...

Devices shipped from now on will instead store fingerprint data under
/data/vendor_de/<user-id>/fpdata.

Support for /data/vendor_de and /data/vendor_ce has been added to vold.

* Note on cherry-pick: Some of the dependent changes are not in AOSP.
In order to keep hostapd running correctly in AOSP, I've modified this
change to only include policy additions.

HIDL interface.

Values of the following properties are set by SoC vendors on some

- persist.bluetooth.a2dp_offload.cap
- persist.bluetooth.a2dp_offload.enable

This reverts commit 6f2040f8.

Reason for revert: not needed anymore after ag/3773705
This was meant to allow system_server toggling the property on/off.
Later we realized that we needed a separate property for that 
(see discussion in b/76077784) and system server happens to
have already permissions to write to sys.* properties even without
this CL.
Reverting because at this point this creates just unnecessary clutter.

To enable/disable the traced and traced_probes deamons remotely we would
like system server to be able to set persist.traced.enable.
See also ag/3736001.

Denial:
selinux: avc: denied { set } for
property=persist.traced.enable
pid=1606 uid=1000 gid=1000
scontext=u:r:system_server:s0
tcontext=u:object_r:default_prop:s0 tclass=property_service
permissive=0\x0a

Run:
$ adb shell 'ps -A | grep traced'
Should see traced.
$ adb shell 'settings put global sys_traced 0'
$ adb shell 'ps -A | grep traced'
Should no longer see traced.

Test: See above.

Instead of having statsd linking the perfetto client library
and talk directly to its socket, we let just statsd exec()
the /system/bin/perfetto cmdline client.

There are two reasons for this:
1) Simplify the interaction between statsd and perfetto, reduce
  dependencies, binary size bloat and isolate faults.
2) The cmdline client also takes care of handing the trace to
  Dropbox. This allows to expose the binder interaction surface
  to the short-lived cmdline client and avoid to grant binder
  access to the perfetto traced daemon.

This cmdline client will be used by:
 - statsd
 - the shell user (for our UI and Studio)

Fixing denials that stopped traceur from being able to write to
debugfs_tracing. Also cleaning up general find denials for services that
traceur doesn't have permission to access.

Additionally, labeling /data/local/trace as a trace_data_file in order
