This will allow adb shell getprop ro.vendor.build.security_patch to
properly return the correct build property, whereas previously it was
offlimits due to lack of label.

Test: adb shell getprop ro.vendor.build.security_patch successfully
returns whatever VENDOR_SECURITY_PATCH is defined to be in the Android
.mk files

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
to give traceur a UX friendly area to write its traces to now that it
will no longer be a shell user. It will be write/readable by traceur,
and deletable/readable by shell.

system_update service manages system update information: system updater
(priv_app) publishes the pending system update info through the service,
while other apps can read the info accordingly (design doc in

This CL lists all the exported platform properties in
private/exported_property_contexts.

Additionally accessing core_property_type from vendor components is
restricted.
Instead public_readable_property_type is used to allow vendor components
to read exported platform properties, and accessibility from
vendor_init is also specified explicitly.

Note that whitelisting would be applied only if
PRODUCT_COMPATIBLE_PROPERTY is set on.

Perfetto is a performance instrumentation and logging framework,
living in AOSP's /external/pefetto.
Perfetto introduces in the system one binary and two daemons
(the binary can specialize in either depending on the cmdline).

1) traced: unprivileged daemon. This is architecturally similar to logd.
   It exposes two UNIX sockets:
   - /dev/socket/traced_producer : world-accessible, allows to stream
     tracing data. A tmpfs file descriptor is sent via SCM_RIGHTS
     from traced to each client process, which needs to be able to
     mmap it R/W (but not X)
   - /dev/socket/traced_consumer : privilege-accessible (only from:
     shell, statsd). It allows to configure tracing and read the trace
     buffer.
2) traced_probes: privileged daemon. This needs to:
   - access tracingfs (/d/tracing) to turn tracing on and off.
   - exec atrace
   - connect to traced_producer to stream data to traced.
