(breaks vendor blobs, will have to be regenerated
after this CL)
This moves mediacodec to vendor so it is replaced with
hal_omx_server. The main benefit of this is that someone
can create their own implementation of mediacodec without
having to alter the one in the tree. mediacodec is still
seccomp enforced by CTS tests.

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.

shipping API version:
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.

Files in /proc/net leak information. This change is the first step in
determining which files apps may use, whitelisting benign access, and
otherwise removing access while providing safe alternative APIs.
To that end, this change:
* Introduces the proc_net_type attribute which will assigned to any
new SELinux types in /proc/net to avoid removing access to privileged
processes. These processes may be evaluated later, but are lower
priority than apps.
* Labels /proc/net/{tcp,tcp6,udp,udp6} as proc_net_vpn due to existing
use by VPN apps. This may be replaced by an alternative API.
* Audits all other proc/net access for apps.
* Audits proc/net access for other processes which are currently
granted broad read access to /proc/net but should not be including
storaged, zygote, clatd, logd, preopt2cachename and vold.

Vendor public libs are exposed to apps (not system), and their ABI
stability is guaranteed by vendor. Introducing new selinux type so that
we don't conflate concepts of same-process HAL and vendor public lib.
The former is exposed to all domains, while the latter should only be
acessible by apps.

- persist.bluetooth.a2dp_offload.enable
- persist.vendor.bluetooth.a2dp_offload.enable

This reverts commit 6f2040f873.
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.

Bug: 76077784
This CL adds the SELinux permissions required to execute
atrace and get userspace tracing events from system services.
This is to enable tracing of events coming from surfaceflinger,
audio HAL, etc.
atrace, when executed, sets a bunch of debug.atrace. properties
and sends an IPC via binder/hwbinder to tell the services to
reload that property.
This CL does NOT affect systrace. In that case (i.e. when
atrace is executed from adb/shell) atrace still runs in
the shell domain and none of those changes apply.

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.
