The kernel generates file creation audits when O_CREAT is passed even
if the file already exists - which it always does in the cgroup cases.
We add neverallow rules to prevent mistakenly allowing unnecessary
create access. We also suppress these denials, which just add noise to
the log, for the more common culprits.

In permissive mode we get more spurious denials when O_CREAT is used
with an already-existing file. They're harmless so we don't need to
audit them.
Example denials:
denied { add_name } for name="trigger" scontext=u:r:init:s0 tcontext=u:object_r:sysfs_leds:s0 tclass=dir permissive=1
denied { create } for name="trigger" scontext=u:r:init:s0 tcontext=u:object_r:sysfs_leds:s0 tclass=file permissive=1

Verify that the SELabels used in property_contexts correspond to a
real type in the SEPolicy and that this type has the property_type attribute.
Additionally add a check that vendor property_context files do not
duplicate entries in plat property_contexts, and a similar check that
odm property_contexts doesn't duplicate either plat or vendor
property_contexts.

This allows an optimization that consists in the "perfetto" cmdline
client passing directly the file descriptor for the output trace
to traced (as opposite to having traced streaming back the trace
data to "perfetto" and having that one doing the write() into file).
This reduces sensibly the memory traffic and CPU overhead of traces
with a minor change.

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 better record the network traffic stats for each network interface.
We use xt_bpf netfilter module to do the iface stats accounting instead
of the cgroup bpf filter we currently use for per uid stats accounting.
The xt_bpf module will take pinned eBPF program as iptables rule and run
the program when packet pass through the netfilter hook. To setup the
iptables rules. netd need to be able to access bpf filesystem and run the
bpf program at boot time. The program used will still be created and
pinned by the bpfloader process.
Test: With selinux enforced, run "iptables -L -t raw" should show the
xt_bpf related rule present in bw_raw_PREROUTING chain.

This change adds the support of odm sepolicy customization, which can
be configured through the newly added build varaible:
- BOARD_ODM_SEPOLICY_DIRS += device/${ODM_NAME}/${BOM_NAME}/sepolicy
Also moving precompiled sepolicy to /odm when BOARD_ODM_SEPOLICY_DIRS
is set. On a DUT, precompiled sepolicy on /odm will override the one in
/vendor. This is intentional because /odm is the hardware customization
for /vendor and both should be updated together if desired.
Bug: 64240127
Test: boot a device with /odm partition
