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.

Location of mapping files has changed from private/mapping/V.v.cil to
private/compat/V.v/V.v.cil
Change the build rule for current_mapping.cil to reflect that.

Test: Build current mapping file with  BOARD_SEPOLICY_VERS := 27.0 and
make sure that $OUT/obj/ETC/27.0.cil_intermediates/27.0.cil is not empty

When extraction exif info, certain file formats may requires
parsing the container. Allow mediaprovider to use extractor
to do the parsing.

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.

Several /odm/* symlinks are added in the following change, to fallback
to /vendor/odm/* when there is no /odm partition on the device.

  https://android-review.googlesource.com/#/c/platform/system/sepolicy/+/638159/

This change allows dexopt operations to 'getattr' those symlinks during
OTA.

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.

Allow init the ability to relabel recovery block devices. In the case
where we have recovery as a chain partition, due to its presence in
early mount node, init, in first stage itself would require relabel
permissions for the restorecon operation on recovery block device.

Bug: 73642793
Test: On bootup, recovery partition gets the appropriate se-label.
      Perform OTA on non-A/B device with recovery as chain partition,
      now the recovery partition gets upgraded successfully, now that
      it has the correct se-label.
