Currently shell can connect to the traced_consumer_socket allowing it to
configure/start/stop and collect traces. This allows a host tool (e.g. Android Studio or
https://ui.perfetto.dev) to connect to the device via adb and collect traces. It would
be better if rather than executing shell commands the host tool could directly communicate
with the consumer socket. This is possible using adb forward:
adb forward tcp:9903 localfilesystem:/dev/socket/traced_consumer
However in this case adbd is connecting to the socket - not shell.
This CL allows adbd to connect to the socket which allows host tools to collect
traces without having to do everything though shell commands.
Note that this patch also has additional change on prebuilts in order to
backport.

(cherry-picked from commit b56a49d979)
Due to Factory OTA client install in product partition but it also declare coredomian in
its sepolicy setting. That will let Factory OTA unable to find a property type could write system property.
But now Factory OTA have a restore NFC wake function need to write system property for communicate with bootloader.
So we need to create a new property type in system framework which could allow Factory OTA client to write system property.

- Android Auto has disabled background dexopt (b/142753051).
- The modification is in car_base.mk which is included by vendor device
file.
- So, vendor_init needs to be able to modify
pm.dexopt.disable_bg_dexopt property.

Test: Check pm.dexopt.disable_bg_dexopt is set to true in Android Auto
device.

The commit 7baf725ea6 broke OMX on O/O-MR1(/P?) vendors.
Previous to this commit, all OMX codecs had to use "mediacodec" type,
after this commit, omx codecs just had to get hal_omx_server attribute.
This commit left to the vendor the charge of adding "hal_omx_server"
attribute to mediacodec.
However this can't work on non-Q vendors.
On P vendor, versioned_plat_pub contains the appdomain <=> mediacodec
allows, so OMX isn't technically broken on those devices.
But to ensure it won't break in the future, mark 28's mediacodec as
hal_omx_server as well
This fixes broken OMX decoding on O/O-MR1 vendors, failing with the
following denial:

ro.crypto.fde_algorithm

These properties were not added to sepolicy export2vold. vold can't access
crypto algorithm type when flashing a GSI image and when the properties are in
/vendor/build.prop. This prevents FDE from working.

SELinux has a separate file mmap permission in 4.14+ kernels. Add this
to dexoptanalyzer(d) in cases where it could already access files (in
particular, secondary dex files).
Addresses denials of the form:
avc: denied { map } for […] path="/data/data/[…]" […]
