This grants default access to the new GNSS subsystem for Linux to the
GNSS HAL default implementation. The GNSS subsystem creates character
devices similar to ttys but without much unneeded complexity. The GNSS
device class is specific to location use cases.

SLCAN setup requires certain ioctls and read/write operations to
certain tty's. This change allows the HAL to set up SLCAN devices while
complying with SEPolicy.
In addition to adding support for SLCAN, I've also included permissions
for using setsockopt. In order for the CAN HAL receive error frames from
the CAN bus controller, we need to first set the error mask and filter
via setsockopt.

This change is part of a topic that moves the recovery resources from the
system partition to the vendor partition, if it exists, or the vendor directory
on the system partition otherwise. The recovery resources are moving from the
system image to the vendor partition so that a single system image may be used
with either an A/B or a non-A/B vendor image. The topic removes a delta in the
system image that prevented such reuse in the past.
The recovery resources that are moving are involved with updating the recovery
partition after an update. In a non-A/B configuration, the system boots from
the recovery partition, updates the other partitions (system, vendor, etc.)
Then, the next time the system boots normally, a script updates the recovery
partition (if necessary). This script, the executables it invokes, and the data
files that it uses were previously on the system partition. The resources that
are moving include the following.
* install-recovery.sh
* applypatch
* recovery-resource.dat (if present)
* recovery-from-boot.p (if present)
This change includes the sepolicy changes to move the recovery resources from
system to vendor. The big change is renaming install_recovery*.te to
vendor_install_recovery*.te to emphasize the move to vendor. Other changes
follow from that. The net result is that the application of the recovery patch
has the same permissions that it had when it lived in system.
Bug: 68319577
Test: Ensure that recovery partition is updated correctly.

The audio HAL service name previously contained the audio HAL version
of the first audio HAL it supported.
Nevertheless, the same service can and do host all audio HAL versions.
Aka there is only one audio HAL service, and the version in its name is
technical dept and should not be changed.
This caused many confusions during vendor HAL upgrade as the
service version number was erroneously updated leading to
device boot loop.
The new service name is:
android.hardware.audio.service
The old one was:
android.hardware.audio@2.0-service
Keeping both names valid as most phones will not rename
the service immediately.

The space between 2K and 16K in /misc is currently reserved for vendor's

The change in the topic adds a `misc_writer` tool as a vendor module,
which allows writing data to the vendor space to bridge the gap in the
