Add a new selinux type for a system property used to hold metadata about
the time zone setting system property. Although system settings are
world readable, the associated metadata only needs to be readable by the
system server (currently).

ro.log.file_logger.path is a system property that liblog uses to
determine if file_logger should be used (instead of logd) and what file
the logs should be emitted to. It is primarily meant for non-Android
environment like Microdroid, and doesn't need to be set in Android. In
fact, setting it to a wrong value can break the system logging
functionality. This change prevents such a problem by assigning a
dedicated property context (log_file_logger_prop) to the property and
making it non-writable. (Note that it still has to be readable because
liblog reads it and liblog can be loaded in any process)

New ro.kernel.watermark_scale_factor property is used to store the
original value read from /proc/sys/vm/watermark_scale_factor before
extra_free_kbytes.sh changes it. The original value is necessary to
use the same reference point in case the script is invoked multiple
times. The property is set by init the first time script is invoked
and should never be changed afterwards.

Since the property is supposed to be used by vendor-side .rc file as

When apexd installs an apex without reboot, init also need to do some
work around the installation (e.g. terminating services from the apex
and remove data read from the apex and updating linker configuration
etc)
Apexd sets control properties to unload and load apex and init notifies
the completion with state properties.
These new properties are supposed to be used by apexd/init interaction.

These properties are used to inform keystore2 and the RemoteProvisioner
app how they should behave in the system in the event that RKP keys are
exhausted. The usual behavior in a hybrid system is not to take any
action and fallback to the factory provisioned key if key attestation is
requested and no remotely provisioned keys are available.
However, there are instances where this could happen on a device that
was intended to be RKP only, in which case the system needs to know that
it should go ahead and attempt to remotely provision new certificates or
throw an error in the case where none are available.
Test: New properties are accessible from the two domains

dmesgd is a daemon that collects kernel memory error reports.
When system_server notices that a kernel error occured, it sets the
dmesgd.start system property to 1, which results in init starting
dmesgd.
Once that happens, dmesgd runs `dmesg` and parses its output to collect
the last error report. That report, together with the headers containing
device- and build-specific information is stored in Dropbox.
Empirically, dmesgd needs the following permissions:
- execute shell (for popen()) and toolbox (for dmesg),
read system_log (for dmesg)
- read /proc/version (to generate headers)
- perform Binder calls to servicemanager and system_server,
find dropbox_service (for dropbox)
- create files in /data/misc/dmesgd (to store persistent state)

It is a system property that keeps the last CID used by the
virtualizationservice. Although the information is local to the
process, a new system property is justified because the information has
to be kept across multiple runs of the process. A file however is not
desirable because the information shouldn't be persisted.

This adds a new property prefix owned by snapuserd, for communicating
when the service is ready to accept connections (snapuserd.ready and

This also adds a new socket context. This is a seqpacket socket used to
