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)

Test: run dmesgd on a user device with injected KFENCE bugs

In virtualized deployments of Android, it can be useful to have
access to a description of the hypervisor/host environment being
used to run the guest OS instance.
This is represented by means of a new system property
ro.boot.hypervisor.version, which is meant to convey a
free-form descriptor of the current host/hypervisor version
The property is meant to be provided to Android as androidboot.
by whatever host-specific means are used to supply other boot
properties to the target Android instance. Access could be later
opened to other vendor processes to set if needed for specific
setups where init is not a sufficiently-early stage for
host/guest communication. Such setups are not known at this time.
For a native Android incantation, the property defaults to
being missing
Other properties could later be added to this same namespace
and context if they turn out to be useful in specific scenarios.

The system property "vold.post_fs_data_done" is used by init and vold to
communicate with each other in order to set up FDE on devices that use
FDE. It needs to be gettable and settable by vold, and settable by init
and vendor_init. This was the case in Android 11 and earlier; however,
the change
https://android-review.googlesource.com/c/platform/system/sepolicy/+/1277447
("Rename exported and exported2 vold prop") broke this by giving this
property the type "vold_config_prop", which made it no longer settable
by vold.
Since none of the existing property types appear to be appropriate for
this particular property, define a new type "vold_post_fs_data_prop" and
grant the needed domains permission to get/set it.
This is one of a set of changes that is needed to get FDE working again
so that devices that launched with FDE can be upgraded to Android 12.

These flags should be writeable to the shell for both root and non-root
users. They should be readable everywhere, as they're read in libc

These properties are non-persistent, are for local developer debugging
