Since each dropbox entry is already stored as a file on disk, include
them as-is into the dumpstate ZIP file.
The dumpsys output has already included truncated versions of all
dropbox entries for many years, and adding them as separate files
inside the dumpstate ZIP will speed up debugging and issue triage.

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.

Android R launching devices and newer must not ship with debugfs
mounted. For Android S launching devices and newer, debugfs must only be
mounted in userdebug/eng builds by init(for boot time initializations)
and dumpstate(for grabbing debug information from debugfs using the
dumpstate HAL).
This patch adds neverallow statements to prevent othe processes
being provided access to debugfs when the flag PRODUCT_SET_DEBUGFS_RESTRICTIONS
is set to true.

Feature description: if a background trace is happening at the
time dumpstate is invoked, the tracing daemon will snapshot
the trace into a fixed path (/data/misc/perfetto-traces/bugreport/).
Dumpstate will attach the trace, if present, to the bugreport.
From a SELinux viewpoint this involves the following permissions:
- Allow dumpstate to exec+trans perfetto --save-for-bugreport
(this will just send an IPC to traced, which will save the trace).
- Allow dumpstate to list, read and unlink the trace file.
- Create a dedicated label for bugreport traces, to prevent that
dumpstate gets access to other traces not meant for bug reporting.
Note that this does NOT allow dumpstate to serialze arbitary traces.
Traces must be marked as "eligible for bugreport" upfront in the
trace config (which is not under dumpstate control), by
setting bugreport_score > 0.
Design doc: go/perfetto-betterbug
Bug: 170334305
Test: manual:
1. start a perfetto trace with bugreport_score > 0
2. adb shell dumpstate
3. check that the bugreport zip contains the trace
