This will allow adb shell getprop ro.vendor.build.security_patch to
properly return the correct build property, whereas previously it was
offlimits due to lack of label.

Test: adb shell getprop ro.vendor.build.security_patch successfully
returns whatever VENDOR_SECURITY_PATCH is defined to be in the Android

This reverts commit 6f2040f8.

Reason for revert: not needed anymore after ag/3773705
This was meant to allow system_server toggling the property on/off.
Later we realized that we needed a separate property for that 
(see discussion in b/76077784) and system server happens to
have already permissions to write to sys.* properties even without
this CL.
Reverting because at this point this creates just unnecessary clutter.

Bug: 76077784

To enable/disable the traced and traced_probes deamons remotely we would
like system server to be able to set persist.traced.enable.
See also ag/3736001.

Denial:
selinux: avc: denied { set } for
property=persist.traced.enable
pid=1606 uid=1000 gid=1000
scontext=u:r:system_server:s0
tcontext=u:object_r:default_prop:s0 tclass=property_service
permissive=0\x0a

Run:
$ adb shell 'ps -A | grep traced'
Should see traced.
$ adb shell 'settings put global sys_traced 0'
$ adb shell 'ps -A | grep traced'
Should no longer see traced.

Test: See above.

The feature of compatible property has its own neverallow rules and it
is enforced on devices launchig with Android P.

This CL changes hal_nfc to hal_nfc_server in neverallow rules because
sepolicy-analyze doesn't recognize it. Additionally one more neverallow
rule is added to restrict reading nfc_prop.

The current neverallow rules for compatible properties restrict
domains from write file permissions to the various property files.
This however is the wrong restriction, since only init actually writes
to these property files.  The correct restriction is to restrict 'set'
for 'property_service' as this change does.

Note there is already a restriction preventing {domain -init} from
writing to these files in domain.te.

This CL lists all the exported platform properties in
private/exported_property_contexts.

Additionally accessing core_property_type from vendor components is
restricted.
Instead public_readable_property_type is used to allow vendor components
to read exported platform properties, and accessibility from
vendor_init is also specified explicitly.

Note that whitelisting would be applied only if
PRODUCT_COMPATIBLE_PROPERTY is set on.

Switch from /data/misc/reboot/last_reboot_reason to persistent
Android property persist.sys.boot.reason for indicating why the
device is rebooted or shutdown.

Introduce protection for all boot reason properties

Protect the following properties with these labels

ro.boot.bootreason      u:object_r:bootloader_boot_reason_prop:s0
sys.boot.reason         u:object_r:sys_boot_reason_prop:s0
persist.sys.boot.reason u:object_r:last_boot_reason_prop:s0

This change did not make it into core sepolicy in time for O.
The revert allows devices to define these selinux policies in
vendor-specific sepolicy instead of core sepolicy. It is
necessary because:

1. It is too late to change property_contexts in O.
2. Adding the netd_stable_secret prop to vendor sepolicy results
   in a duplicate definition error at compile time.
3. Defining a new vendor-specific context (such as
   net_stable_secret_vendor_prop) and applying it to
   persist.netd.stable_secret results in the device not booting
   due to attempting to apply two different contexts to the same
   property.

Lack of the sepolicy no longer breaks wifi connectivity now that
IpManager no longer considers failure to set the stable secret to
be a fatal error.

Once all interested devices have adopted the vendor sepolicy,
this policy can safely be reinstated by reverting said vendor
sepolicies in internal master.

This reverts commit abb1ba65.

This is used to persist RFC 7217 stable secrets across device reboots.

First submit caused a merge conflict. This revision replaces netd_prop
with a more unique name netd_stable_secret_prop.

Test: as follows
    - Manually tested that stable_secret is generated on first use and
      persists until reset of user data partition (factory reset).
    - Tested that "adb shell getprop" was denied access to
      persist.netd.stable_secret after running "adb unroot".

This is a partial revert of commit 82672089.
The previous commit removed a public type, which is a version-incompatible
change to the SELinux vendor API.  Since the 2017 devices are meant to be
launching with the previous version, this is unacceptable.  Revert the
version-incompatible parts of the change, but keep the other parts to enable
existing system functionality to persist and become part of MR1.  Leave TODOs
to remove the other parts when a version bump is acceptable.
