This CL changes a neverallow for /vendor apps accessing vendor_service.
Originally, /vendor apps ({appdomain -coredomain}) were disallowed from
accessing all AIDL services since they are platform implementation
details that may change over time, and these apps run in a system
context. However, now, vendor services can be stable. So, in order to
give the flexibility needed for vendor framework components installed to
the /vendor partition to access AIDL HALs, opening this up.

TimeZoneDetectorService will be accessed as part of a new @SystemApi,
TimeManager.
For CTS testing, the TimeZoneDetectorService needs to be accessible by
the CTS test app, this means the sepolicy for the service needs to be
expanded to less trusted clients. During tests we can expand the Android
permissions to those of the Shell process, but it looks like selinux
still needs this change even though "real" clients will be privileged
apps.
It's probable that the time / time detector services will be used in
public SDK TimeManager APIs in the future.

ro.boot. properties assigned as "exported2_default_prop" are now
"bootloader_prop", to remove bad context name "exported2_default_prop".
Two things to clarify:
1) We have both the prefix entry and the exact entries. Although the
exact entries may be redundant, we may want to keep them. Vendors are
still allowed to have properties starting with "ro.boot." on
vendor_property_contexts file. The exact entries can prevent vendors
from modifying them to random contexts.
2) ro.boot. is special as it is originally for kernel command line
"androidboot.". But some ro.boot. properties are being used as if they
were normal. To avoid regression, ro.boot. properties having contexts
other than "exported2_default_prop" are not changed here. They will be
tracked later.

We have various apps which inherently work across all users,
configured in seapp_contexts with levelFrom=None (usually implicitly).
This change marks those apps, where they have private data files, as
mlstrustedsubject, to allow us to increase restrictions on cross-user
access without breaking them.
Currently these apps are granted full access to [priv_]app__data_file
via TE rules, but are blocked from calling open (etc) by mls rules
(they don't have a matching level).
This CL changes things round so they are granted access by mls, but
blocked from calling open by TE rules; the overall effect is thus the
same - they do not have access.
A neverallow rule is added to ensure this remains true.
Note that there are various vendor apps which are appdomain,
levelFrom=None; they will also need modified policy.
