Commit 780a71e7 changed ueventd's selinux label lookup from /dev/input/
to /dev/input which no longer matches the regex in core policy
file_contexts. Fix the regex to match /dev/input and /dev/input/.

avc: denied { read } for name="input" dev="tmpfs" ino=14092
scontext=u:r:hal_camera_default:s0 tcontext=u:object_r:device:s0
tclass=dir
avc: denied { open } for path="/dev/input" dev="tmpfs"
ino=14092 scontext=u:r:hal_camera_default:s0
tcontext=u:object_r:device:s0 tclass=dir

Test: no camera HAL denials

This patch tries to provide similar functionality as the previous
change made here:
https://android-review.googlesource.com/#/c/platform/system/sepolicy/+/432339/



Only, making sure we add the same map permissions for the vendor
directory.

Configstore HAL uses a seccomp filter which blocks the standard
path of execing crash_dump to collect crash data. Add permission
to use crash_dump's fallback mechanism.

Allowing configstore to write to the socket provided by tombstoned
required either exempting configstore from a neverallow rule, or
removing the neverallow rule entirely. Since the neverallow rule
could potentially prevent partners for doing security hardening,
it has been removed.

Vendor HAL extentsions are currently allowed to discover hardware
services that are labelled with 'untrusted_app_visible_hwservice'.
However, the policy doesn't allow these apps to talk to these services.
This CL makes sure that is now possible via the
'untrusted_app_visible_halserver' attribute for vendor domains that host
such a service.

will are not made visible to applications by default. They are:
  hal_neuralnetworks_hwservice

  system_net_netd_hwservice
  thermalcallback_hwservice

The treble compatibility tests check for policy differences between old
and new policy.  To do this correctly, we must not modify the policy which
represents the older policies.  Move the files meant to be changed to a
different location from the ones that are not meant to be touched to avoid
any undesired changes to old policy, e.g. commit:
2bdefd65078d890889672938c6f0d2accdd25bc5

untrusted_app_visible_hwservice was an attribute that was meant to
give partners time to add their HALs to AOSP.  It was removed from mr1
and so needs to be accounted for in the compatibility mapping.

On Full Treble devices, servicemanager should only service
services from the platform service_contexts file.

Created new type to separate plat_ and nonplat_service_contexts,
and added new type to mapping (although I don't think this type
should have been used by vendors).

Add support to the treble_sepolicy_tests suite that explicitly look at
the old and current policy versions, as well as the compatibility file,
to determine if any new types have been added without a compatibility
entry.  This first test catches the most common and likely changes that
could change the type label of an object for which vendor policy may have
needed access.  It also should prove the basis for additional compatibility
checks between old and new policies.

Bug: 36899958
Test: Policy builds and tests pass.

A new API [getNamesForUids] was recently added to the PackageManager
and this API needs to be accessible to native code. However, there
were two constraints:
1) Instead of hand-rolling the binder, we wanted to auto generate
the bindings directly from the AIDL compiler.
2) We didn't want to expose/annotate all 180+ PackageManager APIs
when only a single API is needed.
So, we chose to create a parallel API that can be used explicitly
for native bindings without exposing the entirety of the
PackageManager.

Commit: ec3b6b7e added a new daemon
