perf_event_max_sample_rate is needed to be read for native profiling,
otherwise CTS test can fail on devices with kernel >= 4.4. Before this CL,
the file is not readable from untrusted_app domain. This CL makes it readable
from both shell domain and untrusted_app domain.

We simplified the way we track whether or not a dex file is used by
other apps. DexManager in the framework keeps track of the data and we
no longer need file markers on disk.

Test: device boots, foreign dex markers are not created anymore

We need more time to investigate the effect that this change will
have on DRM solutions. Until the investigation is done, revert.

Label /proc/misc and allow access to untrusted_apps targeting older API
versions, as well as update_engine_common.

/proc/misc is used by some banking apps to try to detect if they are
running in an emulated environment.

testing.

Test: Device boots and no new denials.
Change-Id: If1b97a9c55a74cb74d1bb15137201ffb95b5bd75

On devices without an actual vendor image, /vendor is a symlink to
/system/vendor. When loading a library from this symlinked vendor,
the linker uses resolve_paths() resulting in an lstat(). This
generates an selinux denial. Allow this lstat() so that paths can
be resolved on devices without a real vendor image.

This moves the CIL files comprising the split sepolicy to the
directories/partitions based on whether the file is part of
platform/system or non-platform/vendor. In particular:
* plat_sepolicy.cil is moved to /system/etc/selinux,
* nonplat_sepolicy.cil is moved to /vendor/etc/selinux, and
* mapping_sepolicy.cil is moved to /vendor/etc/selinux.

Test: Device boots, no additional denials. The test is performed both
      for a device without the CIL files and with the three CIL files.

The new wifi HAL manages the wlan driver and hence needs to be able to
load/unload the driver. The "wlan.driver.status" is used to indicate the
state of the driver to the rest of the system. There are .rc scripts for
example which wait for the state of this property.

This starts with the reduction in the number of services that
ephemeral apps can access. Prior to this commit, ephemeral apps were
permitted to access most of the service_manager services accessible
by conventional apps. This commit reduces this set by removing access
from ephemeral apps to:
* gatekeeper_service,
* sec_key_att_app_id_provider_service,
* wallpaper_service,
* wifiaware_service,
* wifip2p_service,
* wifi_service.

Test: Device boots up fine, Chrome, Play Movies, YouTube, Netflix, work fine.
