Set TARGET_CPU_VARIANT.
Fix fstab name.
Remove depreciated config_wifi_p2p_support overlay.
libaudio: Include liblog.
Bump system image size limit.

Previous value was much lower than actual system parition
size.  Newer build sizes are larger than the previous value
and caused an error during the build process.  Increase the
size limit to the /system partition size to allow for proper
error checking.
releasetools: Fix selinux typo.
Initial sepolicy.
Add restorecon.sh

After flashing, /system is left unlabeled.  This is not
picked up by the init.d script, so manually restore selinux
labels at the end of the updater-script.
Fix fstab.
