This change splits out the selinux initialization and supporting functionality into selinux.cpp and splits the security related initialization of the rng, etc to security.cpp. It also provides additional documentation for SEPolicy loading as this has been requested by some teams. It additionally cleans up sehandle and sehandle_prop. The former is static within selinux.cpp and new wrapper functions are created around selabel_lookup*() to better serve the users. The latter is moved to property_service.cpp as it is isolated to that file for its usage. Test: boot bullhead Merged-In: Idc95d493cebc681fbe686b5160502f36af149f60 Change-Id: Idc95d493cebc681fbe686b5160502f36af149f60 (cherry picked from commit 9afb86b25d8675927cb37c86119a7ecf19f74819)
