security: integration of security-manager

Allows the integration to AGL of the security security framwork
coming from tizen. It includes smack, cynara, security-manager and
other dependant components.

Most of this components are coming from a work made by Intel OTC to
create a yocto layer focused on security framework. This public work
available here https://github.com/01org/meta-intel-iot-security
has parts derived from Tizen's works and adds integrity parts.

This patch also removes dependencies to tizen-platform-config,
libslp-db-utils and dlog.

+security-manager adaptation for Automotive Grade Linux Distribution
+===================================================================
+
+This recipe complements the recipes security-manager of the
+meta yocto layers: meta-intel-iot-security (see
+https://github.com/01org/meta-intel-iot-security)
+
+This patches are removing dependencies that are specific to Tizen:
+* tizen-platform-config
+* libslp-db-utils
+
+The advantages is that this modules are not needed for AGL.
+
+The -temporary- drawbacks is that the user "userapp" is
+hard coded for security-manager.

+
+To enable security manager for AGL, in the local.conf
+
+    IMAGE_INSTALL_append = " security-manager"
+
+To enable smack see https://github.com/01org/meta-intel-iot-security/tree/master/meta-security-smack
+In brief, in the local.conf:
+
+    OVERRIDES .= ":smack"
+    DISTRO_FEATURES_append = " smack"
