security: integration of security-manager

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.
